Adding a new interface to an existing Single Firewall element

An example of adding an interface to a Single Firewall.

In the previous example, the administrator initially configured the firewall at the company’s new branch office with just two interfaces. Now the administrator decides to add a physically separated DMZ network for access to/from that office’s mail server to properly control both internal and external traffic with this publicly exposed server. The administrator:
  1. Creates an interface for the DMZ and gives it the following properties:
    • Interface ID: 2
    • IP Address: 192.168.2.1.
  2. Creates new rules in the firewall’s policy to allow traffic to/from the DMZ and NAT rules to translate between the private and public IP address of the mail server.
  3. Connects the new DMZ router to the firewall.
  4. Installs a Firewall Policy using the Management Client to transfer the new working configuration to the Firewall.
