Java IP Routing
I am using RedHat Linux 9, In this box their are two lan intefaces.

eth0 ====> LAN
192.168.100.100
255.255.255.0

eth1 ====> Internet
Static IP
255.255.255.0
59.144.168.226 (Gateway)

I want to define a gateway 59.144.168.226 for my LAN machines 192.168.100.0/255.255.255.0

so

First I enable IP forward
echo "1" /proc/sys/net/ipv4/ip_forward

Second
route ..................... ???

Please Help Me

You probably mean "echo 1 > /proc/sys/net/ipv4/ip_forward"
Your internal lan cant have a public address as a gateway i think , if the lan needs to talk to the outside, one way is to use masquerading at 192.168.100.100 so the gateway needs to be 192.168.100.100 i guess ...
But what are you trying to do ?

Correction:

You can certainly have the LAN subnet 192.168.100.0 have 59.144.168.226 as a default gateway.

The command would be something like this:

Code:
/sbin/route add -net 192.168.100.0 netmask 255.255.255.0 gw 59.144.168.226 metric 1
