Concentrator
In a hub-and-spoke configuration, policy-based VPN connections to a number of
remote peers radiate from a single, central FortiGate unit. Site-to-site connections
between the remote peers do not exist; however, VPN tunnels between any two of
the remote peers can be established through the FortiGate unit “hub”.
In a hub-and-spoke network, all VPN tunnels terminate at the hub. The peers that
connect to the hub are known as “spokes”. The hub functions as a concentrator
on the network, managing all VPN connections between the spokes. VPN traffic
passes from one tunnel to the other through the hub.
You define a concentrator to include spokes in the hub-and-spoke configuration.
To define a concentrator, go to VPN > IPSEC > Concentrator.

Defining concentrator options
A concentrator configuration specifies which spokes to include in an IPSec hub-
and-spoke configuration.
To specify the spokes of an IPSec hub-and-spoke configuration, go to VPN >
IPSEC > Concentrator and select Create New.
