Hi, I'm trying to implement something with STUN (with PJSIP) as following flow: [IE] <--TCP/UDP trans.--> [agentC] <----STUN-----> [agentS] <--UDP/TCP trans.--> [Apache] And the [TCP/UDP trans.] part is ready. The agentC might have the stun mapped address 1.1.1.1:11111 while agentS might have the stun mapped address 2.2.2.2:22222 Now agentC send a [HTTP GET] to agentS: Question: 1. What will be the outgoing port of agentC? will it through NAT port 11111 or will be a random port[ex:37654]? 2.How should the agent reply the html tags? Reply to the 11111 or the previous port[ex:37654]? 3.If the agentC is behind a symmetric NAT (while agentS behind a full cone),could agentC connect to agentS and could agentS reply to agentC? Sincerely, Smith Lai
