VPN upgrade - NO internet access

I had this problem as well. Disbling Enhaced Firewall helped and internet was accessible via VPN. So does one always have to disable Enhanced Firewall when intention is to use VPN? Is not that little crazy from customer point of view? Is not there any way how Enhanced Firewall could be adjusted so it does not block another product of the same company? Or is Enhanced Firewall product of Avast and it blocks AVG Secure VPN, because it is product of AVG :-)))? 
Thx, M

Please disable the Enhanced Firewall of your AVG Internet Security and turn on the AVG Secure VPN and then check if the issue persists.

Since the last upgrade I cannot access the internet when the VPN is active. I can if I disable it.
