– Internet IP Address . Determines how your router obtains an IP address for Internet
access.
• If your ISP assigns an IP address dynamically (by DHCP), select Get Dynamically
From ISP .
• If your ISP has assigned you a permanent, fixed (static) IP address for your computer,
select
Use Static IP Address . Enter the IP address that your ISP assigned. Also, enter
the subnet mask and the gateway IP address. The gateway is the ISP’s router to which
your router will connect.
– Domain Name Server (DNS) Address . If you know that your ISP does not automatically
transmit DNS addresses to the router during login, select Use These DNS Servers , and
enter the IP address of your ISP’s primary DNS server. If a secondary DNS server address
is available, enter it also.
– Router MAC Address . This section determines the Ethernet MAC address that the router
will use on the Internet port. Typically, you would leave Use Default Address selected.
However, some ISPs (especially cable modem providers) register the Ethernet MAC
address of the network interface card in your computer when your account is first opened.
They then accept only traffic from the MAC address of that computer. This feature allows
your router to masquerade as that computer by “cloning” or “spoofing” its MAC address.
To change the MAC address, select one of the following methods:
• Select Use Computer MAC Address . The router will then capture and use the MAC
address of the computer that you are now using. You must be using the one computer
that is allowed by the ISP.
• Select Use This MAC Address , and enter it here.
Note: If you enter or change a DNS address, restart the computers on your
network so that these settings take effect.
