Public bug reported: https://datatracker.ietf.org/doc/html/rfc6886#section-3.4:
"When a mapping is destroyed successfully as a result of the client explicitly requesting the deletion, the NAT gateway MUST send a response packet that is formatted as defined in Section 3.3, "Requesting a Mapping". The response MUST contain a result code of 0, the internal port as indicated in the deletion request, an external port of 0, and a lifetime of 0." According the specs, the external port in the removal response should be zero. However, the code at https://sourceforge.net/p/dcplusplus/code/ci/default/tree/dcpp/Mapper_NATPMP.cpp#l130 makes the removal fail if the mapped public port in the response doesn't match the originally mapped one, causing an error message on every removal. ** Affects: dcplusplus Importance: Undecided Status: New -- You received this bug notification because you are a member of Dcplusplus-team, which is subscribed to DC++. https://bugs.launchpad.net/bugs/2078913 Title: Failed to remove port mappings with the NAT-PMP interface Status in DC++: New Bug description: https://datatracker.ietf.org/doc/html/rfc6886#section-3.4: "When a mapping is destroyed successfully as a result of the client explicitly requesting the deletion, the NAT gateway MUST send a response packet that is formatted as defined in Section 3.3, "Requesting a Mapping".
