LAN Setup Screen Fields
Use this screen to view or change the LAN setup fields.
LAN TCP/IP Setup
•
IP Address
. The LAN IP address of the modem router.
•
IP Subnet Mask
. The LAN subnet mask of the modem router. When combined with the
IP address, the IP subnet mask allows a device to know the following:
-
Which other addresses are local to it
-
Which other addresses must be reached through a gateway
DHCP IP Pool
•
Starting IP Address
. Specify the start of the range for the pool of IP addresses in the
same subnet as the modem router.
•
Ending IP Address
. Specify the end of the range for the pool of IP addresses in the
same subnet as the modem router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer receives
the same IP address each time it accesses the DHCP server of the modem router. Assign
reserved IP addresses to servers that require permanent IP settings.
Use the Router as a DHCP Server
By default, the modem router functions as a DHCP server. This capability allows the modem
router to assign IP, DNS server, and default gateway addresses to all computers connected
to the LAN that is connected to the modem router. The assigned default gateway address is
the LAN address of the modem router. The modem router assigns IP addresses to the
attached computers from a pool of addresses that are 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 modem router are satisfactory.
You can specify the pool of IP addresses that can be assigned by setting the starting IP
address and ending IP address. These addresses are part of the same IP address subnet as
the LAN that is connected to the modem router. Using the default addressing scheme, you
define a range between 192.168.0.2 and 192.168.0.254. You can save part of the range for
devices with fixed addresses.
The modem 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 LAN IP address of the modem router)
