This makes the plugin work better when testing client side connections. traffic on this port. What seems very interesting is that for a time STUN traffic seems to be duplicated to multiple IP address destinations: The duplicate traffic flows exist for the start of the call, but then traffic settles on what appears to be a direct path to the 23.100.65.165 IP address, accounting for 8,303 packets: The final flow above looks like a similar connection you would expect to see when an external Skype4B client is connecting to the 50K port range of a call negotiated through the external interface of an edge server. You can also set a filter to capture only the packets that . better when testing client side connections. The settings are accessed through. The plugin by default will listen on port TCP 443 and UDP 3478 for traffic, this will capture traffic that is sent to Edge (and other) servers. Therefore, Wireshark uses heuristics to try to identify the protocol as best as it can, but heuristics can guess incorrectly. In the packet detail, opens all tree items. Work fast with our official CLI. i wonder if someone would push Microsoft into making the protocol public. Port 443 is the standard port used by Internal Edge services.
