Trying to connect a Tailscape instance on a GL.Inet Router to another site

I bought a A1300 with latest 4.4.6 firmware and want establish following connection - is this possible?

I have a client which is connected to the GLInet router via Wifi. The client has no tailscale installed.
Can the client use the tailscale connection of the GLInet router to reach the docker server? I can access the docker server from other devices which have tailscale installed - So basically my question is if the GLInet router can route the requests/traffic from his local WIFI into tailscale to enable a connection between the device without tailscale and the docker server.
