I HAVE tried it. When you suggested it.
Works with Express, but although I haven't measured the speed, everything seems noticeably slower.
However, that approach doesn't work with Nordvpn at all. Weird results with Netflix (Most of my stuff was no longer available), Prime knew I was using a vpn, BBC the same. And NORD is much better with some applications than Express, so I really want to use both.
And I tried all sorts of combinations of DNS filtering (not at the same time as setting the DNS as you suggested). That left me with "No connection to the Internet" a lot of the time...
Well the fact ExpressVPN works as desired (the performance issues aside), but NordVPN doesn't, tells me this really isn't a problem w/ the router per se. It's a function of how these websites are reacting to which network interface is being used to access them and/or resolve their domain names. This is a mess brought on by these websites themselves, in their attempt to limit access or implement regional restrictions. And there's no easy way to resolve it other than experiment w/ different DNS servers, VPN providers, etc. The only problem I was trying to resolve was the DNS leaks, which should now be corrected.
