You need to make sure the other boxes send their packets to the router; that probably means they should have a static route for default to the router box (or if they're using Microsofts TCP/IP, just configure the router's address as a gateway). Use the eth0 IP for that. > Here's the output of "route": > > Kernel IP routing table > Destination Gateway Genmask Flags Metric Ref Use Iface > cs10.mil.ptd.ne * 255.255.255.255 UH 0 0 2 ppp0 > cs10.mil.ptd.ne * 255.255.255.255 UH 1 0 0 sl0 > 204.186.230.0 * 255.255.255.0 U 0 0 35 eth0 > 127.0.0.0 * 255.0.0.0 U 0 0 18 lo > default * 0.0.0.0 U 0 0 87 ppp0 > default * 0.0.0.0 U 1 0 15 sl0 You're using diald, right? This looks fairly good. However, I'm not sure about the metrics; you might want to convince diald to make the modem/ default route more "expensive" - say, still have eth0 at 0, have ppp0 (when it's up) at 10, and sl0 (where diald is listening) at 100, or something, so your box can't possibly get confused and send packets for the ethernet out via the modem. This should be easy to find in the docs. (And I'm probably just being paranoid here.) One more thing. > yet completely routed, but will be routed through the modem) are: > 204.186.230.1, 204.186.230.2, 204.186.230.3 . The first address is given You may want to check how much subnet bits you actually got, that is, if someone else may be using other 204.186.230.* addresses. In that case, you'd have to adjust the 255.255.255.0 entries in your routing table to have more 1 bits - this should also be an entry in diald.options. If your ISP did it right, you should have at least the lower three bits for your net - or maybe you really have the lower eight bits, just as configured. > _Any_ advice would certainly be helpful! Well, ignore any advice about proxy arp. You don't need it for anything. (Proxy arp convinces an ethernet that a machine is on that net, when it really only has some sort of connection to the machine doing the proxy arp. Its main use is for dialin servers which give out dynamic IP addresses to their clients, to simulate those clients being on the ISP net.)
