I have tried every possible combination of rules, port forwards, etc to get my incoming SIP peering working.
No matter how I configure porting forwarding I always get denied:
2022-10-17T15:35:27-04:00 208.81.0.253(Peer):5060 FusionPBX:5080 udp Default deny / state violation rule
If I force a re-registration via fusionpbx it will work for a short time, after a random amount of time the above deny/state violation rule occurs.
With out having to use sipproxy could someone give me my an example of how it should be configured?
Are you port forwarding high ports (UDP 1024 - 65535) from your SIP trunk provider? I also have both UDP and TCP on 5060.
Bart...
I'll try that tomorrow as it seems to be working with nothing port forwarded. I just changed the Firewall Optimization to conservative and everything seems to be working. I am thinking that states between my system and my peer were being dropped prematurely.
