I do this (I think) with a Conexant unit. The ADSL router has a routable 
IP on the external connection, and a non-routable one on the internal. 
The gateway/firewall has THE SAME IP on its external interface 
(connected to the router by ethernet) and a routing rule to access the 
router's internal address. The upshot is that only the gateway needs to 
do NAT and port forwarding etc as the router simply hands over all 
packets. A down side is that it can be somewhat arcane to re-establish 
a connection if the ADSL link dies since the router will only talk to 
one box in this config, and then only when it has assigned the IP by 
dhcp with 60second leases. I'd much prefer to have the router be a 
truly transparent bridge.
