Original Pull Request: https://github.com/netbirdio/netbird/pull/6177

State: closed
Merged: Yes

Describe your changes

Recognize NetBird's DNS forwarder port (22054) alongside 53 and 5353 in the packet capture text format, so UDP packets to/from the forwarder are parsed and summarized as DNS rather than shown as opaque UDP.

Use the nbdns constants (DefaultDNSPort, ForwarderClientPort, ForwarderServerPort) instead of magic numbers
