I recently converted from opnsense and installed the Tailscale package. I then started the service, added the interface, authenticated the router on Tailscale as a new device and added a firewall rule to allow all Tailscale traffic. I can see on opnsense that the device is connected to my Tailscale network under the status page. I have also allowed and approved use of subnet routes for the router. I however cannot connect remotely to the opnsense router or any other devices on the network.
Any help appreciated. I followed the instructions below from zenarmor which I thought were pretty good.

I solved my problem. I had not yet approved the advertised subnet I created. I am surprised however that I could not connect to the router/device since it was already approved in Tailscale
