However, if the IPs you give are accurate I'm not sure you've been assigned a subnet. Let's assume that you have, and the subnet in question is 38.185.233.160/27 (unlikely, since that's a 32 address subnet; however it's the only one I could think of that contains your addresses). In that case you'd set up your router like this: eth0 -> whatever the external IP is eth1 -> 38.185.233.175 routing table on router: default route gw [next hop for eth0] box1 and box2 would list 38.185.233.175 as their default gw. The next hop at the ISP also needs a route for network 38.185.233.160/27 pointing to the IP for eth0. I suspect that the above is all smoke and you've actually been assigned three IP addresses. You naturally want to place two of them behind a linux firewall. To do this you're going to have to configure bridging. In this scenario eth0 has IP address 38.185.233.175, but it also performs proxy ARP for 38.185.233.176 and 38.185.233.177. router then forwards all packets out eth1 so box 1 and box2 can communicate with the world. I have never set up bridging in linux; I'm ashamed to admit I'm all to familiar with bridging using "real" routers like Bay or Cisco gear ... I don't want to say more until I have a clearer idea of what you are trying to do and what your situation is. -- Nathan Norman "Eschew Obfuscation" Network Engineer GPG Key ID 1024D/51F98BB7 http://home.midco.net/~nnorman/ Key fingerprint = C5F4 A147 416C E0BF AB73 8BEF F0C8 255C 51F9 8BB7
