How to open public port on server while running OpenVPN + Pihole app?

Hello! I created an OpenVPN + pinhole 1.1.1 on Ubuntu 18.04 application on my droplet. Now I want to run another application (java app) nearby in this droplet on port 8080. I tried to open ports via ‘ufw allow 8080’ command, but I did not work: can not access java app on http://<droplet_public_id>: 8080 Is it possible to run side apps with OpenVPN + pinhole 1.1.1?

Hi there,

I believe that this should be doable. Are you running your Java app on 0.0.0.0:8080 or on 127.0.0.1:8080?

Note that if it is on 127.0.0.1:80808 then the app would only be accessible via the local network. You can check this with:

netstat -plant | grep 8080

Best,

Bobby
