Earlier quoted context omitted.
I use the same setup (mullvad + container proxy) and can't praise it enough. I just keep a mullvad connection open on my router and only route the proxy IPs through it. Great for all kinds of silly GeoIP restrictions, too - in my part of the world, homedepot.com just spits out "access denied", a foodnetwork.com recipe you find in search results just redirects you to the tudiscovery.com homepage, etc.
>"I just keep a mullvad connection open on my router and only route the proxy IPs through it.' I'm interested in your setup. Do you configure your router to have a point to point tunnel with Mullvad then? I didn't know this was a thing. Do you then just have a separate container proxy for each GeoIP region you want to access?
For Geo-IP, unfortunately unless you have some sort of automation to reconfigure the OpenVPN settings on your router - this will only work with 1 configuration. They may be alluding to using the VPN to connect to another country where they're not getting weird as fuck redirects and shit content.
Although just as I wrote that, I'm expecting a dd-wrt/browser addon will probably support this somewhere - or at least as a script on Linux.
