Firewall Tester Errors

[SonnyH]

Hello,
I just ran the Firewall Tester and received the following 2 errors:
testing 3CX PhoneSystem 01 SIP Server... failed (How to resolve?)

• stopping service... done
• detecting SIP ALG... not detected
• testing port 5060... Mapping does not match 5060. Mapping is 1073. (How to resolve?)

I have looked at "How to resolve" and am not sure what to do.

3CX is running on a local Pi-Standard Annual, with 18.0 (Build 314). The system has been running fine for a year now.
The only change is my Standard Annual recently renewed.
I have no apparent issues with the system.

Thoughts/suggestions?

If there's no problems, you can do nothing.

Depending on how your firewall handles traffic you might indeed not notice any issues, but, what you might want to look for to rectify this is firewall features on the such as port remapping or features that can prevent port preservation and have them disabled.
