It doesn’t make sense to me to expose it to the tailnet even with ACL, on opnsense there is a bug where it would request re-authentication on each restart so that’s an added negative for me when it comes to adding it.

But what exactly do I benefit from adding the firewall directly part of the tailnet? It’s kinda weird when you think about it, this bad boy is the highest tier device where internet comes from and having it to connect to my homelab that depends on it for internet and having the firewall depend on the homelab for tailscale
