I am running a node application that uses webpack. The application starts and automatically selects the port 8080 on localhost:
The website works correctly on the browser on my machine. I want now to allow others to access it.
For this I want to make sure the port
8080 is reachable, so I add a firewall exception:
sudo uwf status
I check that the application is listening correctly:
sudo ss -tulpn | grep LISTEN
Then when I do nmap, the port scan fails for
8080 on my own VPN address.
sudo nmap 10.8.1.66 -p 8080
How should I troubleshoot this? Is this OpenVPN blocking the traffic?
