MLDonkey built from 3.2.1 release source, enabling (among others) the BT protocol. Running under Debian 12.

The setting "client_bind_addr" (used for P2P client connections) is set by myself as 10.46.46.5. Things work as expected, but for one thing.

Short excerpt from 'netstat -puant' for mlnet:

udp        0      0 10.46.46.5:14663        0.0.0.0:*                           75004/mlnet
udp        0      0 10.46.46.5:14664        0.0.0.0:*                           75004/mlnet
udp        0      0 0.0.0.0:14665           0.0.0.0:*                           75004/mlnet
udp        0      0 10.46.46.5:14666        0.0.0.0:*                           75004/mlnet

As can be seen, the various P2P services in use respect the setting and properly bind to 10.46.46.5 ... except for the BT DHT service (configured by myself to use UDP port 14665), which here incorrectly binds to 0.0.0.0.
