How Do I Configure the Cable Modem Gateway?
Reserving IP Addresses
Use the Setup Basic Settings - Fixed CPE IP Assignment page to reserve IP
addresses. This feature allows you to assign a fixed IP address to any device in your
network by setting static IP addresses in your PC or other network device.
These addresses will be removed from the pool of the IP addresses to be used by
your gateway's DHCP server when issuing IP addresses to devices that are
connected to your local network.
Reserving IP addresses is useful in making sure that there are no IP address conflicts
on the network, for example, two devices using the same IP address. Another
example: when using DMZ Host, the IP address for the DMZ Host should always
have the same IP address.
Note: If you are not familiar with the Fixed CPE IP Assignment procedures detailed
in this section, contact your service provider before you attempt to change any of the
cable modem gateway default Fixed CPE IP Assignment settings.
Click Fixed CPE IP Assignment in the Basic Settings section of the Setup page to
access the Setup Basic Settings - Fixed CPE IP Assignment page.
