It's been a while but last time I checked you couldn't do forwarding to a system unless that system was behind the system that was doing the forwarding using normal iptables. What I do is use a specialized utility, there are two such utilities that I know of that handle tcp forwarding in this manor: rinetd and redir. The only downside is the destination system will not see any of the original IP addresses connecting, it will only see IPs of the system doing the forwarding. I don't think either rinetd or redir are available in the default CentOS installation you probably have to find them elsewhere on the net. As for non-TCP stuff, I don't know off the top of my head. nate
