[OpenSIPS-Users] Error relaying ACK to the same IP but different port

[Gustavo Mistrinelli]

You're right Adrian, I've pasted my confing here<http://pastebin.com/m7ce61f09>(
http://pastebin.com/m7ce61f09)
It's large, and it has not "friendly" comments, but may be you can see if
there are logics error.
Be free to ask if you need more explanation about this issue.

Thank you

Gustavo
