Step 2: Install Firewall

  1. Navigate to Servers service and open Software tab

If you see a valid version number under Security - UFW (Uncomplicated Firewall) it means the firewall is already installed on this server and you can skip this step.

Firewall not installed
Firewall is installed

  1. Enable Install/Update Mode toggle for each server that doesn't have UFW installed

  2. Once the sync is complete click Install Uncomplicated Firewall

  3. Installing the firewall on the server requires root privileges too. Provide Root password and click OK

After the installation is complete you should see UFW version on all servers (APP1, APP2, ALB)
