Actually a garden-variety router _will_ solve thise problem, even if you
have both machines with externally-reachable IP addresses. Just disable
the NAT on it ( my Netgear RP114 can do that easily ).

I do it without RIP. All you need to do is enter the static routes into
the router. In fact I do this even when the ISP provides RIP, because
a) the routing isn't that complex, I have exactly 1 internal network and
everything else is on the WAN ( translation: 1 normal route for the
internal subnet, 1 default route ) and b) RIP provides no strong security
or protection against forged updates, so accepting RIP allows someone
else on Cox's network to update your routing tables to run your LAN's
traffic through their machine.
