I had this problem recently and it turned out to be that ipv4 forwarding was turned off on RH9.
turned it on again and away it went.
you can cat /proc/sys/net/ipv4/ip_forward and see whether it's a 1 or 0. mine was 0 but i had a hell of a time getting it to turn on again.
even after editing /etc/sysconfig/network and setting forward_ipv4=yes it still was 0. don't you love it!
I installed webmin and set it to forward in there and that fixed it.
