Rechner 1:

ifconfig lo 127.0.0.1 up
route add 127.0.0.1 lo
route add -net 127.0.0.0 netmask 255.0.0.0 lo
route add 192.168.17.42 gw 127.0.0.1 lo
ifconfig eth0 192.168.17.42 netmask 255.255.255.0 up
route add -net 192.168.17.42 netmask 255.255.255.0 eth0

Rechner 2:

ifconfig lo 127.0.0.1 up
route add 127.0.0.1 lo
route add -net 127.0.0.0 netmask 255.0.0.0 lo
route add 192.168.17.43 gw 127.0.0.1 lo
ifconfig eth0 192.168.17.43 netmask 255.255.255.0 up
route add -net 192.168.17.43 netmask 255.255.255.0 eth0
