VPN Setup Wizard supports device groups

FortiManager VPN Setup Wizard supports device groups, allowing you to optimize a large number of firewalls as spokes in a VPN community.

When a device group is used in a VPN topology, FortiManager resolves the device group to individual members, and then applies the same logic to generate Phase1/Phase2 information. Keep the following restrictions in mind:

  • VPN Manager only supports the use of device groups for the following hub and spoke topologies: star and dialup.
  • VPN manager only supports the use of device groups for devices in the spoke role.

This document provide a sample configuration of hub and spoke (star topology) with VPN Manager and a device group.

Following is a summary of how to use device groups:

  1. Create device groups. See Creating device groups.
  2. Create protected subnet firewall addresses for hub and spoke devices. See Creating protected subnet firewall addresses.
  3. Create a VPN community. See Creating VPN communities.
  4. Add spoke FortiGate units to the VPN community. See Adding spoke FortiGate units to the VPN community.
  5. Add the hub FortiGate units to the VPN community. See Adding the hub FortiGate unit to the VPN community.

    The hub and spokes are created.

  6. Install VPN configuration and firewall policies to hub and spoke devices. See Installing firewall policies to hub and spoke devices
