Yes, thanks, obviously my config is not for every NAT case XD

Anyway I'll try to add in a future a solution for that. I could test to if the 
caller Contact and called Contact are "similar" private IP. Anyway this is 
not 100% secure since we cannot know which netmask are they using, so we 
cannot know if they are in fact in same LAN.
Any suggestion?
