Configuring Active NSv Firewall Using the Associated Public IP

Once you are logged in, register the appliance first. After the registration, follow the steps below.

1. Navigate to Network > System > Interfaces. Change the X0 configuration first, and then X1, as shown below. You will lose access after you change X1.

   

   

2. Before changing the X1 Interface IP, take a screenshot of the current configuration. The Default Gateway and DNS Server 1 should remain the same and ensure you won’t lose access to the active firewall during the following steps.

3. After the changes, the Interfaces should look similar to the screenshot below:
