Hi listmates,
Happy Thanksgiving!
Does anybody know if there is a convenient utility to configure
iptables on a CentOS 5.4 or 5.3 machine to do port forwarding? And if
not, where and how does one put the requisite commands?
Thanks.
Boris.

Well after running into more issues with the connections, we wound up
putting a third network card in the main server. They thought this a
better solution rather than forwarding the packets.
So now my issue is I have 3 nics.

eth1 - x.x.x.x/255.255.255.252 - Public
In the case of the OP, I would urge him to evaluate if that network
topology really makes sense. Does it make sense having two hosts with
two different connections? In that case, does it make sense to run

I think port forwarding is working fine, it's the routing of
the traffic back to the source that is not because linux doesn't
handle multiple default gateways very well out of the box. Look
