The chief task in life is simply this: to identify and separate matters so that I can say clearly to myself which are externals not under my control, and which have to do with the choices I actually control. Where then do I look for good and evil? Not to uncontrollable externals, but within myself to the choices that are my own…
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.
You’ll maintain a healthy diet with this much salad.
