New to CGNAT and overlay networks like tailscale.
I set up a remote network with a T-Mobile Home Internet service which is configured as WAN1 on my PFSense Netgate 2100 firewall router. Trying to at least get connected remotely to the pfsense web UI.
A few days ago when I was at the site, I seemed to have remote capabilities when I used my android mobile hotspot and was able to access pfsense on its internal IP address. The WiFi on my laptop was connected to my hotspot.
I have installed the latest Tailscale package into PFSense with non-reusable key and advertising the local route. Also, enabled.
Yesterday I got a notification that pfsense had rebooted although I don’t know why. But I know it is on and basically running. Movies are being streamed and everyone is delighted.
I can tailscale ping
and I get a series of connections but at the bottom it shows direct connection not established. My understanding is that I will get DERP if no direct connection. But cannot connect to pfsense with http/https, etc.
# tailscale ping 192.168.1.1

direct connection not established
When I execute a normal ping I get nothing, then a timeout.
In the Machines tab of tailscale it shows a green dot indicating that it is connected and working.
Also, from my local home Ubuntu laptop, I get the following:
# tailscale status
