• 403 Forbidden when Deploying asp.net 4.0 site to IIS 7

  - by Jordan

  So I have an EC2 instance running, the URL NoWeatherSurprises.com I have the DNS pointing there, and I set up a new site in IIS 7 and pointed it to a folder. I used Visual Studios Web Developer 2010 express to publish to this folder. It now has the binaries and such. However if I go to NoWeatherSurprises.com I get the welcome to IIS 7 screen. I'd expect to go to my application If I navigate to http://noweathersurprises.com/weather/ [weather was the folder I published to under wwwroot] I get a 403 forbidden. I have no idea why, I am guessing that it is trying to do a directory listing or something instead of launching my MVC Application. So 2 problems in summary. It is not pointing the domain to the folder directly and I need to add /weather I am getting a 403 forbidden instead of the results of my home controller with the index action. I am new to IIS 7, I had been using IIS 6 and had a lot less trouble setting it up, but I suspect that's my own fault and i am just missing something. Thanks in advance for any help

• How do I prevent or override a group policy on Windows 7?

  - by Kevin

  A few months ago my company was purchased by a large corporation. We recently switched our network over to the large corporate network which has more restrictions requirements. One of these is the requirement to use a proxy server for Internet traffic. However, some of our internal servers are not recognized by the corporate DNS, so we need to provide the fully qualified domain name. For W7, we make changes to the Internet Properties for IE8 and Chrome to include our domain name as an exception to the proxy server (e.g., *.foobar.com). The problem is that a group policy that does not include our domain name is continually pushed out to my systems throughout the day. This requires me to make the appropriate changes to the Internet Properties several times a day in order to access our internal servers. Is there a way that I can prevent the group policy from being pushed to my systems or detect when the group policy is pushed and override it? I am an administrator on all of my systems. I do have Firefox installed which is not subject to the same group policy push, but I need to have IE8 and Chrome working.

• Exchange 2010 Mail Enabled Public Folder Unable to Recieve External (anon) e-mail.

  - by Alex

  Hello All, I am having issues with my "Public Folders" mail enabled folders receiving e-mails from external senders. The folder is setup with three Accepted Domains (names changed for privacy reasons): 1 - domain1.com (primary & Authoritative) 2 - domain2.com (Authoritative) 3 - domain3.com (Authoritative) When someone attempts to send an e-mail to [email protected] from inside the organization, the e-mail is received and placed in the appropriate folder. However, when someone tries to send an e-mail from outside the organization (such as a gmail account), the following error message is received: "Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 Recipient address rejected: User unknown (state 14)." When I try to send an e-mail to the same folder, using the same e-mail address above ([email protected]), but with domain2.com instead of domain3.com, it works as intended (both internal & external). I have checked, double checked, and triple checked my DNS settings comparing those from domain2 & domain3 with them both appearing identical. I have tried recreating the folders in question with the same results. I have also ran Get-PublicFolderClientPermission "\Web Programs\folder" with the following results for user anonymous: RunspaceId : 5ff99653-a8c3-4619-8eeb-abc723dc908b Identity : \Web Programs\folder User : Anonymous AccessRights : {CreateItems} Domain2.com & Domain3.com are duplicates of each other, but only domain2.com works as intended. All other exchange functions are functioning properly. If anyone out there has any suggestions, I would love to hear them. I've just hit a brick wall. Thanks for all your help in advance! --Alex

• fast way to find network user computer on domain hogging all wan bandwidth

  - by dasko

  i have a network of about 40 domain users and i have huge latency wan issues, like 1400ms for google.com pings. I have noticed that the problem goes away after everyone goes home for the day. I would like to know if i should use something like a hub with wireshark on the router or modem to see if there are any irregular activity. I am open to suggestions but i need to isolate which user has the bug. I am assuming it is either downloads or someone spamming out heavily and not knowing. It would be best to trace to ip number so i can just look into dns and find the pc hostname with the problem? This is the first client i have this problem with so never really needed to address it before but not suprised as users don't actually listen to any best practices that we have suggested. Please help, thanks. just to update, pc's to routers and other computers have ping latency of 1ms so it is right after i hit the wan, using tracert to a web site (random), that i get the massive delay in the responses. As well this is a dsl line with 5mb down and 650kb up (maybe upload saturation?) thanks.

• I had a power outage. Now MySQL's lock file won't go away. What do you suggest?

  - by jasonspiro

  I do freelance IT consulting for various clients, both in Toronto, Canada, and worldwide. A client recently experienced a power failure. Now they've been having various problems with a Slackware 12.0.0 machine which also acts as a DNS server. One problem is that they can't log into phpMyAdmin. I tried stopping and restarting MySQL. But even when MySQL is stopped, the lock file stays around. jasonspiro@cybertron:~$ sudo /etc/init.d/mysql stop Shutting down MySQL. SUCCESS! jasonspiro@cybertron:~$ sudo /etc/init.d/mysql stop ERROR! MySQL manager or server PID file could not be found! jasonspiro@cybertron:~$ sudo /etc/init.d/mysql status ERROR! MySQL is not running, but lock exists jasonspiro@cybertron:~$ ls -l /var/lock/subsys/mysql -rw-r--r-- 1 root root 0 2012-07-05 16:18 /var/lock/subsys/mysql Why is MySQL's lock file hanging around despite the fact that MySQL isn't running? Can I simply stop MySQL, delete the lock file, and start MySQL again? Are there any other steps that I should take next, or nothing?

• Allow access from outside network with dmz and iptables

  - by Ivan

  I'm having a problem with my home network. So my setup is like this: In my Router (using Ubuntu desktop v11.04), I installed squid proxy as my transparent proxy. So I would like to use dyndns to my home network so I could be access my server from the internet, and also I installed CCTV camera and I would like to enable watching it from internet. The problem is I cannot access it from outside the net. I already set DMZ in my modem to my router ip. My first guess is because i'm using iptables to redirect all inside network to use squid. And not allow from outside traffic to my inside network. Here is my iptables script: #!/bin/sh # squid server IP SQUID_SERVER="192.168.5.1" # Interface connected to Internet INTERNET="eth0" # Interface connected to LAN LAN_IN="eth1" # Squid port SQUID_PORT="3128" # Clean old firewall iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X # Load IPTABLES modules for NAT and IP conntrack support modprobe ip_conntrack modprobe ip_conntrack_ftp # For win xp ftp client #modprobe ip_nat_ftp echo 1 > /proc/sys/net/ipv4/ip_forward # Setting default filter policy iptables -P INPUT DROP iptables -P OUTPUT ACCEPT # Unlimited access to loop back iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT # Allow UDP, DNS and Passive FTP iptables -A INPUT -i $INTERNET -m state --state ESTABLISHED,RELATED -j ACCEPT # set this system as a router for Rest of LAN iptables --table nat --append POSTROUTING --out-interface $INTERNET -j MASQUERADE iptables --append FORWARD --in-interface $LAN_IN -j ACCEPT # unlimited access to LAN iptables -A INPUT -i $LAN_IN -j ACCEPT iptables -A OUTPUT -o $LAN_IN -j ACCEPT # DNAT port 80 request comming from LAN systems to squid 3128 ($SQUID_PORT) aka transparent proxy iptables -t nat -A PREROUTING -i $LAN_IN -p tcp --dport 80 -j DNAT --to $SQUID_SERVER:$SQUID_PORT # if it is same system iptables -t nat -A PREROUTING -i $INTERNET -p tcp --dport 80 -j REDIRECT --to-port $SQUID_PORT # DROP everything and Log it iptables -A INPUT -j LOG iptables -A INPUT -j DROP If you know where did I miss, please advice me.

• OpenVPN: ERROR: could not read Auth username from stdin

  - by user56231

  I managed to setup openvpn but now I want to integrate a user/pass authentication method so, even though I haven't added the auth-nocache in the server config, whenever I try to connect it returns with the following message on the client side: ERROR: could not read Auth username from stdin My server.conf file contains basic stuff, everything works up untill I try to implement this for of authentication. mode server dev tun proto tcp port 1194 keepalive 10 120 plugin /usr/lib/openvpn/openvpn-auth-pam.so login client-cert-not-required username-as-common-name auth-user-pass-verify /etc/openvpn/auth.pl via-env ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt cert /etc/openvpn/easy-rsa/2.0/keys/server.crt key /etc/openvpn/easy-rsa/2.0/keys/server.key dh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem user nobody group nogroup server 10.8.0.0 255.255.255.0 persist-key persist-tun #persist-local-ip status openvpn-status.log verb 3 client-to-client push "redirect-gateway def1" push "dhcp-option DNS 10.8.0.1" log-append /var/log/openvpn comp-lzo I searched all over the net for a solution and all answers seems to be related to the auth-nocache param which I haven't set. The directive auth-user-pass-verify /etc/openvpn/auth.pl via-env points to a script which is executed to perform the authentication. A false authentication should result in a exit 1 while a true one should result with exit 0. For testing, that script auth.pl returns exit 0 no matter what the input is but it seems that the file is not executed before the error raises. auth.pl file contents: #!/usr/bin/perl my $user = $ENV{username}; my $passwd = $ENV{password}; printf("$user : $passwd\n"); exit 0; Any ideas?

• sendmail Name server timeout

  - by broody

  Complete sendmail newbie here... I've been trying to get mailing to work in PHP and I've root caused it down to sendmail's complaint about "Name server timeout": >sendmail -t -v >From: [email protected] >To: [email protected] >. gmail.com: Name server timeout [email protected]... Transient parse error -- message queued for future delivery [email protected]... queued So it sounds like a DNS issue? But I can do a "dig mx gmail.com" and it will query successfully. Here's what confuses me... I can get sendmail to work two other ways. The first way is through telnet: >telnet 127.0.0.1 25 >Helo me >Mail from: [email protected] >Rcpt to: [email protected] >. message sent And the second way is by explicitly appending the sendmail.cf, but this is strange because it's the exact same file I use to configure sendmail to begin with: >sendmail -t -v -C/etc/mail/sendmail.cf But none of these solutions will resolve my PHP mailing... I am clueless as to what is going on... appreciate any help.

• How do I get "Back to My Mac" (using MobileMe) from Windows?

  - by benzado

  I have a MobileMe subscription and a Mac at home with "Back to My Mac" enabled. When I'm away from home, this service lets me use another Mac to connect to my Mac back home and access file sharing, screen sharing, etc. As far as I know, the service doesn't use any proprietary protocols, so in theory I should also be able to get "Back to My Mac" from a Windows PC. This MacWorld article explains how it works. Basically, it uses Wide-Area Bonjour to give your Mac a domain name like hostname.username.members.mac.com. Remote computers can find your Mac using that address, then connect to it using a private VPN. The "Wide Area Bonjour" part seems to make it a little more complicated than simply a regular domain name, though. Note that I'm not interested in using the methods described by LifeHacker, which doesn't use the MobileMe service at all. I don't want to use a totally different dynamic DNS service. I'd like to use the one I'm already paying for, or at least find out why that's not possible from Windows. Also, my primary problem is finding a network route back to my mac... once I've got that I know how to enable services so that Windows can talk to it. UPDATE: Based on some additional research, it appears that Apple is only assigning IPv6 addresses to the hostname.username.members.mac.com names. So any solution will require enabling IPv6 support on Windows, if possible.

• Domain joined computer unable to access servers through VPN

  - by kscott

  Our servers are in a virtual off site hosting center, our office has a vpn connection to the data center, but for reasons I don't understand we also have to connect to the Citrix Access Gateway (CAG) client in order to access the servers. I am a programmer with rather limited ops knowledge including a weak grasp of networking and terminology. Bear with me. I was just given a new laptop, which is a 64 bit Windows 7 system unlike my previous 32 bit Windows XP desktop which was able to connect without issue. My laptop has been joined to the domain so that I login with my AD credentials, I am able to connect to the CAG and get authenticated, and after doing this I can ping our servers and they resolve to the correct internal IP addresses, but I am unable to use remote desktop to the servers, connect to SQL servers through my local SQL Management Studio, navigate to them through the file system, or view any of our internal intranet websites. All of which I was able to do previously. I have tried turning off my Windows firewall and the problem remains, the DNS servers are set to the correct IPs of our domain controllers, and the ops guys here are a little stumped. Does any one have any suggestions?

• Is the sysadmin/netadmin the defacto project planner at your organization?

  - by gft74

  At my company it has somehow over the past few years slowly become my job to come up with a project plan, milestones and time lines for deployment of developer applications. Typical scenario: My team receives a request for a new website/db combo and date for deployment. I send back a questionnaire for the developer to fill out on all the reqs for the site (ssl? db? growth projections etc.) After I get back all the information, the head of development wants a well developed document of what servers will it live on why those servers what is the time line for creating the resources step-by-step SOP for getting the application on the server and all related resources created (dns, firewall, load balancer etc.) I maybe just whining but it feels like this is something better suited to our Project Management staff (which we have) or to the developer. I understand that I need to give them a time-line on creating the resources, but still feel like this is overkill. We already produce documentation on where everything lives and track configuration changes to equipment. How do other sysadmin folks handle this?

• SSL in IIS 7 on a subdomain in a web farm

  - by justjoshingyou

  I have been having one of the most frustrating days in my entire IT career. I am trying to install an SSL certificate on a subdomain in a web farm. http://shop.mydomain.com needs to ALWAYS be forced to https://shop.mydomain.com I have a temporary cert issued from verisign on shop.mydomain.com I have installed the cert on the server. The website for shop.mydomain.com is set as a host header in IIS with the DNS entry pointed to the same IP as mydomain.com - which is our load balancer. I actually have 2 load balancers (as needed by our ISP). One redirects all traffic on port 80 out to the different servers on port 80. The other pushes out port 443 to the servers on port 443. shop.mydomain.com is to be the only site protected by SSL at this time. When I add the binding and I navigate to https://shop.mydomain.com it pops up with a warning about the cert being invalid (assumed because this is a test cert), and then it sends the user to http. So, I checked the box "Require SSL and it redirects to http://shop.mydomain.com/default.aspx and displayes an ASP.NET 404 error message. (not the IIS 404 error) I tried removing the binding on the site to port 80 as well with no luck. I am nearly ready to crawl under my desk into the fetal position. How on earth do I make this work? I can't even get it to work on one machine, let alone in the load balanced environment.

• Why do I have 55 local area connections in ipconfig?

  - by RMorrisey

  Windows Vista Home Premium. I should mention that I am having no problem whatever getting an internet connection. When I type "ipconfig" in the console, I get (55!) messages of 3 lines each, listing a ton of disconnected network connections. My PC only has one network card. Each message looks like this: Tunnel adapter Local Area Connection* 55: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : These don't cause a major problem; they make it a pain, though, to fish upward and find my IP address. How can I get rid of them? Edit: Actually, a few connection numbers are randomly missing from the sequence; so, it's really more like 30 or 40 connection messages, rather than all 55. Not sure why that is, either.

• Can't connect to public WiFi with MacBookPro at coffee shops and libraries

  - by Nathan Bowers

  The Problem: I can't connect to public, unencrypted WiFi at my local public library or Peets Coffee. My Setup: Late 2006 MacBookPro running 10.5.8. I have Parallels installed. It's supposed to work like this: 1) Connect to their unencrypted WiFi network 2) Open a browser which redirects you to their "enter password/agree to terms" page. 3) Browse normally. I can connect to the WiFi network, but when I try to authenticate I always get stuck in a redirect loop. It's been like this for a while. Even before I upgraded to 10.5.8. I never have trouble with encrypted networks or regular open WiFi. What I've tried: Disabling Parallels connections in Network Prefs. Superstition: somehow Parallels installed something in the network stack that's messing me up. Pinging the IP address of the WiFi node I'm connected to. I can ping it, it's there, but I still get stuck in this authentication redirect loop. Tried different browsers, tried different cookie and security settings. Even tried IE under Parallels. No dice. Tried flushing DNS cache. Asked library and coffee employees for help. It didn't go well. My Question: Anybody else have this problem? What should I be looking for?

• Windows clients unable to access Samba share on AD joined Linux box every 7 days

  - by Hassle2

  The problem: Every 7 days, 2 Windows Servers are unable to access a SMB/CIFS share. It will start working after a handful of hours. The environment: OpenFiler Linux box joined to 2003 AD Domain Foreground app on Win2003 server access the SMB/CIFS share with windows credentials Another process on Win2008 access the share via SQL Server with windows credentials The Samba version on the Linux box is 3.4.5. Security is set to ADS wbinfo and getent return back expected users and groups Does not look to be a double hop issue as it's always the 2 accounts, regardless of the calling user. There is a DNS entry in both forward and reverse lookup zone for the linux box The linux box's computer object in active directory shows that it was modified around/at the same time that the two clients started failing to access the share Trying to access the share via IP works when by name does not Rebooting the Windows server takes care of it (it's production and only restarted it once) Restarting smbd, winbind, nmbd had no effect Error in samba log for the client in question: smbd/sesssetup.c:342(reply_spnego_kerberos) Failed to verify incoming ticket with error NT_STATUS_LOGON_FAILURE! The Question: Does this look like the machine account password is changing (hence the AD object showing the updated modified date) or are the two windows clients unable to request a new ticket that works against this linux box?

• NIS user not being added to NIS group

  - by Brian

  I have set up a NIS server and several NIS clients. I have a user and a group on the NIS server like so: /etc/passwd: myself:x:5000:5000:,,,:/home/myself:/bin/bash /etc/group: fishy:x:3001:otheruser,etc,myself,moreppl I imported the users and groups on the NIS client by adding +:::::: to /etc/passwd and +::: to /etc/group. I can log in to the NIS client, but when I run groups, fishy is not listed. But getent group fishy shows that it was imported correctly and lists me as a member. And if I do sudo su - myself, then suddenly groups says I am in the group! I also had nscd installed, and the groups worked correctly for a while. It seemed like after being logged in for a while, I would silently be dropped out of the group. If I restarted nscd and logged in again, then the groups worked correctly...for a while. There are no UID or GID conflicts with local users or groups. Update: Contents of /etc/nsswitch.conf: passwd: compat group: compat shadow: compat hosts: files nis dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis aliases: nis files

• Streaming to PS3 with NAS and built-in dlna server?

  - by philt

  With consumer-grade hardware, is it possible to successfully stream 1080p mp4 videos to a PS3? I have a linksys router that can only do 10/100. The PS3 is wired to it with cat5e cable, and the PS3 itself supports gigabit ethernet. I would upgrade the router and get one that supports gigabit ethernet if it could handle streaming like this. It currently does work with minor jerkiness streaming from my mac to the PS3, but fast-forward/reverse and "goto" (equivalent of scene selection) take forever and/or fail completely. And streaming from my mac of course requires the mac to be on at all times. When I put the movies on an external USB drive and connect to the PS3 directly, it performs flawlessly. Fast forward and everything works great. So I was thinking about getting a NAS, but I don't know if any inexpensive NAS (i.e. Buffalo Linkstation Live, WD My Book World Edition, D-Link DNS-321, etc.) can actually deliver the performance necessary to do this, even with gigabit ethernet?

• ProCurve 1800 switch issue

  - by user98651

  I recently deployed ProCurve 1800-24G switches in place of some older ProCurve 2424M switches in my network. However, I'm having a serious problem with the switch connected to the router. It seems, every night when our Windows 2008 R2 server (off site) runs a backup to a iSCSI target (on site) [facilitated through a PPTP tunnel] the LAN loses connectivity with the router. To clarify, there is only one router which is connected to the switch affected by this problem. The only way to resolve the issue is to either reboot the router or pull the ethernet cable that goes to the router and plug it back in. During the outage, clients cannot receive DHCP requests, DNS requests, ping, or do anything else with the router in this state. Now, neither the switch or router are configured extensively and the issue only seems to have surfaced with the new switch in place. I have tried a number of things including replacing cables, rebooting and checking the switch configuration (it is literally as basic as you can get at this point-- flat LAN, no trunking). Interestingly, the router shows (accessed externally) no changes in configuration or status during this state but similarly cannot ping or access other hosts on the network. This issue occurs in different stages of backup (ie, different amounts transferred). I've also dumped packets from the switch into WireShark but cannot seem to find any anomaly yet (I'm looking at packets around the time the issue appeared and at the time when I reset the NIC). Any suggestions for what to look for? Ideas on what could be causing this? I'm seeing some transmit/receive errors on the NIC from both the router and switch side but nothing serious when compared to the total packet counts. I'm seriously doubting hardware at this point, as I have tried another switch, different cables, and a different NIC on the router.

• How to make Exchange 2003 non-authoritive

  - by Romski

  Background We are a small company with an internally hosted Exchange 2003. It receives email for 2 domains (the company was renamed a few years back). For the sake of argument, the domains are: oldname.com newname.com We have moved newname.com to a hosted exchange service, and our DNS record is correctly routing emails. Our internal server still receives email for oldname.com, although we have asked our hosting company to accept emails for that domain. Problem My problem is that emails generated internally from monitoring software, printer, etc. are being caught by our (defunct) internal server and being delivered to the old mailboxes. I believe that what is happening is that our internal exchange server considers itself to be the authoritive server for newname.com. I think it must be looking in active directory for a mailbox and delivering it internally without ever going outside. Attempt to fix I started to follow the article here: http://support.microsoft.com/kb/321721. I removed the SMTP recipient policy for newname.com, and added a dummy address and made it primary. I also answered yes for updating the associated emails. I then restarted the Microsoft Exchange Routing System and SMTP, but emails are still being routed internally. Is there a way to force the exchange server to route all emails for the domain newname.com to the new hosted service?

• Windows - Website unaccessible only on windows pcs in LAN

  - by DorentuZ

  For serveral days now, a website isn't accessible on a single pc in the LAN. On the other pc's, it works just fine. And it's just a single website that's not accessible as far as I know of. The website generates a timeout on every single web browser I've tried (IE8, Firefox and Chrome). However, traceroute, nmap and telnet all work just fine. I've even tried multiple user accounts and safe mode, but that didn't work either. As a side note: using a linux live cd did work and I could access the website without any problems. The hosts file is the windows default, the ip- and dns settings on the network adapter normal as well. No strange processes are running and no viruses found. According to tcpview and netstat there are connections to the domain, but every request in the browser results in a timeout.. Any idea what's happening? Update: All of the computers on the network running Windows (any version) are showing this problem now. The website is still working under linux and mac osx. So, it has to be related to some kind of windows update (although I haven't installed any on one computer in the past week, which I've set to do manual updates only)..

• SBS 2003 stops to respond often due to limited memory

  - by Sanoj

  I have a Windows SBS 2003 Std that regularly stops to respond (crashes), in about every 20th day. The only thing I can see in the logs (the one that are mailed to the administrator) is that used memory increases with about 30MB/day. The process that uses more and more memory is sqlservr. We don't have much installed on the server; a Point-Of-Sale-system that uses Pervasive SQL as database and an Accounting application. We just have 2GB of RAM and I could upgrade to 4GB but I think that this just delay the problem. When the server stops to respond, the screen saver cannot be deactivated, no DNS-look-ups is working so the client's can't access Internet. And applications on the server do not reply. And we have to press the power-button to restart the server. For the moment it has an uptime of 19 days and have 2 345MB in memory use (idle) and sqlservr is using 819 MB. So I guess it will crash soon. Is there any solution to this problem? Could I limit sqlservr to some memory?

• Moving Farm to co-location hosting - network settings requirements

  - by Saariko

  I am moving my farm (2 Dell's R620) to a co-location hosting service. I am trying to figure out the secure way to have my network settings The requirements are: VM1 is the working HOST, includes: esxi 5.1, vSphere, 4 clients (w2008r2 all) VM2 has esxi 5.1 installed, and a single machine with Veeam Backup and copy 6.5 - keeping a copy of VM1 clients on the VM2 internal storage (this solution is due to a very small budget - in case of failure on Host 1 - can redirect IP's) Only 2 VM clients require network address and access from the WWAN - ISP provides IP's range for them (with Gateway and DNS) I need connection to the iDrac's from my office (option to create a VPN-SSL tunnel) Connection to the vSphere appliances I want to be able to RDP to the VM clients The current configuration is that each host has the iDrac dedicated nic connected , and another (NIC #1) connected - with a static IP on 192.168.3.x The iDrac's have a static IP from the same network range (19.168.3.x) It will look something like this: My thoughts: On NIC#2 of both hosts I will connected a crossed cable I will give each VM clients that needs internet access a 2ndry VM network with the assigned IP from the ISP open only to web - can not access from the My Question: Should I give IP's (external) to the machines who DO NOT require WWAN Access? - I can't see a way to RDP to them directly if not. Should I use the crossed cable? or just plug NIC #2 to the switch? Will this setup even work? What do I need to verify? What Virtual nic's and/or switches should I create on the Hosts?

• Default Gateway solution on NAT'd network (best options)

  - by kwiksand

  I've recently changed a network from a bunch of machines exposed to the net on a network to a more security conscious Firewall-fronted network with a DMZ for public services. Everything's mostly working perfectly now, but I've got the old problem of NAT Loopback where a machine within the LAN wants to access a public service via the public/external IP. I've solved this problem previously in a small/SOHO environment simply using NAT loopback features of the router in use or a simple iptables rule to do the same, but I want to make sure I make the most resilient choice with the least concern. It seems I can: Use iptables as I've said to DNAT and MASQUERADE the change source/destination so the connection works correctly i.e iptables -A PREROUTING -t nat -d ip.of.eth0.here -p tcp --dport 8080 -j DNAT --to 192.168.0.201:8080 iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -p tcp --dport 8080 -d 192.168.0.201 -j MASQUERADE Use split DNS, with internal mappings for public IP's Potentially do some route nastyness by setting the Default Gateway to use a different externally exposed IP to then come back in the public route (messy) Someone mentioned putting the Default Gateway within the DMZ as well (on serverfault), but I can't find the post again. I'm sure this is a common issue for many with NAT'd networks, but I've not really seen the perfect solve all when it comes to fixing this problem. What is your opinion?
