3CX V16 SP1 Still Fails Firewall Check?

[Frank86]

Hi,
Just updated from V15.5 SP6 no V16 SP1 on Windows, ran the firewall check and it still fails, just like the first instance I had updated over two months ago.

In both cases, everything works, no problem with calls. Is it still an open issue?

So SP1 has this in the change log:

[LIST] [*]Fixed Firewall Checker erroneously reusing same STUN transaction IDs, reporting false negative results for correctly open and NATted ports.
[/LIST]
So I believe it to be resolved. I just ran the checker on a v16 SP1 instance as well as a v16 SP2 Beta instance and they both came back clean. I don't recall if these ever had an issue previously.

Port 5060 passes once I put ANY under firewall -> Port forwarding -> TCP/UDP 5060 -> remote IPs (instead of just the IPs of my SIP trunk providers); that was my fault.

SIP ALG still fails, though. Always worked under 3CX v15.x

Well like you said, everything works. Firewall checker is just a tool to help troubleshoot issues. You have no issues so I wouldn't worry about it too much.
