Hint:
/etc/gateways
net 0.0.0.0 gateway <router-ip-here> metric 1 passive

and also take out the /etc/rc2.d/S99route.

On the Cisco router, turn (on or off, forget) unicast broadcast
 packets.

The unicast packet problem will do things like make your
server disappear from the network, but pinging some one
on your local segment should bring it back.

Turn the arp cache timeout to about 4 hours. (But
you may have to flush it by hand every so often when
you change machines on the network).
