my scenario like this:
PHONE1->FS (192.168.0.4) -> NAT1 (Public IP 1.2.3.4) -> INTERNET -> NAT2 (Public IP 5.6.7.8) -> PHONE2 (192.168.1.100)
First, I have forwarded sip port and rtp port.
I have try servaral configurations in http://wiki.freeswitch.org/wiki/General_NAT_example_scenarios and without luck!


PHONE2 only regists to FS, how can FS gets through NAT2 to PHONE2, include sip signaling and rtp connection ?
