From the MAC Address Clone screen, shown in Figure 6-36, you can change
the Router’s WAN Mac Address.
The Router’s MAC address is a 12-digit code assigned to a unique piece of
hardware for identification, like a social security number. Some ISPs require
that you register the MAC address of your network card/adapter, which was
connected to your cable or DSL modem during installation. If your ISPs
require MAC address registration, find your adapter’s MAC address by doing
the following:
1. Click the Start button, and select Run. Run winipcfg, and then click more
info. Or at the command prompt, run ipconfig/all, and look at your
adapter’s physical address.
2. Enter those 12 digits into the WAN MAC Address fields, and click the
Apply button followed by the Continue button. This “clones” your net-
work adapter’s MAC address onto the Router, and prevents you from hav-
ing to call your ISP to change the registered MAC address to the Router’s
MAC address.

From the DMZ Host screen, shown in Figure 6-35, you can allow one local user
to be exposed to the Internet to use a special-purpose service such as Internet
gaming or videoconferencing.
Whereas IP Forwarding can only forward a maximum of ten ranges of ports,
DMZ hosting forwards all the ports for one PC simultaneously.
•
To expose one PC, enter the computer’s IP address and click the Apply but-
ton and Continue button.
•
Deactivate DMZ by entering 0 in the field and clicking the Apply button
and Continue button.
