Opening a port on Ubuntu is straightforward. Use `sudo ufw allow [port_number]` to open the desired port. For RDP, use `sudo ufw allow 3389/tcp`. Confirm the change with `sudo ufw status`. On a residential server, ensure your router forwards the port correctly. This setup is crucial for services like RDPextra. Always consider security when opening ports.
