I don't quite get it. So what do I need to do for firewalls to stay connected without my intervention?
Yesterday, I upgraded 3 of my firewalls to 25.7 - all three went down. While on 2 of them, simple VPN restart helped and they connected (at least showed IP), one did not. What is funny is - on the tailscale admin page, none of the 3 showed online.
I ended up creating 3 new auth keys and updated them in OPNSense and all 3 suddenly connected.
This happened to me for second time in past month or so.
