So should I have to give the same treatment to method=="CANCEL" as method=="BYE"? i.e.: if (client_nat_test("3")) { setflag(7); force_rport(); fix_nated_contact(); };

Hi Alberto!
The BYE message from the client has no 'rport' paramter in its Via: header. Thus, ser sends the response to the IP:port in the via header. As there is no port, ser assumes port 5060.
You can manually add the rport paramter by using force_rport(). Then, ser will add the port from which it received the message (61133) and will use this prot for responses.
