Tailscale Interface?

[EFaden]

So I followed the instructions at https://tailscale.com/kb/1097/install-opnsense#connect, but I'm having an issue with filtering.  When I setup the interface I just have an empty interface with no ip settings.  The filter doesn't seem to do anything though.  If have no filters or a default deny I can still ping everything from the tailscale client on the other side.  Am I missing something?
