How Do I Configure My DOCSIS Residential Gateway?

Section

Field Description

 

 

Starting IP Address

 

Displays the starting address used by the built-in DHCP

 

server to distribute Private LAN IP addresses. Because the

 

device default IP address of the gateway is 192.168.0.1, the

 

starting IP address must be 192.168.0.2 or greater, but

 

smaller than 192.168.0.253. The default Starting IP Address

 

is 192.168.0.10.

 

 

 

 

Maximum Number of DHCP Users

 

Enter the maximum number of users to which the DHCP server

 

can assign IP addresses for use in the LAN. This number cannot

 

be greater than 254 minus the starting IP address described

 

above.

 

 

 

 

Client Lease Time

 

The Client Lease Time is the amount of time an IP address is

 

valid. IP address leases are renewed automatically by your PC

 

and other devices that use DHCP to obtain IP addresses. If a lease

 

is allowed to expire, the IP address will be returned to the pool of

 

available IP addresses that can be assigned by the DHCP server

 

as new devices are added to your network. The default is 60

 

minutes when the gateway is online.

 

 

 

 

LAN Static DNS (Domain Name Server) 1-3

 

DNS is used by a PC or other client devices to discover the public

 

IP address associated with a URL or the name-based address of a

 

website. You can manually specify which DNS servers are to be

 

used by devices in your network by entering the IP addresses of

 

those servers in these fields. Otherwise, the gateway will forward

 

the DNCS server information from your service provider

 

automatically. The default is to leave these fields blank.

 

 

 

Time Settings

Time Zone

 

Select the time zone for your location. If your location follows

 

daylight saving time, select Automatically adjust clock for

 

daylight saving time.

 

 

 

Setup > DDNS

Dynamic Domain Name Service (DDNS) provides the residential gateway (that may have a changing IP address) with a host name or URL resolvable by network applications through standard DNS queries. DDNS is useful when you are hosting your own website, FTP server, or other server behind the device. Before using this feature, you need to sign up for DDNS service.

Select the DDNS tab to open the Setup DDNS page.
