Firewall Requirements

This Article Applies to:

  • AVG Business Antivirus

For overall functionality, and to enable the Antivirus clients to authenticate/update, you must allow certain ports and URL addresses through your Firewall or Proxy Server.

Geoblocking

AVG web services are hosted in many countries around the world. Therefore, we do not recommend geoblocking in your firewall settings.

If geoblocking is necessary, we recommend you set URL Allow rules to supercede geoblocking, so AVG traffic can still be allowed.

Ports (TCP & UDP)

  • 80 – Internet Vulnerability Checks and Feature Updates

URLs

  • *.avast.com
  • *.avg.com
  • *.avcdn.net
