Creating 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 omitted.

RedundantSortMethod = 1

This XML tag sets the IPsec VPN connection as ping-response-based. The VPN connects to the FortiGate that responds the fastest.

RedundantSortMethod = 0

By default, RedundantSortMethod =0, and the IPsec VPN connection is priority-based. Priority-based configuration attempts to connect to FortiGates by starting with the first FortiGate on the configured list.
