my router is the ac86u and after setting up the tailscale on Windows 10 (For now) it seems to get a connection but uses relay. My isp gives me a static ipv4 address. i don't fully understand why it can't connect to the tailscale directly and even tried port forwarding too. The client device trying to connect to my tailnet is behind cgant so could it be that, when I use tailscale staus is shows relay. Might it be winodws fireall or is it a router issue,
Any help is welcome. Thanks
