Assuming you in reality have more than 1 IP address being routed to you, it's easy. You can't have the ppp0 and eth0 interfaces on icemark use the same IP. However, if you isp is willing to route you a /30, you'll be cool. Here's how you should be set up (assuming your ISP is sending you 193.135.252.177/30 aka 193.135.252.177 - .180, and the IP addr of your ppp0 is 193.135.252.47): icemark: ifconfig eth0 193.135.252.178 broadcast 193.135.252.180 netmask 255.255.255.252 route add -net 193.135.252.0 netmask 255.255.255.252 now bring up your ppp0 and set it to be the default route. Make sure your kernel on icemark has IP forward turned ON. firefranc: ifconfig eth0 193.135.252.179 broadcast 193.135.252.180 netmask 255.255.255.252 route add -net 193.135.252.0 netmask 255.255.255.252 route add default gw 193.135.252.178 If this is not the case, use a /24 from 192.168.0.0/16 for the ethernet interfaces on the boxes and use IP_Masquerade...
