How can you play "Pocket Tanks" online?

In order to play Pocket Tanks with another PC, both PCs must be on the same Local Area Network (LAN). To play a PC not on your LAN, both computers must use a Virtual Private Network (VPN) service to connect as though they were on the same LAN.

When creating a VPN connection, any PC that connects to the VPN is treated as though it were locally connected. With such a connection, Pocket Tanks is able to detect other players in the VPN no matter their physical location. According to the official Pocket Tanks forum, Hamachi is a popular service for quick and convenient access to VPN servers. The Evolve client also supports Pocket Tanks connections.
