1. man arp (see the options -D and -s)

This would work like this (on the Cisco):
# conf t
(config)# ip route <IP of server1> <IP of Linux-GW>
(config)# ip route <IP of server2> <IP of Linux-GW>
(config)# end
# copy run start


PS: I dislike either of these setups. If you've got separate subnets, you
should have separate subnet addresses, IMHO. But the above should work
