That’s true. I didn’t really think much when I said that, but it wouldn’t help here. It is still working though, as far as I can tell.

Watch the stars on FlareSolverr soar.

I am attempting to solve this via firewall. I block all RFC1918 source traffic on the LAN interface but allow all traffic on the VPN interface. That seems to function reliably. I’ve tested that I can egress while the VPN is active but not at all when it goes down.

If this is not a good solution, let me know, but it seems reliable and doesn’t require any other tooling.

I realize this doesn’t fit your use case since you have other connections you don’t want in the VPN, but I’m still curious if others use this setup.
