[CentOS] Routing problem

Jeff,

I think we are on to something here.  I added a static route on the
192.168.1.1 router to the 192.168.1.224 with the gateway address equal to
the eth1 IP address on the firewall.  I can now ping 192.168.1.1 from behind
the firewall but I still can't ping 209.73.186.238 (yahoo) from behind the
firewall.  I can ping yahoo from the firewall.

Any other thoughts?

Thanks,
---Marc

What's the default route on the 192.168.1.5 and .3 machines?  The router
  or the firewall?

It looks like your router doesn't know how to get back to the
192.168.202.x network.  If you add a static route on your router that
tells it to send traffic destined for the 192.168.202.x network to the
192.168.1.224 interface on the firewall box I think it will start
working for you.
