HI all, I've read the solutions proposed at http://www.openser.org/dokuwiki/doku.php/examples:caller-callee-behind-same-... 2 client behind the same NAT. The clients may be behind the same NAT, but on different sub-net (for example, one on 192.168.10.x and another on 192.168.2.x). In this case, checking source and destination IP, to discriminate against behind or not the same NAT, is not enough - they can't reach each othere anyway.
What do you think?
Regards, daniel
