Creating redundant IPsec VPNs

To use IPsec VPN resiliency/redundancy, configure a list of VPN gateways within the <server> tag, separating entries with semicolons, then specify a sort method with the <redundantsortmethod> tag:

<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. The fragment includes all closing tags, but omits some important elements to complete the VPN configuration. For a list of all available elements, see the FortiClient XML Reference Guide.

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.
