How to Establish VPN Failover using the LB2 VPN or VPN 800/2
This document describes a scenario for testing the VPN Redundancy (or Failover) feature of
the LB2 VPN (with or without requiring a license key) and the VPN 800/2.
What is VPN Redundancy?
VPN Redundancy is similar to the Connection Failover feature on the LB2 VPN and VPN
800/2. The purpose of VPN Redundancy is to provide an automatic backup connection for VPN
traffic.
This is different from just building two VPN tunnels simultaneously, because having 2
concurrent VPNs doesn’t mean that redundancy is present. Redundant VPNs indicates there is a
backup VPN tunnel for the active tunnel. If the active tunnel fails, the backup tunnel will take its
place and keep traffic moving through the tunnel.
There’s no load balance inside VPN tunnels. Load balance is only available for internet traffic.
