STUNT
http://nutss.gforge.cis.cornell.edu/stunt.php
Simple Traversal of UDP Through NATs and TCP too (STUNT), which extends STUN to
include TCP functionality, is a lightweight protocol that allows applications
running behind a NAT to determine external IP and port-binding properties,
packet filtering rules and various timeouts associated with TCP connections
through the NAT.  Knowing these parameters allows applications to establish TCP
sessions between two NAT'ed hosts.  As a result P2P and other applications can
work through existing NAT infrastructure without sacrificing the benefits of
TCP.
