VDSL Router - Passing through to Fortigate WAN Port

Hi there,I've got a Telecom provided PACE V5542 Router terminating my VDSL connection.Currently the firmware on these devices doesn't support passing through the Public IP to another device (i.e. my Fortigate Firewall's WAN port)Can anyone recommend a router that will do this for me reliably?My experience has historically been with a range of static IP's say a /28 range, and then you have the DSL type device as a gateway for the WAN interface and route traffic that way. In this instance, as there is only a Single /32 static IP, i have to have that IP come through to the WAN port on the Fortigate.I hope this makes sense...Any advice gratefully received!
