I have a cisco 1841 router with WIC 1 DSU-T1 V2 installed in slot 0.
However we moved our offices and now have a Time Warner Business Class cable modem service which arrives as ethernet from their modem.
What I want to do is use eth 0/0 as a DMZ port for web and mail server and use eth 0/1 for NAT and DHCP for work stations. There is 5 routable IP's in which 4 have been dedicate to servers (mail and web) that would be in the DMZ zone. The last one can be used for the NAT'ed and DHCP stations.

Detail information regarding how many NAT clients is required. Access to the router via telnet or ssh is required. Access via web interface can speed up the configuration.
