I’m fairly in the PBX arena so please bear with me.
I have installed FreePBX on a CentOS linux box. I am able to make calls between phones internally and need to take things to the next level. I recently purchased a trunk and a few DIDs from SIPStation. Everything appears to have installed correctly but I am thinking I am still not forwarding the ports correclty from my firewall to the PBX box.
I am using a Juniper SSG5 and have successfully forwarded ports for other functions like a web server and an OpenVPN server using a VIP. However, the ports suggested for SIPStation is causing me some frustration. The suggested ports are TCP and UDP on 5060 and UDP ports 10001-20000. I “thought” I have configured that correctly but something must be wrong as I continue to fail the firewall test with the following error message :
FIREWALL TEST WARNING
The test timed out which means your firewall is probably configured wrong.
If subsequent tests fail, check your port forwarding on the firewall.
In the Connectivity->SIPstation section, the primary and secondary server are registering successfully and I get green lights on both of those.
Also, I can call an outside phone number and it will ring but answering does not give any audio in either direction.
If someone who has got this running on a Juniper firewall could please share their config file sections I would be very appreciative. Reading some other posts makes me think it is an ALG issue. I tried adding IGNORE to the application in the policy but that didn’t work. I am not sure how to shut it off completely. Some posts I read said it has to be shut off and others said it has to be turned on, which is adding to my confusion. I am just using the WebUI right now but can console into the box if I have to.
Version Info :
Firewall Juniper: SSG5
Hardware Version: 710(0)
Firmware Version: 6.3.0r14.0 (Firewall+VPN)
PBX Firmware:10.13.66-16
PBX Service Pack:1.0.0.0
FreePBX 13.0.192.19
The SSG is the only device between the pbx and the outside world. There will be about 10 phones on the internal network when all is finished. I have about 6 of them set up so far. Aastra 6757i’s.
Thanks Tony. I was able to get into the box and turned off ALG with the “unset alg sip enable” command but unfortunately it is still not working.
Below is my full config file for your review. I have tweaked numerous things in trying to isolate and fix this issue so perhaps I screwed something else up.
The policy (#7 & 8) are currently sitting with application set to SIP but I have tried setting both to “NONE” as well as “IGNORE”, all with no effect.
Thanks for your help with this.

Anyone have a config file I can compare to mine? I really need to get this traffic flowing and I’m starting to get some heat so getting desperate here. Thanks!
