I use Comodo Firewall (on windows machines) to give access or deny access to various apps. I have a VPN only web browser and a web browser that only works when the VPN is off. Wireguard is not supported whereas OpenVPN is.

Mullvad is ditching OpenVPN. I don’t use Wireguard since it breaks my firewall rules. AirVPN is decent enough. I have used them for port forwarding before.

If this is you, then build your own home server. Encrypt all the things. Make a stop gap from the Internet. Realize that your personal data is very valuable to predatory groups and governments. Never trust the cloud.

Aniwave shut down too. Same message.
