Hi people,
i have problem with IAX2 between two asterisk PBX. When i try call some
number i get "INVAL" packet, but when i try call same number via
OpenVPN
(is between this two asterisk) call is working fine.So i debug
communications and here is my opinion ...
Schema of connection:
Asterisk1 -> ADSL router with NAT -> INTERNET -> Asterisk2
A)Calling directly via public IP's (port 4569 is forwarded on ADSL modem
to asterisk1) - not working

Only difference what i see is that in first case is the source port of
"far-end" changed from "4569" to "9785" because of
NAT of ADSL modem.In
case of calling thru openvpn is port unchanged ... It is possible thats
the problem?
Can somebody help me with my problem? Thanks a lot....
