How to configure AVG Firewall to allow VPN connection?

Various VPN applications use different protocols for their communication.
Therefore, if you find some blocked traffic in the Filter Device log, with protocol: 47 mentioned, please allow the GRE rule.
If protocol: 50 is mentioned there, please allow the ESP rule.
The GRE and ESP rules are already created within the AVG Firewall. You only need to change them to allowed, as follows:
AVG Control Center->AVG Firewall->Configuration->System tab

If you cannot find these two rules within the AVG Firewall, please run the Automatic Configuration Wizard again. It will automatically create them.
