From looking at the code, the logic appears to be "is the traffic to or from UDP port 6635?" So *is* the traffic to or from UDP port 6635?
indeed udp.dstport is 6635 (IANA assigned for mpls-udp), so it turned out a host was using udp/6635 as ephemeral port to connect to a STUN server https://github.com/wireshark/wireshark/blob/075785bd20cad395141481a8a9639022bb963aee/services#L4843 https://github.com/wireshark/wireshark/blob/1539e455d70c5f340ce80021c770b8f992051ec2/epan/dissectors/packet-mpls.h#L67 Thanks a lot. ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-users Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
