Using The Gateway As A Dhcp Server - NETGEAR CG814W Reference Manual

The gateway is shipped preconfigured to use private IP addresses on the LAN side, and to act as a
DHCP server. The gateway's default LAN IP configuration is:
• LAN IP addresses—192.168.0.1
• Subnet mask—255.255.255.
These addresses are part of the IETF-designated private address range for use in private networks,
and should be suitable in most applications. If your network has a requirement to use a different IP
addressing scheme, you can make those changes in this menu.
The LAN TCP/IP Setup parameters are:
• LAN IP Address
This is the IP address of the gateway.
• Subnet Mask
This is the LAN Subnet Mask of the gateway. Combined with the IP address, the Subnet Mask
allows a device to know which other addresses are local to it, and which must be reached
through a gateway or router
Note: If you change the LAN IP address of the gateway while connected through the
browser, you will be disconnected. You must then open a new connection to the new IP
address and log in again.

Using the Gateway as a DHCP Server

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 router'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
how to assign IP addresses for your network.
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, select NO for the DHCP Server, otherwise leave Yes
selected.
