Creating redundant IPsec VPNs
To use VPN resiliency/redundancy, configure a list of VPN gateways, instead of just one:
This is a balanced but incomplete XML configuration fragment. It includes all closing tags, but omits some important elements to complete the IPsec VPN configuration.
RedundantSortMethod = 1
This XML tag sets the IPsec VPN connection as ping-response-based. The VPN connects to the FortiGate which responds the fastest.
RedundantSortMethod = 0
By default, RedundantSortMethod =0 and the IPsec VPN connection is priority-based. Priority-based configurations try to connect to the FortiGate starting with the first in the list.
