Integrate the Firewall into Your Management Network
All Palo Alto Networks firewalls provide an out-of-band management port (MGT) that you can use to perform the firewall administration functions. By using the MGT port, you separate the management functions of the firewall from the data processing functions, safeguarding access to the firewall and enhancing performance. When using the web interface, you must perform all initial configuration tasks from the MGT port even if you plan to use an in-band data port for managing your firewall going forward.
Some management tasks, such as retrieving licenses and updating the threat and application signatures on the firewall require access to the Internet. If you do not want to enable external access to your MGT port, you will need to either set up an in-band data port to provide access to required external services (using service routes) or plan to manually upload updates regularly.
The following topics describe how to perform the initial configuration steps that are necessary to integrate a new firewall into the management network and deploy it in a basic security configuration.
The following topics describe how to integrate a single Palo Alto Networks next-generation firewall into your network. However, for redundancy, consider deploying a pair of firewalls in a High Availability configuration.
