Dear Beloved Zenarmor Users,
High availability (HA) refers to the capacity of an IT system, component, or application to function consistently and without interruption at a superior level for a certain duration. The high-availability architecture is designed to provide optimal performance and effectively manage various workloads and faults while minimizing or eliminating any interruptions in service.
An impressive capability of OPNsense is the ability to establish a redundant firewall with an automated fail-over option. OPNsense employs the Common Address Redundancy Protocol (CARP) to enable hardware failover.
This tutorial will explain how to configure high availability on OPNsense firewall systems.
