  • iptables question

    - by RubyFreak
    i have a small network, with one valid IP and a firewall with 3 network interfaces (LAN, WAN, DMZ). I want to enable PAT on this valid IP to redirect http traffic to a server in my DMZ. (done) I want to enable MASQ on this ip from traffic that comes from my LAN (done) I want from my LAN as well to access my http server at DMZ. (partially) Question: in the above scenario, i cannot from my LAN, to access my http server in the DMZ, since it has the IP used by the MASQ (the only valid ip that i have). What would be the best option to solve this problem? network interfaces: eth0 (WAN) eth1 (DMZ) eth2 (LAN) /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE /sbin/iptables -A FORWARD --o eth1 -d 2.2.2.2 -p tcp --dport 80 -j ACCEPT /sbin/iptables -t nat -A PREROUTING -i eth0 -d 1.1.1.1 -p tcp --dport 80 -j DNAT --to 2.2.2.2 /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT /sbin/iptables -A FORWARD -i eth2 -o eth0 -j ACCEPT

  • dd-wrt switch for PfSense

    - by Kmao
    I currently have eth2 on my pfsense set up, and configured as 192.168.1.1, it has dhcp setup with allocation being 192.168.1.10 - 192.168.1.245. On my dd-wrt box, i disabled the WAN, and set it to act as a port for the switch. I disabled dhcp, dnsmasq, spi firewall, Wlan0 and set a static IP for the router being 192.168.1.10 Pfsense is plugged into lan0 and pc plugged into lan1 (wan port is empty) I have followed a few different guides, but i can't seem to get my router to act as a switch. Anyone have success using DD-WRT as a switch while using pfsense as your dhcp/dns/gateway. Any advice would help :)

  • unreachable subnet in one direction

    - by Carl Michaud
    I'm unable to route traffic to a subnet in my home. Here's my topology: INET <- Router A <- Router B <- WIFI AP where: Router A - ARRIS TG862G/CT (from comcast) - WAN DHCP, LAN 10.0.0.99 Router B - Linksys WRT400N with DD-WRT - WAN 10.0.0.12 , LAN 10.0.1.1 I was able to use DD-WRT to configure a static route for the 10.0.1.x network back to the 10.0.0.x network. But I'm not sure if i can do the reverse on the ARRIS router and was looking for suggestions on how to fix that. I've set things up this wasy because I am using OpenDNS to mange internet content for my kids and of course I wasn't able to configure DNS to my liking on Router A either. So at present I'm using Router A on 10.0.0.x to provide a private unfiltered WIFI AP (no ssid broadcast) that I use for netflix only and then I use router B to provide a filtered WIFI AP for the rest of my WIFI devices on 10.0.1.x. However I would like to be able to connect to my 10.0.1.x devices from the internet via dynamic dns; but I can't see anything behind router B this way. Thoughts?

  • Process for migrating Dropbox to SpiderOak

    - by Marcel Janus
    I want to move my data from dropbox to SpiderOak. I have 3 computers running dropbox. But I have a poor WAN connection with very limited upload bandwidth. So I thought I do as first step install the dropbox client on my server on the internet an download there my data from dropbox. Then after this I upload/backup my data from this server with a broadband connection to SpiderOak. After the backup is completed I setup the sync between my 3 computers so that they will not have to upload the data again. Will this process will work so that I don't have to upload my data again over my WAN connection at home?

  • How can I setup a Firewall without NAT?

    - by SRobertJames
    We have 16 IP addresses from our ISP, and are setting up a SonicWall Firewall. I'd like to have the SonicWall do NAT for the LAN, but act as a firewall only (no NAT) for the servers which are using some of the 16 addresses. How do I set this up? If I set the WAN's subnet to include the 16 IPs, the SonicWall won't route the traffic to the LAN interface. Should I set the WAN subnet to only include the ones we are dedicating for NAT, and then keep the others on the LAN? Related point: How can I set multiple IP addresses for a SonicWall LAN interface?

  • Disable ALTQ for internal network traffic

    - by javanix
    I currently have a FreeBSD 8.2 media server set up on my LAN that I use to stream my music from. I also have an SSH login that I use to do file transfers to and from this server remotely. I would like to set up ALTQ (and have gotten this working) to limit my outgoing bandwidth from the server for SSH traffic. However, configuring ALTQ this way is also limiting my internal traffic (and thus interfering with my music streaming) since I am only using a single network interface. Can anyone show me how I would use PF and ALTQ to limit outgoing WAN traffic while allowing all internal LAN traffic to go through unhindered? ext_if="eth0" int_if="eth0" altq on eth0 cbq bandwidth 1Mb queue { std, ssh } queue std bandwidth 80% cbq(default) queue ssh bandwidth 20% cbq(ecn) pass out on eth0 proto tcp to port 22 queue ssh eth0 is my LAN interface, my total WAN bandwidth on my cable connection is 1Mb/s, and my internal network is 10/100.

  • How to setup an Openvpn server with two gateways to internet

    - by fourat
    I have an openvpn server behind two wan interfaces: eth1 and eth2 where eth1 is the default gw and eth2 is where openvpn binds to. The problems my ovpn server is replying back to ovpn client via the default gw (through eth1) and the tcp negociation is lost before establishing any tunnel. Here's what's happening: wan client -----> eth2 ----> openvpn -----> eth1 ----> lost and not delivered back to client Is there a way to tell ovpn to stick on eth2 and consider it for all traffic ?

  • /etc/hosts file for a multi-homed, multi-domain machine?

    - by threecheeseopera
    I have a server (debian) with two network interfaces that I would like to host multiple services and domains on; it is not entirely clear to me how the hosts file should be set up. Example: eth0, bound to WAN interface 1.2.3.4: mail.example.com www.example.com eth0:1, bound to WAN interface 1.2.3.5: www.other-domain.com eth1, bound to LAN 192.168.1.123: some-clever-hostname What should my hosts file look like? (including localhost,localhost.localdomain, etc.) Should I use DNS for some of these entries? Which ones? Thanks!

  • SQL 2008 R2 Mirroring Issue

    - by CWL
    Windows 2008 R2 with SQL 2008 R2 - Using Mirroring of a Database across the WAN in a HA setup with one witness. One issue I am having is during a failure (ever so often) the system fails over or tries, but leaves both databases in a Restoring State. My guess is the failover issue happens when there is a WAN bouncing and the systems get confused. The usual fix is to reboot the sql servers. Has anyone seen this type of failure? While this does not happen often it does causes an issue and concern with HA not being trusted fully.

  • Is AMQP suitable as both an intra and inter-machine software bus?

    - by Bwooce
    I'm trying to get my head around AMQP. It looks great for inter-machine (cluster, LAN, WAN) communication between applications but I'm not sure if it is suitable (in architectural, and current implementation terms) for use as a software bus within one machine. Would it be worth pulling out a current high performance message passing framework to replace it with AMQP, or is this falling into the same trap as RPC by blurring the distinction between local and non-local communication? I'm also wary of the performance impacts of using a WAN technology for intra-machine communications, although this may be more of an implementation concern than architecture. War stories would be appreciated.

  • How can I force a subscriber to be synchronized from a local snapshot?

    - by Brian
    Hello, I have a SQL 2005 server replicating(merge\push) to SQL 2005 and SQL 2000 servers. I have multiple subscribers spread througout the United states. I have set , @snapshot_in_defaultfolder = N'false', @alt_snapshot_folder = N'c:\snapshots\Merge\' (sample location). I take the snapshot from the publisher that is in the same location, 'c:\snapshots\Merge\', and copy it to the subscribers. I wanted to avoid applying the snapshot over the WAN but from the performance I am getting the synchronization is going over the WAN. Does anybody have any ideas how to make sure that I am using the local copy of the snapshot and not the copy at the publisher? Thanks

  • Pfsense 2.1 OpenVPN can't reach servers on the LAN

    - by Lucas Kauffman
    I have a small network set up like this: I have a Pfsense for connecting my servers to the WAN, they are using NAT from the LAN - WAN. I have an OpenVPN server using TAP to allow remote workers to be put on the same LAN network as the servers. They connect through the WAN IP to the OVPN interface. The LAN interface also servers as the gateway for the servers to get internet connection and has an IP of 10.25.255.254 The OVPN Interface and the LAN interface are bridged in BR0 Server A has an IP of 10.25.255.1 and is able to connect the internet Client A is connecting through the VPN and is assigned an IP address on its TAP interface of 10.25.24.1 (I reserved a /24 within the 10.25.0.0/16 for VPN clients) Firewall currently allows any-any connection OVPN towards LAN and vice versa Currently when I connect, all routes seem fine on the client side: Destination Gateway Genmask Flags Metric Ref Use Iface 300.300.300.300 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.25.0.0 10.25.255.254 255.255.0.0 UG 0 0 0 tap0 10.25.0.0 0.0.0.0 255.255.0.0 U 0 0 0 tap0 0.0.0.0 300.300.300.300 0.0.0.0 UG 0 0 0 eth0 I can ping the LAN interface: root@server:# ping 10.25.255.254 PING 10.25.255.254 (10.25.255.254) 56(84) bytes of data. 64 bytes from 10.25.255.254: icmp_req=1 ttl=64 time=7.65 ms 64 bytes from 10.25.255.254: icmp_req=2 ttl=64 time=7.49 ms 64 bytes from 10.25.255.254: icmp_req=3 ttl=64 time=7.69 ms 64 bytes from 10.25.255.254: icmp_req=4 ttl=64 time=7.31 ms 64 bytes from 10.25.255.254: icmp_req=5 ttl=64 time=7.52 ms 64 bytes from 10.25.255.254: icmp_req=6 ttl=64 time=7.42 ms But I can't ping past the LAN interface: root@server:# ping 10.25.255.1 PING 10.25.255.1 (10.25.255.1) 56(84) bytes of data.

  • Network config / gear question

    - by mcgee1234
    I have been tasked with setting up a fairly straightforward rack in a data center (we do not even need a whole rack, but this is the smallest allotment available). In a nutshell, 4 to 6 servers need to be able to reach 2 (maybe 3) vendors. The servers needs to be reachable over the internet. A little more detail - the networks the servers need to reach are inside of the data center, and are "trusted". Connections to these networks will be achieved through intra data center cross connects. It is kind of like a manufacturing line where we receive data from one vendor (burst-able up to 200 Mbits), churn through it on the servers, and then send out data to another vendor (bursts up to 20 Mbits). This series of events is very latency sensitive, so much so that it is common practice not to use NAT or a firewall on these segments (or so I hear). To reach the servers over the internet, I plan to use a site to site VPN. (This part is only relevant as far as hardware selection goes). I have 2 configurations in mind: Cisco 2911 (2921) (with the additional wan ports module) and a layer 2 switch - in this scenario, I would use the router also for VPN. Cisco 3560 layer 3 switch to interconnect the networks inside of the data center and an ASA 5510 (which is total overkill, but the 5505 is not rack mountable) as a firewall for the Wan side (internet) and VPN. I envision the setup to be as follows: Internet - ASA - 3560 Vendors - 3560 - Servers The general idea is that the ASA acts as a firewall and VPN device and the 3560 does all the heavy lifting. The first is a fairly traditional setup but my concern is performance. The second is somewhat unorthodox in that the vendors are directly connected to the layer 3 switch without passing through a firewall. Based on my understanding however, a layer 3 switch will perform substantially better as it will do hardware (ASIC) vs. software switching. (Note that number 2 is a little over the budget, but not unworkable (double negative, ugh)) Since this is my first time dealing with a data center, I am not sure what the IP space is going to look like. I suspect I will retain a block(s) of public IPs, vlan them to individual interfaces for the vendor connections and the servers (which will not reachable from the wan side of course) and setup routing on the switch. So here are my questionss: Is there a substantial performance difference between 1 and 2, i.e. hardware based switching on a layer 3 vs a software base on the 2911? I have trolled the internet and found a lot of Cisco literature, but nothing that I could really use to get a good handle. The vendors we connect to are secure and trusted (famous last words) and as I understand it, it is common practice not to NAT or firewall these connections (because of the aforementioned latency sensitivity). But what what kind of latency are we really talking about if I push the data through a router (or even ASA for that matter)? For our purposes, 5 ms will not kill us, 20 or 30 can be very costly. Others measure in microseconds, but they are out of our league. Is there any issues with using public IPs on a layer 3 switch? I am certainly not married to either of these configs, and I am totally open to any ideas. My knowledge (and I use the term loosely) is largely from books so I welcome any advice / insight. Thanks in advance.

    When I did a dist-upgrade of my ubuntu 10.04 server, it automatically installed Decnet, and it trew up ncurses based configuration wizard. I have never heard of Decnet, but I followed the instructions in the wizard, and accepted for it to be installed, and it lead to the disconnection of 2 of my internet uplinks, and the hosted website stopped responding on WAN side. Then I purged Decnet, and rebooted the server, and everything went normal. So why did my server install Decnet when I did dist-upgrade?

  • Mirroring: what happens if principal loses contact with both mirror and wittness?

    - by TiborKaraszi
    Imagine a database mirroring setup where you have two LANs with a WAN link in between. Let's call them site A and site B. Say that principal is currently in site A, and both mirror and witness are in site B. I.e., we are running database mirroring with a witness, and assuming we are running safety FULL (synchronous), we have auto-fail over. Now, what is really fail over when it comes to mirroring? the simple answer is that the mirror will finish the recovery process (UNDO) and make the database available....(read more)
