If you need more than one default gateway you likely will need to use iproute2 to set that up. If you have 1 default gateway and want to have another route(s) pointing to another gateway add them to /etc/sysconfig/static-routes e.g. any net 192.168.0.0 netmask 255.255.0.0 gw 10.254.113.1 not sure why the syntax is not the same as the route command, it's similar but not exactly the same. nate
