Configuring Active/Active HA PAN-OS 4.0
Service providers and enterprises that deliver revenue-generating and business critical services over the Internet face a myriad of performance and security challenges. However critical those challenges may be, high availability remains the paramount concern. In order to properly perform access control functions, a network firewall must be placed at the single point through which all traffic must pass. Because all traffic must pass through the firewall, it is vital that the traffic flow remains uninterrupted, even in the event of a device or network failure. A well-designed security infrastructure needs to offer high availability tools to create a resilient, scalable, and easy to manage solution.
Palo Alto Networks offers a line of purpose-built security solutions that integrate firewall and VPN functions with a set of high availability (HA) tools to deliver resilient, high performance devices. This technical paper describes the main functionality of PAN-OS high availability
