To access the Wireless Barricade’s management interface, enter the Wireless Barricade IP address in your Web browser http://192.168.2.1. Then click LOGIN. (By default, there is no password.) The home page displays the Setup Wizard and advanced Setup options.
Advanced setup supports more advanced functions like hacker attack detection, IP and MAC address iltering, intrusion detection, virtual server setup, virtual DMZ hosts, and other advanced functions.
If you have a client PC that cannot run an internet application properly from behind the firewall, then you can open the client up to unrestricted two-way Internet access. Enter the IP address of a DMZ host to this screen. Adding a client to the DMZ may expose your local network to a variety of security risks, so only use this option as a last resort.
EDIT: Took me a bit longer then Matty to type this. Oh well, may still be usefull.
