I set tailscale subnet router on Ubuntu and connected a home router to the Ubuntu machine via USB to an ethernet cable in order to use the router as a gateway to my subnet router. Then I connected an IP camera to the router. So it looks like this physically: IP camera->home router->Ubuntu->Internet
Network interfaces on the Ubuntu are enp0s25(ethernet where I get the internet), and enx60a4b7c211c7(USB to ethernet). When I connect the router via USB to ethernet, I shared enp0s25 to enx60a4b7c211c7 by creating a shared profile and selecting Shared to other computers. this USB Ethernet connection gets 10.42.0.1 IP automatically, so I created a tailscale subnet router 10.42.0.0/24 on the Ubuntu machine.
Everything seems working but when I ping the IP camera from a remote tailscale node, it shows the destination port unreachable. what can I do to make it work?
thank you in advance for your reply.
