IP Port Forwarding

This package contains a tool to forward connections to hosts on your private network. Private networks are usually masqueraded and cannot be reached from the Internet. IP Port Forwarding makes it possible to make individual ports on the private networks reachable from the outside.

IP Port Forwarding does address rewriting for that purpose and is much faster and cleaner than any redirection program I have seen.

You need to have either a Kernel Version >=2.1.80 or apply the supplied patch
