Route-based VPNs help to simplify the implementation of VPN tunnel redundancy. You
can configure several routes for the same IP traffic with different route metrics. You can
also configure the exchange of dynamic (RIP, OSPF, or BGP) routing information through
VPN tunnels. If the primary VPN connection fails or the priority of a route changes through
dynamic routing, an alternative route will be selected to forward traffic through the
redundant connection.
A simple way to provide failover redundancy is to create a backup IPSec interface. You
can do this in the CLI. For more information, including an example configuration, see the
monitor-phase1 keyword for the ipsec vpn phase1-interface command in the
FortiGate CLI Reference.
Optionally, through the CLI, you can define a specific default route for a virtual IPSec
interface. For more information, see the default-gw keyword for the
vpn ipsec phase1-interface command in the
You can configure two VPN peers (or a FortiGate dialup server and a VPN client) to
generate unique Internet Key Exchange (IKE) keys automatically during the IPSec
phase 1 and phase 2 exchanges.
When you define phase 2 parameters, you can choose any set of phase 1 parameters to
set up a secure connection for the tunnel and authenticate the remote peer.
Auto Key configuration applies to both tunnel-mode and interface-mode VPNs.
To configure an Auto Key VPN, go to VPN > IPSEC > Auto Key (IKE).
