Asterisk behind pfsense (no sound)
-
Has anyone ever asked WHY its so difficult to make SIP work behind a pfSense NAT, compared to other routers?
I have no problems with it.
When using many sip devices behind any firewall, consider using sipproxy.
RTP issue sample:
You redirected ports from 17000 to 18000 to your sip server.
Your second sip device received a call and remote server sent rtp to 17454. In this case you will have no audio and pfSense is not guilty.SIP issue sample:
You redirected port 5060 to your sip server.
Your second sip device registers at voip.com. When voip.com checks registration who will receive this info? Again pfSense is not guilty.Try to set different sip ports/rtp range to each sip server/device behind your firewall.
:) Just remember that computers do what we tell them to do, not what we want to do. :)

I am going to make one more test over sip tonight and see how far I can get again. In my case its was only one device and I was still unable to get outgoing RTP to function properly.
My sip devices talk to asterisk and than asterisk talks to my provider.I will reply back and see what are the results again.

I am sorry but in pfsense sip is plain impossible. I just tried everything I can think of and nothing works!
If you have your sip working behind your pfsense by all means please post your pfsense config and prove me wrong. but for now I stand by this. SIP is not possible behind pfsense. -
Do you need inbound calls?
If don't you do not need any nat rule, just outbound.

Somebody under general gave me some hints that made the registration possible. the issue has been that outbound is not possible.
And I do need inbound and outbound. -

can you bridge your router to have real ip at wan?
my setup is very simple:
provider–>real ip-->pfsense->--192.168.3.x ip->asterisk server.
nothing different from nat inbound ports and sip_nat.conf.

Well I am back…. Here is what I can say... For an unknown reason I am not able to get SIP working over port 5060. As soon as I switch to 5080 everything started to work as it should. and no I have no other sip device except for my asterisk pbx.
odd..... -
Great news!!! :)
Some dsl routers has a 'sip Alg' option that break out sip comunication. I have no idea why.
Maybe you have something like that on you network. -
