I can detect NAT during clients REGISTER, but not the type of nat (the mapping reutilization method it uses). That's why I tried to do that: to send a request from an transport address and receive it from another, so I can check the source transport address to figure out if NAT is re-using the same mapping.

Thanks, Iñaki.

That is not possible at all, a UAS decides where to send the reply based on
the "received" and "rport" values (if UAC indicated it) that the UAS
transport layer has set when receiving the request.
