I’m spoiled now. I prefer ubiquiti equipment for my network, security camera, and even door access.

However, if you prefer completely open source I can recommend opnsense and openwrt. Personally I prefer a single point of configuration… So all ubiquiti for me… It makes it easy to restore a complete network configuration as you are discovering is a pain.

Maybe start with the new cloud gateway max as a router if you are interested.

You might look at gluetun. It lets you configure various VPN services from a docker container. The interesting part is that you can point other docker containers to utilize gluetun for networking. Essentially piping them through the configured VPN.
