– If you want to disable NAT, select the Disable radio button. Before disabling NAT, back up
your current configuration settings.
Note: Disabling NAT will reboot the router and reset all the FVL328 configuration
settings to the factory default. Disable NAT only if you plan to install the FVL328 in a
setting where you will be manually administering the IP address space on the LAN side
of the router.
– Internet IP Address (also commonly called the WAN IP address):
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
netmask and the Gateway IP address. The Gateway is the ISP's router to which your
firewall will connect.
– Domain Name Server (DNS) Address:
If you know that your ISP does not automatically transmit DNS addresses to the firewall
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.
A DNS server is a host on the Internet that translates Internet names (such as
www.netgear.com) to numeric IP addresses. Typically your ISP transfers the IP address of
one or two DNS servers to your firewall during login. If the ISP does not transfer an
address, you must obtain it from the ISP and enter it manually here. If you enter an address
here, you should reboot your computers after configuring the firewall.
– Router's MAC Address:
This section determines the Ethernet MAC address that will be used by the firewall on the
Internet port. Some ISPs will register the Ethernet MAC address of the network interface
card in your computer when your account is first opened. They will then only accept
traffic from the MAC address of that computer. This feature allows your firewall to
masquerade as that computer by "cloning" its MAC address.
To change the MAC address, select "Use this Computer's MAC address." The firewall
will then capture and use the MAC address of the computer that you are now using. You
should use the one computer that is allowed by the ISP. Or, select "Use this MAC address"
and enter it.
