- h43k3r 12y agoThis reminds me of a tool named pwnat by Samy, the myspace hacker. It is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with no port forwarding no DMZ setup, and no 3rd party involvement. The server does not need to know anything about the clients trying to connect.
