Configuring an IPsec VPN with ADSL Dynamic IP and range of Static IP's

[NetworkZeus]

Hi all,

Just need some quick advice if possible.

I have a Fortigate 60E configured with PPPoE which is using a BT Business ADSL connection. The WAN interface has a single public IP address and routed to that static IP is a range of public IP's. I have created a IPsec VPN connection fine but I want to use one of the Public IP's from the range instead of IP assigned to the WAN interface what's the best way to configure this.

Thanks 

Matt

You can tell the IPsec connection which external IP to listen to.

In the CLI,

conf vpn ipsec phase1-interface

   edit <name>

      set local-gw 8.1.2.3

Hi Ede,

Thanks for your reply. So I can use one of my public IP's even though its not assigned to a physical or logical interface? Is there no need to create a loopback interface and then reference it?

Thanks

Matt
