I have a question:  Why do you want to do this?  Do you have multiple
routes to remotes sites so that you have a need for a routing protocol
internally?  You say "a" Checkpoint firewall.  If you have just one,
I don't see how you need rip.  Your firewall will be the default route
for your internal clients.  Set the default route on your firewall to
point at your external gateway router.  That is where you want your
rip.

It typically is not considered "best practice" to run a routing protocol
on your fw, although I am not familiar with any known exploits.
