Not an optimal setup. It would be far easier if you had separate networks,
and only a single box with connectivity to both. However, given the setup
you've described, the only real solution is to install some kind of
firewalling (ipchains, iptables, ipf, pf, etc.) on each multi-homed box.
Then configure each one to only allow the traffic you require between
the two networks, and block everything else.

PS. Use ssh, not rlogin.
