I have srcnat action=same , also have tried masquerade, with and without SIP helper app, 3.10-3.11
I have an OpenSER box that a Polycom(multiple actually) registers to. This works fine. The OpenSER talks to an Asterisk box on another (Also public) IP. I am getting some strange one way audio issues.
I am seeing alot of unreplied UDP connections - basically for some reason the tik is not allowing the UDP in from the Asterisk box in…
Hopefully this will make sense…
192.168.254.254 is the phone behind the tik
x.x.x.x is the public IP of the Asterisk server
: public IP of the Mikrotik
unreplied entry in connection track appears
udp 192.168.254.254:2226 x.x.x.x:18330 19s
WAN port torch shows
source address x.x.x.x:18330 udp going to :1138
and also
source address x.x.x.x:18330 udp going to :2226 (which is not being NATed to the phone since it’s showing up unreplied)
the RTP audio should be going to :2226 and being passed to 192.168.254.254:2226
but it’s not allowing it through - as the unreplied in connection track shows
why is this?
here’s when I log it, it’s just coming into the tika nd getting lost
23:34:24 firewall,info input: in:ether1 out:(none), src-mac 00:60:e0:44:2b:e4, proto UDP, x.x.x.x:18330->:2226, len 180

this repeats as long as the call is up
