Point-to-point VPN using tailscale

Installing and Using OpenWrt
1

Hello,

I wanted to set up a PTP VPN using Tailscale since I cannot use Wireguard because i cant get access to port forwarding in this complex. The purpose is to connect my smart devices to my MQTT server back home. Tail scale works atm but when I try to set it up as a client on "mothership", I lose access to it immediately.
