Hello,
Thank you for posting in Q&A forum.
General speaking there's need to creat an inbound rule on the Windows firewall based on specific need.
1.Go to Control Panel -> System and Security -> Windows Defender Firewall -> Create a new inbound rule.
2.You can consult AVG support team and confirm which protocol and ports should be allowed on the server.
3.Once it's determined please select the profile and name the rule to get it finished.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best regards,
Jill Zhou
