• Proper web server setup

  - by DMin

  I just got myself a slicehost basic slice to play around with so I can learn how to setup web-servers. I have Ubuntu 10.04.2 installed on the server. I was able to successfully get the server up and running from scratch, these were the things I did - following this tutorial. I know this is probably just a starters tutorial, so, I was wondering if you guys can tell me what you like to do while setting up production servers. These are the steps that were followed : Update and Upgrade Ubuntu sudo apt-get install apache2 php5-mysql libapache2-mod-php5 mysql-server Backup a copy of and edit apache2.conf Set : 'ServerTokens Full' to 'ServerTokens Prod''ServerSignature On' to 'ServerSignature Off' Backup php.ini and then Change “expose_php = On” to “expose_php = Off” Restart Apache Install Shorewall firewall Configure Shorewall to only accept HTTP and SSH connections(in the rules file) Enable shorewall on startup Add the website to the server : sudo usermod -g www-data root sudo chown -R www-data:www-data /var/www sudo chmod -R 775 /var/www I want make this CommunityWiki but can't seem to find the option to do it. Please feel free to add any feedback on the processes and things I am doing right/wrong. Much appriciated, thanks! :)

• Secure data from a server to a workstation using jumper hosts

  - by apalsson

  Hello. I have a WWW-server, my problem is that the content is sensitive and should not be accessible for people without proper credentials. How can I improve the ease of use but still maintain security following scenario; The Server is accessed through a "jumper host", i.e. the client connects to the jumper using VPN-connection and uses RemoteDesktop to access the jumper. From the jumper he uses RemoteDesktop again to access the Server. Finally on the Server the user can access content using a WWW-browser. All the way from the VPN-client to the WWW-browser requires authentication using a SmartCard-token. This seems quite secure to me. Content only gets mirrored on the RemoteDesktop between Server and jumper, no cached files to worry about. Connection between jumper and client is protected using VPN(ssl), so no eavesdropping. But it is quite cumbersome for the clients with many steps and connections to open. :( So, how can I improve the user experience accessing my server without compromising security? Thanks.

• Virtual Machine Network Services causes networking problems in Vista Enterprise 64 bit install

  - by Bill

  I have a Quad-core/8GB Vista Enterprise 64-bit (SP2) installation on which I installed Virtual PC 2007. I have a problem that is opposite of all that I found searching around the Internet--everybody has problems making network connections from their guest VM. When Virtual Machine Network Services is enabled in the protocol stack for my network card across a reboot, it causes access problems to the network. The amount of time to login in using a domain credentialed account is upwards of 3 minutes, then after reaching the desktop the network and sharing center shows that my connection to the domain is unauthenticated. Disabling and re-enabling the Virtual Machine Network Services (uncheck in network properties/apply/recheck/apply) fixes the problem. And as long as I have the VMNS disabled when I shutdown the restart runs smoothly. I just have to remember to enable after login and disable before shutdown. I have un-installed and re-installed Virtual PC 2007 multiple times with restarts between. The install consists of the SP1 + a KB patch for guest resolution fix. Any help would be greatly appreciated. Some additional information... At one point during my hairpulling and teethgnashing with this, I tried to ping my primary DC and observed some weird responses: (Our DC is 10.10.10.25, my dynamic IP was 10.10.10.203) Reply from 10.10.10.203, Destination host unreachable. Request timed out. Reply from 10.10.10.25: ... This is not consistently repeatable, but thought it might strike a chord with someone.

• Network connection keeps dropping - bad hardware?

  - by Bill Sambrone

  Hello all, I've into a bit of a wall with a client of mine. In an office of 20 people, he is the only one who experiences broken connections to his mapped network drives. I have everyone set up with about 6 mapped drives, all pointing to the same server (no DFS), and everyone else can access them lightning fast. The environment consists of a mix of Windows 7 and XP machines, all 32-bit. The server holding the data everyone is mapping to is running on Server 2008 R2, and is a domain controller. We recently swapped out their old 10/100 switch for a shiny new Dell PowerConnect gigabit switch. We have also replaced an old dying Sonicwall with a shiny new one. Everything is running on an ESX host except for the DC, where everyone is getting data from. In my client's office, we have done the following: Swapped out his computer (Win7 and XP box) Swapped out the desktop switch in his office Removed the desktop switch in his office Changed out the network cable going to the wall Ran 'net config server /autodisconnect:-1' on the server Disabled remote differential compression on his current Win7 box When we swapped out his network cable, everything seemed fine for about 4 days. Normally I would get a phone call a couple times per day letting me know that Outlook has crashed (there is a 9GB PST living on the server he is always connected to), or that his software he is running from his L drive has crashed. I almost thought I had this solved, but after we rebooted the DC the other night he all of a sudden couldn't stay connected to his mapped network drives for more than 10 minutes. When I ran 'net use' from the command prompt, it listed all the network drives where were randomly in a state of 'OK', 'Disconnected', or 'Reconnecting'. What else should I try? Maybe there is bad wiring in the wall, patch panel, or a bad port in the new switch I have in the server room?

• HP Photosmart C4780 printer/scanner breaks netgear WNDR3700v3 router on connection

  - by CodeJunkie

  A few months ago, we upgraded our Netgear router's firmware. Immediately, we started having trouble connecting to the internet. Each time this problem would happen, every device in the house would stop being able to make new connections to the internet. For example, you couldn't open new pages in the browser, but if Skype was running when the problem happened, you could keep talking to people. The only solution to this problem seemed to be resetting the router to factory defaults. Eventually, we solved this problem by just downgrading the router firmware. A while later, we got a new Netgear router. Almost right away, the new router started having exactly the same problems as the old one did on current firmware. The network connection would stay active and the computer would say it had an internet connection, but you couldn't do anything online except for using Skype. We eventually figured out that this happens every time our HP printer gets onto the network. Any time the printer gets onto the wireless network, the whole network stops connecting to the internet almost completely. The only thing that will fix it at that point is to reset the router to factory specs, and unplug the printer so it can't get back onto the network. The Netgear router has the latest version of the firmware, but the printer/scanner is very old. It looks to me like this problem is probably a result of a firmware conflict between the printer and the router, but I'm not sure how to fix that problem. Here's some additional information: Printer: HP Photosmart C4780 Router: WNDR3700v3 Router firmware: V1.0.0.22_1.0.17 (Stock, up to date firmware) Why would the printer getting on the network cause the router to not be able to access the internet correctly until it was reset? What can be done to allow the printer to be on the network without breaking the network for all other devices? Edit: One other thing that happens during this internet problem is that multiple computers in the house display an "IP conflict" message repeatedly, and extremely frequently (as often as every five to ten minutes, and every time a connection to the wireless is made).

• Connect by Wifi to Sql Server from another computer

  - by Bronzato

  I try to connect by Wifi to Sql Server with Sql Server Management Studio from another computer but it failed. I have a computer with Windows Seven & Sql Server 2008 (lets say the server computer). Next to it, I have a fresh installed computer with Windows Seven & Sql Server Management Studio (let's say the client computer). What I do on the server computer: configure firewall by enabling port 1433 enabled network protocols (TCP/IP) inside Sql Server Configuration Manager checked "Allow remote connections to this server" on server properties in Sql Server Management. started Sql Server Browser restarted services (Sql Server Browser is stopped but I think it is not neccessary, isn't it?) Next, I successfully tested a ping on the port 1433 from my client computer with a tool named tcping (ex: tcping 192.168.1.4 1433). But I still cannot connect from my client computer to Sql Server on my other computer. Ok, something new on this problem: until now, I successfully connected to my "server computer" with Management Studio. What I do is typing the computer name in the server name field in the connection window of Management Studio. My previous (failed) attempt was to type the computer name followed by the instance of sql server (ex: COMPUTER_NAME\SQL2008). I don't know why I only have to type the computer name... Nevermind. Now my new challenge is to succeed connecting my VB6 application to this remote database located on my "computer server". I have a connection string for this but it failed to connect. Here is my connection string: "Provider=SQLOLEDB.1;Password=mypassword;User ID=sa;Initial Catalog=TPB;Data Source=THIERRY-HP\SQL2008" Any idea what's wrong? Thanks

• What to look for in a switch with LAN/WAN verses an iSCSI SAN?

  - by Luke

  I'm setting up a VMWare ESXi 5 environment with 3 server nodes. Dell recommended 2x Force10 S60 switches shared (iSCSI SAN, LAN/WAN). The S60 switches are extremely powerful. They have 1.25 GB of buffer cache, < 9us latency. But they are very expensive (online price ~$15k per switch, actual quote a little less). I've been told that "by the book" you should at least have 2 internal switches for SAN, and 2 switches for LAN/WAN (each with a redundant). I know some of the pros and cons of each approach. What I'm wondering is, would it be more cost effective to disjoin the SAN from LAN with less expensive switches? The answer to this question highlights what I should be looking for in a switch for the SAN. What should I be looking for in a LAN/WAN switch, in comparison to the SAN? With the above linked question for the SAN: How is buffer latency measured? When you see 36 MB of buffer cache, is that shared or per port? So 36 MB would be 768kb or 36MB per port? With 3 to 6 servers how much buffer cache do you really need? What else should I be looking at? Our application will be heavily using HTML5 websockets (high number of persistent connections). The amount of data being sent is small; Data sent between client <- server isn't broadcasted (not a chat/IM service). We will be doing some database reporting too (csv export, sums, some joins). We are a small business and on a budget. We'd probably only be able to spend no more than $20k on switches total (2 or 4).

• fwbuilder/iptables manually scripted + autogenerated rules at startup?

  - by Jakobud

  Fedora 11 Our previous IT-guy setup iptable rules on our firewall in a way that is confusing me and he didn't document any of it. I was hoping someone could help me make some sense of it. The iptables service is obviously starting at startup, but the /etc/sysconfig/iptables file was untouched (default values). I found in /etc/rc.local he was doing this: # We have multiple ISP connections on our network. # The following is about 50+ rules to route incoming and outgoing # information. For example, certain internal hosts are specified here # to use ISP A connection while everyone else on the network uses # ISP B connection when access the internet. ip rule add from 99.99.99.99 table Whatever_0 ip rule add from 99.99.99.98 table Whatever_0 ip rule add from 99.99.99.97 table Whatever_0 ip rule add from 99.99.99.96 table Whatever_0 ip rule add from 99.99.99.95 table Whatever_0 ip rule add from 192.168.1.103 table ISB_A ip rule add from 192.168.1.105 table ISB_A ip route add 192.168.0.0/24 dev eth0 table ISB_B # etc... and then near the end of the file, AFTER all the ip rules he just declared, he has this: /root/fw/firewall-rules.fw He's executing the firewall rules file that was auto-generated by fwbuilder. Some questions Why is he declaring all these ip rules in rc.local instead of declaring them in fwbuilder like all the other rules? Any advantage or necessity to this? Or is this just a poorly organized way to implement firewall rules? Why is he declaring ip rules BEFORE executing the fwbuilder script? I would assume that one of the first things the fwbuilder script does it get rid of any existing rules before declaring all the new ones. Am I wrong about this? If that was the case, the fwbuilder script would basically just delete all the ip rules that were defined in rc.local. Does this make any sense? Why is he executing all this stuff at startup in rc.local instead of just using iptables-save to keep the firewall settings at /etc/sysconfig/iptables that will get implemented at runtime?

• Nginx + PHP-FPM Too Many Resources

  - by user3393046

  My Server has the following Specs CPU: 6 Cores Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz RAM: 32 GB I have a problem with nginx+php-fpm. They are taking too many resources for an unknown reason. Even if i restart the nginx + php-fpm the start up processes will use many resources. My nginx Config is the following: user nginx; worker_processes auto; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; worker_rlimit_nofile 300000; events { worker_connections 6000; use epoll; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; } My php-fpm pool config is the following [www] user = nginx group = nginx listen = /var/run/php5-fpm.sock listen.owner = nginx listen.group = nginx listen.allowed_clients = 127.0.0.1 pm = ondemand pm.max_children = 1500; pm.process_idle_timeout = 5; chdir = / security.limit_extensions = .php I'm using on pm.ondemand since my website has to support many concurrent connections at the same time and i was unable to to it with dynamic/static. I guess this isnt the problem because as i said earlier when i restart nginx+php-fpm at the same time, they are taking too much resources without any request. Here is the screenshot with the CPU Usage http://s28.postimg.org/v54q25zod/Untitled.png

• Under what conditions will sendmail try to immediately resend a message instead of waiting for the standard requeue interval?

  - by Mike B

  CentOS 5.8 | Sendmail 8.14.4 I used to think that if SendMail experienced a temporary (400-class) error during delivery, it would place the message in a deferred queue (e.g. /var/spool/mqueue) and retry an hour later. For the most part, that appears to be the case. But every now and then, I'll notice log entries like this (email/domains renamed to protect the innocent :-) ) : Dec 5 01:43:03 foobox-out sendmail [11078]: qBE3l7js123022: to=<[email protected]>, delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=124588, relay=exbox.foo.com.

[10.10.10.10], dsn=2.0.0, stat=Sent (<[email protected]> Queued mail for delivery) Why did Sendmail try again just 10 minutes after the first attempt and then wait another hour before trying again? If this is expected behavior, what scenarios will cause this faster requeue interval to occur?

• Encrypted WiFi with no password?

  - by Ian Boyd

  Is there any standard that allows a WiFi connection to be encrypted, but not require a password? i know that (old, weak) WEP, and newer WPA/WPA2 require a password (i.e. shared secret). Meanwhile my own wireless connections are "open", and therefore unencrypted. There is no technical reason why i can't have an encrypted link that doesn't require the user to enter any password. Such technology exists today (see public key encryption and HTTPS). But does such a standard exist for WiFi? Note: i only want to protect communications, not limit internet access. i get the sense that no such standard exists (since i'm pretty capable with Google), but i'd like it confirmed. Claraification: i want to protect communcations, not limit internet access. That means users are not required to have a password (or its moral equivalent). This means users are not required: to know a password to know a passphrase to enter a CAPTCHA to draw a secret to have a key fob to know a PIN to use a pre-shared key have a pre-shared file to possess a certificate In other words: it has the same accessibility as before, but is now encrypted.

• Windows 7 Automatically Connecting To Unsecured Wireless Networks On Startup

  - by Xtend

  Most of the questions on this topic related to folks connecting to somebody else's wireless network when their own was available and could remedy the situation by going to their connections and unchecking the "connect automatically" box. See this: " Avoid automatically connecting to wireless network on windows 7 " as an example. In my situation, I've noticed that Win 7 will automatically connect to any unsecured wifi network - even if I have never connected to it in the past. If I am traveling and boot Win 7, it will start and connect to what appears to be the best signaled unsecured network without prompting me for confirmation (note: in the above link, "Naveen" seems to have same problem). Obviously, that is a security concern to me. Further, when I open "Network and Sharing" and "Manage wireless networks" the network is not displayed (probably because I labelled it a public network). Again, these are new, never connected with before, wireless networks. I always promptly disconnect from them but don't want to have to be on constant guard for an auto connection to a malicious network. This began about a month ago, as I recall, Win 7 did not behave like this in the past, I didn't monkey with wifi settings, and don't use a 3rd party connection manager. I did have to download some internet security certificates for army website access but I don't think that should mess with network settings. Any ideas how I can tell Win7 cease automatically connecting to networks or, at least, to prompt me for a confirmation before connecting?

• Ubuntu 10.10 - PC shutdown before boot shortly after BIOS loads

  - by clem

  Since installing Ubuntu 10.10 from Karmic I've started getting problems with starting up the PC. I've done a complete wipe (Boot and Nuke) of the hard drive and reinstalled Ubuntu 10.10 but the problem still occurs. There is no dual boot on the PC, just Ubuntu. Here is the problem: Each morning, when I turn the PC on from being off overnight, the PC starts up and loads the BIOS. I get the following message Verifying DMI Pool Data... K8 NPT Data Change...Update New Data to DMI!....... Then poof the computer shuts off. However, after switching the computer back on around 6 or 7 times after it's turned itself off, it will eventually boot up without any problem. Also, once up and running for a while, I can shutdown and restart the PC first time, without any issues. I have also noticed a problem with the USB mouse being recognised and once I finally get the computer booted up, I need to unplug and then plug the mouse back in to get it working. I've opened the PC up and checked the connections (cables, cards and memory) and it all seems fine. The main issue with troubleshooting this problem is I cannot test any suggestions or fixes until the next morning because once the computer is up and running it will remain so! I do not leave the computer on overnight to save energy. So.. Is this a hardware / boot software issue? This is a very odd problem and I have googled to no avail. Any suggestions?

• Two monitors with Mac Mini - one displays black despite receiving a signal

  - by alex

  My Mac Mini outputs to my two new monitors - Dell U2311Hs. The LED on the bezel displays blue when receiving a signal, or yellow otherwise. Both screens are displaying blue. It also seems my Mini can see both of them... However, one of them is black. It just displays black, but appears to be receiving a signal (when I turn the Mac off, it then displays No Signal). To make things weirder, on startup, the boot up (white with Apple logo) appears on the right monitor (the one that now displays black). Occasionally, it flickers up on the black screen for 1 second. I have tried Detect Displays. It appears to do nothing. I'm also running a dual monitor KVM. Video connections are DVI-D. How can I fix this situation? Thanks. Update This is the weirdest thing - I used the DVI-D cable that came with the KVM and it seems to have fixed it - I didn't both because it looks identical to any other DVI cable (in form an pin out). So, I will accept an answer if someone can tell me what may be the difference in these cables?

• Multiple logins with pam_mount means multiple (redundant) mounts ...

  - by Jamie

  I've configured pam_mount.so to automagically mount a cifs share when users login; the problem is if a user logs into multiple times simultaneously, the mount command is repeated multiple times. This so far isn't a problem but it's messy when you look at the output of a mount command. # mount /dev/sda1 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) none on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) none on /dev type devtmpfs (rw,mode=0755) none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) none on /dev/shm type tmpfs (rw,nosuid,nodev) none on /var/run type tmpfs (rw,nosuid,mode=0755) none on /var/lock type tmpfs (rw,noexec,nosuid,nodev) none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) //srv1/UserShares/jrisk on /home/jrisk type cifs (rw,mand) //srv1/UserShares/jrisk on /home/jrisk type cifs (rw,mand) //srv1/UserShares/jrisk on /home/jrisk type cifs (rw,mand) I'm assuming I need to fiddle with either the pam.d/common-auth file or pam_mount.conf.xml to accomplish this. How can I instruct pam_mount.so to avoid duplicate mountings?

• Apache2: Limit simultaneous requests & throttle bandwidth per IP/client?

  - by xentek

  I want to limit simultaneous requests & throttle bandwidth per IP/Client on a single apache vhost. In other words, I want to ensure that this site, which hosts large media files, doesn't get hammered by someone trying to download everything all at once (just happened the other night). I'd like to limit the outgoing transfer speed overall for this site, as well as limit the number of connections a single IP can make to the server to a sane default (i.e. within normal browser limits for multiple requests so page loads aren't effected too much). Bonus points if I can actually scope it to file types (i.e. leave web files alone, but apply these rules to just the media files). We're running Ubuntu 9.04 on all the servers, and have two apache/php servers being load balanced via Round Robin by a squid proxy server. MySQL is running on its own box as well. We've got plenty of bandwidth to give them, so I don't really want overall caps, but just want to throttle the amount of memory/CPU it takes to serve this site. There other sites on these servers that we don't want to apply these rules too, just want to keep this one from hogging all the resources. Let me know if you need more info! Thanks in advance for your suggestions!

• Internet Explorer not working after establishing a SSTP VPN connection

  - by Massimo

  I have a problem which is constantly appearing on each Windows 7 computer I'm using, whenever I establish a SSTP VPN connection to a ForeFront TMG 2010 firewall; it only happens with SSTP connections, not PPTP/L2TP ones. The problem appears only if using a proxy server for Internet access; it doesn't happen when directly accessing the Internet (with or without NAT). It doesn't seem to depend on a specific proxy software being used (I've seen it happening with various ones). The problem is: as soon as I start the VPN connection, Internet Explorer can't access anything anymore. I'm not using the VPN connection as a default gateway, and I can succesfully ping the proxy server after the VPN connection is esatablished (and even telnet to its 8080 TCP port), so this is definitely not a routing problem. Also, the problem is specifically related to Internet Explorer: while it seems not able to connect to any site, other programs (such as FireFox) have no problem accessing the Internet through the same proxy. This behaviour can be easily reproduced on any Windows 7 computer (the service pack and patch level doesn't seem to matter at all). Have IE connect through a proxy, establish a SSTP VPN connection... and IE will just not work anymore until the VPN connection is dropped.

• Internet Problem: Wireless connected but no connection to internet

  - by Josh K

  Hey i have a interesting network setup on a laptop here and for some reason the internet isnt working. I am connected to a secure network via wireless router and taskbar says i am connected and with good signal strength but in my internet browser i cant connect to any websites, the error is: This webpage is not available. (Chrome) I am using Chrome, but websites dont work on IE either. Heres a little background on the setup i have. I have a Ethernet connected to the laptop with a static ip, and then i have the wireless setup with DHCP enabled. I am using the ethernet to connect to the network (for remote desktop) but the wireless for internet (to avoid the network firewalls). this set up has worked fine for a few months, but i cant figure out what is going on now. Might be worth it to note it is a Lenovo Thinkpad and i just uninstalled ThinkVantage Access Connections (as it was giving me ample problems prior to this one, which i consider a step up) Tried repairing connection as well, let me know if you guys have any ideas please! EDIT: Solved-Dead Modem in the server room.... Sorry guys didn't have access to that myself

• mod_rpaf problems with Nginx front, Apache back-end after Ubuntu upgrade

  - by Kenn

  I'm running an Nginx front-end for static files, and proxying to an Apache backend for PHP and Passenger, using Apache's mod_rpaf to set the correct remote IP address on the backend. Everything worked fine until I upgraded to Ubuntu 12.04 (Precise). Now Apache reports all connections coming from 127.0.0.1. Here's the relevant configuration. Nothing here changed with the upgrade. Nginx: proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; mod_rpaf: <IfModule mod_rpaf.c> RPAFenable On RPAFsethostname On RPAFproxy_ips 127.0.0.1 ::1 RPAFheader X-Forwarded-For </IfModule> I'm using %{X-Forwarded-For}i in my Apache LogFormat directive and the access logs are showing the correct remote address, so I know Nginx is passing the address along properly. In a phpinfo() test, HTTP_X_FORWARDED_FOR is showing the correct remote address, but REMOTE_ADDR is 127.0.0.1. This is reflected in PHP applications as well, such as WordPress comments. I've tried switching Nginx and mod_rpaf to X-Real-IP with no effect. Did something change that I missed? Relevant version info, everything installed from the Ubuntu repository: Nginx 1.1.19 Apache 2.2.22 mod_rpaf 0.6

• High speed network configuration

  - by Peter M

  Sorry if this seems to be a stupid question, I'm not sure how to specify what I want to know when checking google. I will have 2 or 3 devices pumping out data on a 100Base-T port. The combined data rate of all devices is about 15KB/S which exceeds the optimal 100Base-T channel capacity (12KB/S), but well within the realms of a 1000Base-T connection. Each device will be sending a burst of data in the form of an FTP transfer to a common, single host computer in a sequential manner ie: Device A establishes FTP connection and transfers data Device B establishes FTP connection and transfers data Device C establishes FTP connection and transfers data It may be that the A&B, B&C and C&A transfers overlap in the time domain to some extent. There will be minimal traffic going back from the computer to each device (in general what ever is needed to support the FTP transfers), and the network will be dedicated to transferring data between these devices and the host computer. Is it possible to use a switch to combine the multiple incoming 100Base-T streams into a single outgoing 1000Base-T stream? if so what features in a switch should I be looking for? Or would it be better to have 3 physical point-to-point 100Base-T dedicated connections between each device and the host computer? (thus having at least 3 physical Ethernet interfaces on that computer) Note that I can't change the interface on the devices, but I am free to choose the network and host computer configuration. Thanks for you help Peter

• Implementing an isolated guest WLAN via IPSec VPN on Windows

  - by sysadmin1138

  We are attempting to set up a guest WLAN network that is isolated from the rest of our network. This is proving difficult due to a couple of technical reasons. My first choice was to use a separate VLAN, on which our Firewall's handy WLAN port would handle DHCP, DNS and the network isolation we need. Unfortunately, due to the fact that our main office and our Internet connection itself are in different locations connected by way of a Metro Ethernet connection, I'm at the mercy of our ISP for VLAN transit. They won't pass a second VLAN between our two sites. And my hardware doesn't support 802.1ad "Q-in-Q", which would also solve this problem. So I can't use the VLAN method for isolation. At least not without spending money. As our Firewall can handle IPSec site-to-site VPN connections, I hope it is possible to connect a Server 2008R2 (standard) server I have in the office location to the WLAN and provide gateway services to the firewall. Thusly: Unfortunately, I don't know if it is possible to connect the two this way. The firewall has a pretty flexible IPSec/L2TP implementation (I've used it to connect iPads in the wild), but is neither Kerberized or supports NTLM. The Connection Security Rules view on the Windows server seems to get close to what I think needs to be done, but I'm failing on figuring out how to get it to do what I need it to do. Is this even possible, or do I need to pursue alternate solution?
