Really simple application, but very powerful port forwarding app. This is not a replacement for iptables PREROUTING commands. This is for non-kernel port forward, redirecting, and more. It even supports transparent proxy forwarding. The only drawback is that this cannot be run from xinetd, it's meant to be a standalone daemon that handles a large scope of configurations.
