A first device in a first local area network (LAN) searches for a first Universal Plug and Play (UPnP) enabled router with a first public network address. If found, the first device obtains the first public network address of the first router and configures a first mapping table of the first router to associate several ports number to the first device. These actions may be repeated by a second device in a second LAN for a second UPnP enabled router with a second public network address and several ports number. The two devices then connect through a secondary communication channel (e.g., a telephone network) to exchange networking information. The two devices then use the networking information to establish a computer network connection over a public computer network that couples the first and the second LANs for point-to-point communication.
