static route
man route
say for example, eth1 is 192.168.1.204 and you have a router that has an
ip address of 192.168.1.1 and your internal lan has an ip network
address scheme of 192.168.0.0/24
Then (assuming your router will permit this - you might want to be
'restrictive' on exactly which ports are forwarded through the router
from your Linux box to the internal LAN as your Linux box is in
untrusted waters)...
route add -net 192.168.0.0 netmask 255.255.255.0 dev eth1
(I think - this of course is untested).
plink around with this manually and once you get it to work...you could
add this command to /etc/rc.d/rc.local like...
route add -net 192.168.0.0 netmask 255.255.255.0 dev eth1 &
so it is created every restart
