Description

This article describes how to use local-ID type IP addresses other than the IP addresses configured in the interface for IPSec VPN.

Scope

FortiGate 7.0 and above.

Solution

Starting FortiGate 7.0, it is possible now to set the local ID IP address that is not configured in the interface selected.

 

Local ID can be used in aggressive mode. 

It may have up to 63 characters that are used in regular expressions.

Local ID is an extra piece of data delivered during phase 1 of negotiation; the remote side may be set up to check for a particular ID to permit connection.

 

From CLI:

 

config vpn ipsec phase1

    set localid-type address

    set localid <IP address>

end

Here, mention an IP address instead of reference x.x.x.x.
