VPN exclude my external server drive

Hello everybody, if I start Avast VPN the external drive in the private home network is not anymore excessable. It looks like a firewall setting. How can the problem fixed? Which settings do I need?

Hi,

Once you are connected to an Avast SecureLine VPN location, please
Open Avast Premium Security and go to Protection > Firewall > and make sure that all active connections are set to “Private Network”
