Hi all, The question is about the pjsua application, used with STUN (using host stun.pjsip.org) The public IP address reported is correct, however the mapped ports look the same as their original source ports. i.e. 5060 (SIP UDP port), and 4000-4007 (RTP/RTCP ports) It seemed to be valid to me initially since some home routers may perform address translation alone. But I checked if these ports are open from online port scanners, and they seem to be closed from the outside. I've tried the application behind two different routers configured with NAT. The behavior seems to be same. I didn't get a different port mapped to the source ports. The NAT types detected were "port restricted" and "restricted" when using different routers. I've only used the --stun-srv option without TURN/ICE. Is there any configuration I need to do to get the mapped ports apart from specifying stun-srv?
