[OpenSER-Users] OpenSER looping routes back to itself.

Running OpenSER v1.1.1 with internal ip for sip client connections and ext ip to connect to sip providers. I am getting loops in my calls sometimes... They stop after reaching the max hops trying to send the BYE message to it self. I am wondering if it is the record- route that I see that includes the internal IP. The 483 error is U 2007/07/30 00:49:56.133157 192.168.18.22:5060 -> 192.168.18.22:5060 SIP/2.0 483 Too Many Hops. From: <sip:15126461516@192.168.18.1:5060>;tag=nu-481d-6c62.
