Embodiment Construction
[0018] The 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 specified NAT port mapping), and a control program. see figure 1 , the concrete steps of the present invention are as follows:
[0019] Step 1: Map client A to NAT through node UPnP port B Initiate a port mapping request.
[0020] Step 2: If the port mapping request is successful, feedback that UPnP has successfully established port mapping on the NAT to the node. If the feedback data cannot be obtained, proceed to step 4, and connect to the STUN server C to obtain the port.
[0021] Step 3: Pass the established port mapping above to the STUN client to optimize the STUN client and establish connections such as heartbeat messages with the STUN server. The STUN client here is the key point. The optimized STUN client can accept the specified NAT port mapping, can quickly map valid ports, and get connected to ...
