Private MAC Filter
•Click the Edit MAC Filter Setting button to filter users by entering their physical addresses.
In the MAC Filter Setting screen, enter the MAC addresses that you want to filter in the MAC address fields. The users with the filtered MAC addresses will not be able to access the Internet. Click the Apply button and the Continue button, before closing the window.
Block WAN Requests
•This feature is designed to protect users from Internet hackers and other attacks. When enabled, the Gateway will ignore both unknown TCP and ICMP packets from the WAN side. By enabling the Block WAN Request fea- ture, you can prevent your network from being “pinged,” or detected, by other Internet users. The Block WAN Request feature also reinforces your network security by hiding your network ports. Both functions of the Block WAN Request feature make it more difficult for outside users to work their way into your network.

•This feature allows you to manage or configure the Gateway from a remote location, via the Internet. To enable management through the WAN connec- tion, click Enable, and use port 8080 on the remote PC you are using for remote management.
Remote Upgrade
•This feature allows you to upgrade the Gateway’s firmware from a remote location. To enable Remote Upgrade, click Enable.

Forwarding
Important: This is an Advanced Function. No changes should be made to this tab without a thorough understanding of network concepts.
Port Range Forwarding sets up public services on your network, such as web servers, ftp servers,
You may use this feature to establish a web server or FTP server for Internet users to access. Be sure that you enter a valid IP address; you may need to establish a static IP address with your ISP in order to properly run an Internet server. For added security, Internet users will be able to communicate with the server, but they will not actually be connected. The packets will be forwarded through the Gateway instead. If you need to forward all ports to one PC, see the “DMZ” section.
