Hey,
What you need to do is write a script and run the script
in rc.local for startup
Let me give you some example, i think this will help you.
A proper configuration will look like below :
2 Network cards.
[192.168.1.1-eth0]<=connect to hub or crosslink to other pc=>PC
[ ]
[ ]
[ ]
[xx.xx.xx.xx-eth1]<=crosslink to DSL Modem=>[0000]
save this script in a file,
then run in rc.local
this command run where the remote pc and server are in same
subnet mask
if different subnet mask, you need to masquerade two different network
==================================================================
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -P POSTROUTING DROP
iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -d 0.0.0.0/0 MASQUERADE
===================================================================
