UFW Firewall: How to open a port

When you would like to grant SSH access on a Ubuntu machine, you would need to allow access to port 22. In order to allow access to port 22 you would need to add a rule to ufw to open up access to port 22.

To allow access to port 22 you would need to do the following:

1. Open a new Terminal Window
2. Enter the following command:

   sudo ufw allow 22

3. The typical success message will look similar to the below:

   Rules updated
   Rules updated (v6)

    

4. Replace 22 with your port number that you would like to grant access to.
