How to manage pfsense and devices inside the pfsense using tailgate

Hey i just installed tailscale in pfsense and set it up everything but still not able to access the pfsense gui.
I am familiar with pfsense but not with tailscale and really dont know how to access the pfsense webgui and few of my servers in the network using it.

Also I had watched toms video but really can’t figure out my usecase.
So can anyone help me ??

My remote device<<Tailscale<>Servervlan
My remote device<<Tailscale<<Pfsense Webgui
This is what i want to do

@LTS_Tom can you please help

Make sure you have a firewall rule to allow web UI access under the Firewall → Rules → Tailscale
