Using the Gateway as a DHCP Server
By default, the gateway functions as a DHCP 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. The gateway assigns IP addresses to the
attached computers from a pool of addresses specified in this screen. 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. Click
the link to the online document
“ITCP/IP Networking Basics” in Appendix B for an explanation of
DHCP and information about how to assign IP addresses for your network.
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 192.168.1.2 and
192.168.1.254, although you might wish to save part of the range for devices with fixed addresses.
The router delivers 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 router’s LAN IP address)
• Primary DNS server (if you entered a primary DNS address in the Basic Settings screen;
otherwise, the router’s LAN IP address)
• Secondary DNS server (if you entered a secondary DNS address in the Basic Settings screen)
To use another device on your network as the DHCP server, or to manually specify the network
settings of all of your computers, clear the
Use Router as DHCP Server
check box. Otherwise,
leave it selected. If this service is not selected and no other DHCP server is available on your
network, you need to set your computers’ IP addresses manually or they will not be able to access
the router.
