Connecting the Gateway to the Internet
If you have set your configuration for Dynamic IP, below, then an IP address shown here is an
indication that you have successfully received an IP address from your service provider.
If you have set your configuration to Static IP, below, then the IP address you entered will be
shown here.
For Dynamic IP, the Duration and time of Expiration of the IP address are shown. The IP
address is renewed automatically using DHCP.
2.
Enter your Host Name and Domain Name.
These parameters may be necessary to access your ISP’s services such as mail or news servers.
3.
Select Dynamic or Static IP Address:
If your service provider assigns your IP address automatically through DHCP, select
“Dynamic IP”. If your service provider has assigned you a permanent, fixed (static) IP address
for your PC, select “Static IP”.
If you select Static IP, enter the IP address that your ISP assigned. Also enter the Static IP
Mask (also known as netmask), Gateway IP address and Domain Name Server (DNS)
Addresss.
The Gateway is the ISP’s router to which your gateway will connect.
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 gateway 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 PCs after configuring the gateway.
4.
Cable MAC Address:
Device MAC Address
This section indicates the Cable and Device MAC Address settings of your gateway. If you
have existing cable internet service and are replacing your cable modem you may need to
notify your cable service provider of the Cable MAC Address and/or Device MAC Address of
your gateway in order to obtain service. The CG814M Gateway appears to your service
provider to be a cable modem with a single PC connected to it. The Cable Address is the
equivalent of the cable modem. The Device Address is the equivalent of the PC behind the
cable modem, and can be “cloned”. Cloning allows you to specify the MAC address of the
packets the gateway sends to the internet. If you clone the MAC Address of your PC you will
not have to register the Device Address of your gateway.
To change the Device MAC Address that is used to send traffic to the internet, enter the MAC
address you would like to use in the “Cloned MAC Address” field and check the Enable box.
The MAC Address that is entered by default is the MAC Address of the PC that is accessing
the gateway’s web interface.
