Create a redundant IPsec VPN
To use VPN resiliency/redundancy, configure a list of FortiGate IP/FQDN servers, instead of just one:
This is a balanced, but incomplete XML configuration fragment. All closing tags are included, but some important elements to complete the IPsec VPN configuration are committed.
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 tries to connect to the FortiGate starting with the first on the list.
