I have a Cisco 877 Wireless Router, i also have access to a subnet providing 5 IP addresses (i dont have it yet but will be provided with it soon).
I was wondering what is involved in setting one of the 5 IP's to interface FE0 (one of the LAN ports), and a different one to the wireless interface, i would also like the wireless to provide DHCP to clients... however i want DHCP turned off on interface FE0, so basically i want a DMZ, where people can freely connect to the wireless router (with WPA key ofcourse), they can then VPN through the other IP address to access the server (SBS 2K3) if needed.
I want to keep wireless and the LAN as completely seperate as possible for security reasons.
Is what i am proposing possible? i have some Cisco experience (am 1/2 way through CCNA) but am not really confident!
