Create a redundant IPsec VPN
To use VPN resiliency/redundancy, configure a list of FortiGate IP/FQDN servers, instead of just one:
<forticlient_configuration>
<vpn>
<ipsecvpn>
<options>
...
</options>
<connections>
<connection>
<name>psk_90_1</name>
<type>manual</type>
<ike_settings>
<prompt_certificate>0</prompt_certificate>
<server>10.10.90.1;ipsecdemo.fortinet.com;172.17.61.143</server>
<redundantsortmethod>1</redundantsortmethod>
...
</ike_settings>
</connection>
</connections>
</ipsecvpn>
</vpn>
</forticlient_configuration>
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.
