As in the title. I’m following the instructions here: Mullvad Port Forwarding. Things were working up until Step 4: Test your port forwarding where it told me that
Port is unreachable. So, I tried their advice on Test your port forwarding#Linux. I followed the instruction
sudo ufw allow X and allowed the port that was given to me by Mullvad. That worked fine, but when I tried to run
nc -l -p X, I run into
Error: Couldn't setup listening socket (err=-3). I tried running
nc -vvv -l -p X, but the only information I get is
Error: Couldn't setup listening socket (err=-3). The port is in use, but that’s kind of the point, right?
Am I doing something obviously wrong?
