In a recent study of P2P real-time video, signaling and stun server is deployed on the public cloud (ali), measured results for the same local area network (LAN) finally, two mobile devices can link to communicate; 4 g and WiFi, movement 4 g, 4 g and unicom mobile 4 g 4 g and telecommunications, unicom, 4 g 4 g and telecommunications are all can pass;
Again after the test found that unicom 4 g and WiFi, telecom 4 g and WiFi, WiFi and WiFi can communicate occasionally, but most are not, test the NAT to telecom 4 g or unicom distribution of 4 g network outside the network IP mapping is a change, as telecom and unicom 4 g 4 g allocation is more IP, and mobile 4 g to assign the public IP has always been a () in the p2p connection to use, and telecom, unicom, 4 g to assign the public IP has been change, consult everybody a great god, and I have a small white, can you give advice on the allocation of telecom and China unicom in how public IP has been the change can change the stun configuration to a fixed distribution can be directly two client directly connect public IP, or only consider conical routers use stun penetrate, without considering the everybody under the great god give advice
