The author of the infamous Samy Worm (who spent three years on probation, 90 days of community service and was also ordered to pay restitution for damages) has released a new tool that enables computers on separate LANs to establish a straightforward client-server type connection without any port forwarding or other special setup. According to Softpedia, the tool, called pwnat, employs some very creative use, or better said misuse, of features implemented by default in most routers.

"Pwnat, pronounced 'poe-nat', is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with no port forwarding and no DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect. There is no middle man, no proxy, no 3rd party, no UPnP/STUN/ICE required, no spoofing, and no DNS tricks."
