Guidelines and limitations for VPN load balancing

Review these guidelines and limitation before configuring VPN load balancing:

Guidelines

  • Enable VPN load balancing explicitly, as it is disabled by default.

  • Include a minimum of two Firewall Threat Defense devices in a load-balancing group.

  • Add only co-located devices to a load-balancing group.

  • Configure the identity certificate on each device with a SAN or wildcard.

Limitation

If a member or director device goes down, the device drops all VPN connections. Re-initiate your VPN connections to restore service.
