High Availability Feature Overview and Configuration Guide

This guide describes the operation of High Availability (HA) on the AR-series firewalls, and how to configure and monitor it.

Organizations are increasingly reliant on their data networks. Network outages can be costly, so designing networks for HA is important. A key element to HA design is to duplicate critical components or functions.

On AR-series firewalls, the HA solution uses duplicate firewalls, so that if one firewall fails the other automatically takes over, providing redundant LAN to WAN connectivity.
