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...
