Firewall Requirements

This Article Applies to:

  • AVG Business Cloud Console


For overall functionality, and to enable the Antivirus client and/or the management console to authenticate/update, you must allow certain ports and URL addresses through your firewall or proxy server.


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.


  • TCP 80 – Internet vulnerability checks and feature updates
  • TCP/UDP 443 – Encrypted communication
  • TCP 4158 – Mirror, for local updates within local network
  • TCP 7074 – Remote Deployment within local network
  • TCP 7500 - For push notification services
