I run proxy through RPi3b+ that is installed in another country. I want to open a port on RPi that is being used by qbittorent on main machine which is 6881. Is there any way to do it?
I have used ufw enable 6881/tcp but it seems not to work. And I tried miniupnp but it fails to ind IGD which must be there cause router does have UPnP tailscale port open automatically. Am I doing something wrong?


Eh?
Lookup what Tailscale is. Install it on the remote machine, then access that machine like a VPN would bypassing the router and the public aspect of the networking you’re having issues with.
If instead you’re saying that your ports are NOT actually opening because the service is problematic, then you have a diff problem. Debug and make sure the service you’re expecting to be avai6is ACTUALLY available. Check that the process has the ports open, and check on that remote machine that it can actually connect to those ports.
If so, then just use Tailscale.
How do you think I am accessing rpi3 in another country? Teleporting?
Then you don’t understand networking. Okay.
I’m not sure how to help you since you seem to not understand what I’m telling you. Good luck.
Ok, broski. Have a nice one
