Rethink (since a year ago) has had the ability forward connections per-app to multiple WireGuard upstreams at the same time.

https://old.reddit.com/r/rethinkdns/comments/15r1eq9/v055_mu... / https://archive.md/RqUPe (to us, it turned out to be a deceptively difficult thing to integrate with the rest of the firewall).

Not really on topic, but is there any plan on integrating tailscale with it? There's a userspace mode for tailscale that exposes a socks proxy, but you currently have to spawn that with Termux or another terminal, then forward your traffic on Rethink.

Yes (short of anyone sponsoring us to implement it immediately) we do plan to add tsnet support (https://github.com/celzero/rethink-app/issues/1047) once we iron out existing issues with WireGuard.

I'm unsure if we'd be able to support all of Tailscale's features as easily (taildrop, exit nodes etc), we'll see.
