UFW is the way to go for beginners trying to turn on ports in Ubuntu. But heads up—if you’re behind a router, you might need to forward ports there too.
For local stuff, `sudo ufw allow 8080` works. For external access, check your router settings.
Also, if you’re testing, `nc -lvnp 8080` can help you see if the port’s really open.
