Patrick,
I'll assume you have Red hat Linux or similar based distro. The file you want to edit to add a permanent route is /etc/sysconfig/static-routes. Also to add / remove a route on the fly for a host

route add -host 10.10.10.45 gw 192.168.0.1
route del -host 10.10.10.45 gw 192.168.0.1

To Add / Remove a network

route add -net 10.10.10.0/24 gw 192.168.0.1
route del -net 10.10.10.0/24 gw 192.168.0.1

To add / remove a default gateway

route add default gw 192.168.0.1
route del default gw 192.168.0.1

Also as always netstat -rn to check current routing table. I hope I covered all the bases for you if this helps please don't forget the points.

Hi,
you can add the following two lines to the file "/etc/sysconfig/static-routes":
eth0 net 192.168.2.0 netmask 255.255.255.0 gw 192.168.2.1
eth1 net 192.168.1.0 netmask 255.255.255.0 gw 192.168.1.2
In this Example
network number - 192.168.2.0
network mask - 255.255.255.0
gateway - 192.168.2.1
