[0018] The present invention consists of a UPnP port mapping client running on a network device node, a customized STUN client running on a network device node (which can accept designated NAT port mapping), and a control program. See figure 1 The specific steps of the present invention are as follows:
[0019] Step 1: Map client A through the node's UPnP port to NAT B Initiate a port mapping request.
[0020] Step 2: If the port mapping request is successful, feedback that UPnP successfully established port mapping on the NAT to the node. If the feedback data cannot be obtained, proceed to step 4 to connect to the STUN server C to obtain the port.
[0021] Step 3: Pass the port mapping established above to the STUN client to optimize the STUN client and establish a connection with the STUN server such as heartbeat messages. The STUN client here is the focus. The optimized STUN client can accept the specified NAT port mapping, can quickly map an effective port, and get a connectio...
