QUESTION 3CX 15.5/Nuc

[lrosenman]

I've just installed 3CX 15.5 system on my Nuc. The firewall checker doesn't seem to like my port forward.

I've forwarded
SIP/3CX * 5060,5090,9000-9079 192.168.200.26:5060,5090,9000-9079

the firewall checker says:

• resolving 'stun-us.3cx.com'... done
• resolving 'stun2.3cx.com'... done
• resolving 'stun3.3cx.com'... done
• resolving 'sip-alg-detector.3cx.com'... done
• testing 3CX SIP Server... failed (How to resolve?)
  • stopping service... done
  • detecting SIP ALG... not detected
  • testing port 5060... Mapping does not match 5060. Mapping is 1077. (How to resolve?)
  • starting service... done
• testing 3CX Tunneling Proxy... done
  • stopping service... done
  • testing port 5090... done
  • starting service... done
• testing 3CX Media Server... failed (How to resolve?)
  • stopping service... done
  • testing ports [9000..9398]... failed (How to resolve?)
    • testing port 9000... done
    • testing port 9002... done
    • testing port 9004... done
    • testing port 9006... done
    • testing port 9008... done
    • testing port 9010... done
    • testing port 9012... done
    • testing port 9014... done
    • testing port 9016... done
    • testing port 9018... done
    • testing port 9020... done

I can't use ALL those ports, and for my house only need 2-4 sessions, if that.

How can I change what port(s) it's using? How can I fix the mapping?

Also, how does the "free" license work after a year?

Thanks!
