IPSec tunnel initiation from specific IP

I need to have my IPSec tunnel initiate from a specific IP address on my outside interface. In the IKE gateway | local IP address field I can only select the outside interface IP/subnet and then the tunnel uses that default interface IP as the source. My outside interface has a whole subnet of IP addresses and I want to use a specific one not the default one assigned to the interface. I can't figure out how to get my IPSec tunnel to use the specific outside IP I want it to. The remote site is expecting the connection from this specific IP not the default interface IP.

hi @Scott.Ainslie 

 

In network > Interfaces > loopback, create a new loopback interface and set it to the same zone as your outside interface, then assign it the IP you want to use for your IPSec connection

Next, go into your IKE gateway object and set the local interface to the loopback

commit the change and you're set
