[OpenSIPS-Devel] [opensips] NAT Via Test Failure (#401)

[jalung]

There is a client that cannot register because it is not detected as being behind a NAT. It will register if treated as behind NAT by force. The top most Via has a 10.x.x.x IP address, but neither nat_traversal nor nathelper can detect it (xxx.xxx.xxx.xxx is a public IP). Client tried to connect with and without STUN setting, but result is the same.
