When an exit node has been set and a new default route is added, create a new rtable in the default rdomain and add the current default route via its physical interface. When control() is requesting a connection not go through the exit-node default route, we can use the SO_RTABLE socket option to force it through the new rtable we created.

There was a problem hiding this comment.
I'm no OpenBSD expert, but looks plausible! And looks like it doesn't affect any other platforms at least, so LGTM.

do you by any chance know if tailscale already supports fib / tunnelfib, also with rdomain there's also tunnelrdomain for tunnel interfaces if it could support that too that would really be nice |
