UFW firewall generator

Enter the ports and get the UFW commands in the right order, with an SSH check.

What does this mean?

UFW is the simple firewall for Ubuntu and Debian. Specify the ports that need to be open; you'll get the commands in the right order, with SSH checks so you don't lock yourself out.

Then test the rules with our port checker. Docker bypasses UFW for published ports. More: the UFW cheat sheet.
