Hi Mauro,

The following is taken from:
http://www.redhat.com/support/resources/howto/sysconfig.html

--
/etc/sysconfig/static-routes
Contains lines of the form:
device net network netmask netmask gw gateway

device is the device name for which to have the route brought up.

You can also put the "route add/delete" statements in a script and place them in the /etc/rc2.d directory.

Make sure you start the script name with a capital "S" --> S999RouteAdd.

Also don't forget to chmod +x it.
