1760 DMZ Routing Question
Posted on 2005-04-11
Got a few questions on whether a few things are possible.
Our IP space is currently being renumbered to a /24 and we are looking to establish a firewalled DMZ rather than the completely open DMZ that is their now.
Currently installed is a Cisco 1721 from our ISP that connects to our 1760. I'm wondering if its possible to use the Cisco 4 Port Ethernet Interface and basically setup just 1 port on it to connect to a switch to be used as the DMZ.
Next the ISP assigned the /24 to the inside interface of their router which we can't control. Is there to subnet that /24 so 1 IP goes to the Public interface of the 1760 and the rest goes to the DMZ Port of the 1760 without having the ISP reconfigure their router to use a different mask on their inside interface?
