Solved Firewall test fails

[mickeyr61]

Hi, I installed the 3CX on premises. Running the firewall test, gives me two errors. I have searching the Internet for a solution, but until now no results. Don't know anymore what I should do. This is my firewall rule:



These are the errors:

• resolving 'stun-eu.3cx.com'... done
• resolving 'stun2.3cx.com'... done
• resolving 'stun3.3cx.com'... done
• resolving 'sip-alg-detector.3cx.com'... done
• 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 60057. (How to resolve?)
  • starting service... done

I am using Version 20.0 Update 3 (Build 806 Release), Modem is a Zyxel EX5601-T1. The image I am using is the standard image with no modifications running on Debian. I only run the admin console locally, so no port 80 en 443 opened.

The problem is solved! The problem was thFQDN was pointing to the old IP address. Changed it to the new IP address and everything works as designed.
