Afaik to run multiple IPs on one DSL account you must use a DSL modem in bridge
mode and a router or two after that. Most soho routers can handle multiple
connections but not multiple NATs. So the second router would have to be
daisy-chained from the first (which would not do NAT and serve the DMZ with the
server and the workstations directly) and run as afixed IP on the input and NAT
and DHCP on the output to serve the 'inner' network. This will cause the power
workstations in the DMZ to be invisible to the local net. What you are trying to
do fully mandates setting up a dedicated BSD or linux box with 2-3 NICs just to
do the routing and firewalling imho.
