The firewall provides NAT.  Assuming that the ADSL connection has an
Internet Service Provider at the other end, you don't need a router; the ISP
provides the routing functions.  You just hook the ADSL modem to the WAN
port of the firewall and the LAN switch to the LAN port of the firewall.

If they have servers that need to be WAN acessible, those need to have a WAN
IP address and be hooked to the DMZ port.  The firewall does provide the
routing functions to direct traffic to the LAN or DMZ ports.
