Hi
I would like to share with you a project that I created to set up and manage a VPN gateway/proxy to reroute specific internet domains requests to go through a VPN tunnel.
This can help you to access geo-restricted content, access any blocked domains and gives you more privacy.
The app is compatible with Pi Hole 4 and can be installed in the same server (PS: It will require you to change lighttpd port from 80 to anything else for the sniproxy to work)
Check it out and let me know what do you think about it.
