i have a wireless n WRT120N that im using on a business network with 20+ computers and printers. its handling DHCP with all the wired connections which are all staff/employee computers. i want customers to be able to come in and hook up wirelessly without access to our LAN. i understand this can be accomplished using DMZ or duel band. i know this router doesnt support duel band, but im wondering if i can set this up with DMZ. i have found the DMZ option in the router but i dont want to have to configure each customers IP when the come in. i would like them to come in, connect, and be filtered to 'internet only'. question: can i set DHCP to assign a certain IP range to all wireless connections then set that range up on DMZ? or just make all wireless connections DMZ? or is this beyond the capability of this router?
