How do you limit a connection in UFW?

How to set UFW block rules for incoming only?
To set these block rules for incoming only, you would use sudo ufw deny in 1:22/tcp for example. Alternatively, set for outgoing sudo ufw deny out 1:22/tcp and so on.

How can I stop UFW on my computer?
You can use systemd to control UFW, but it has its own controls that are easier. Start by enabling and starting up UFW. Now stop it. This simultaneously disables it during startup. When you want to check if UFW is running and which rules are active, you can.

How can I check if UFW is running?
When you want to check if UFW is running and which rules are active, you can. Start off with a basic command. Allow inbound HTTP traffic. This is necessary if you want to view a website or download anything from the Internet. Try it again with SSH. Again, this is super common. You can do the exact same thing using port numbers, if you know them.
