First, I will describe the way the network is setup. (xxx represents what i left out for security sake) My upstream provider provides access through a ethernet connection. To this particular ethernet connection, it has a IP address of 207.xxx.xxx.27. And to this IP, all of my subnets are forwarded to. The setup for that ethernet card looks like : ed1: flags=8843 mtu 1500 inet 207.228.xxx.27 netmask 0xffffff00 broadcast 207.228.123.255 ether xxxxxxxxxxxxxxxxxx There is a second ethernet card in the computer as well. This is where I list the machines local IPs on the subnets that are forwarded to the above IP. Also, the other machines on the network are connected to this interface via some hubs. The setup of that ethernet card looks like : vr0: flags=8843 mtu 1500 inet 207.148.xxx.50 netmask 0xfffffff8 broadcast 207.148.xxx.55 inet 207.148.xxx.51 netmask 0xfffffff8 broadcast 207.148.xxx.55 inet 207.148.xxx.52 netmask 0xfffffff8 broadcast 207.148.xxx.55 inet 192.168.0.4 netmask 0xffffff00 broadcast 192.168.0.255 ether 00:80:c8:e1:47:b2 media: 100baseTX supported media: autoselect 100baseTX 100baseTX 100baseTX 10baseT/UTP 10baseT/UTP 10baseT/UTP And the machines on the network have IPs 207.148.xxx.5x and so on... Everything seems great so far. From the outside world, people are able to access the web servers running on .50, .51, .52 and I am able to access them anywhere on the network as well. However, on the machine that has those 3 IPs, it is only able to access .50 itself! .51 returns HOST IS DOWN and .52 doesnt do anything when trying to ping or access them via http. Like I said earlier, any other machine in the world is able to ping and access these IP EXCEPT for the machine that has them! I think it may be something to do with my routing. Here is what my table looks like right now.

I have been trying to figure it out for the last week and haven't got anywhere with it yet. Thanks.
