Thanks. Based on the mapped address from test 1 and test 1B: Test 1: 88.88.88.88:35077 Test 1B: 88.88.88.88:1024 So that's symmetric. And the result is the same with Vovida client result (Independent Mapping). The Jstun result (Port restricted Cone) then becomes questionable. On a side note, the behavior of your NAT is also questionable (is it still Linux masquerade?) as it doesn't seem to do symmetric mapping for SIP traffic. This kinds of affirm our suspicion that Linux NAT (this indeed you're using Linux NAT) has some kind of SIP ALG inside.
