One of our branch offices is connected via an SDSL connection to a Cisco 878, which in turn NAT's a FortiGate 110-C behind it. Obviously, this creates a double-NAT network and is suboptimal.
What I'm trying to achieve is the ability to assign the single public address received from the ISP to the FortiGate's WAN side. My problems are further exacerbated by FortiGate's lack of support for PPPOA dialing (which would simplify issues as I would just bridge the ATM interface).
Is this even possible?
