Reference Manual for the Model DG814 DSL Modem Internet Gateway
6-8 Advanced Configuration of the Gateway
DHCP
By default, the gateway will function as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the gateway's LAN. The assigned default gateway address is the LAN address of the gateway. IP
addresses will be assigned to the attached PCs from a pool of addresses specified in this menu.
Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the gateway are satisfactory. See
“IP Configuration by DHCP ” on page B-10 for an explanation of DHCP and information about
how to assign IP addresses for your network.
Use router as DHCP server
If another device on your network will be the DHCP server, or if you will manually configure the
network settings of all of your computers, clear the ‘Use router as DHCP server’ check box.
Otherwise, leave it checked.
Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP
Address. These addresses should be part of the same IP address subnet as the gateway’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.0.2 and
192.168.0.253, although you may wish to save part of the range for devices with fixed addresses.
The gateway will deliver the following parameters to any LAN device that requests DHCP:
• An IP Address from the range you have defined
• Subnet Mask
• Gateway IP Address (the gateway’s LAN IP address)
• Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the gateway’s LAN IP address)
• Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu
LAN TCP/IP Setup
The LAN IP parameters are:
• IP Address
This is the LAN IP address of the gateway.
