Working configuration for 3CX PBX - Static port mapping

Athena4537

Hello,

Does anyone ever tryed to configure an UTM for 3CX PBX ?

I'm unable to pass the Firewall Check, probably because of the NAT rules.

In other word : how can I ensure that all SIP communication (port 5060 TCP/UDP for example) will keep port 5060 on both source and destination ?

Thanks in advance for your help.

    What hints do you get from #1 in Rulz?

    Hi BAlfson,

    From rule #1, I obtained (from FW log) : outgoing packet OK.  But nothing else...

    From the 3CX logs, I could see the answser arrived, but with a port translation (port 5060 has been translated to xxxxx).

    How can I avoid this translation (knowing that both source and destination UP are known, and port must stay 5060 from start to end) ?

    Bernard, please show one or two relevant lines from the Firewall and 3CX logs.  Alone among the logs, the Firewall Live Log presents abbreviated information in a format easier to read quickly.  Usually, you can't troubleshoot without looking at the corresponding line from the full Firewall log file.

    Cheers - Bob

    THANK YOU for the rulz link.  I just spent 8 hours trying to figure out my one way audio issues.  Application control streaming block kicked my ass all day.  Never would have looked at that without seeing this post.

    FREE BEER FOR YOU!
