Modem Router Setup

N150 Wireless ADSL2+ Modem Router N150RM
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. Combined with the IP
address, the IP subnet mask allows a device to know which other addresses are local to
it, and which have to be reached through a gateway or modem router.
•
RIP Direction
. Router Information Protocol (RIP) allows a router to exchange routing
information with other routers. This setting controls how the router sends and receives
RIP packets. Both is the default setting. With the Both or Out Only setting, the router
broadcasts its routing table periodically. With the Both or In Only setting, the router
incorporates the RIP information that it receives.
•
RIP Version
. This setting controls the format and the broadcasting method of the RIP
packets that the modem router sends. It recognizes both formats when receiving. By
default, the RIP function is disabled.
RIP-1
is universally supported. It is adequate for most networks, unless you have an
unusual network setup.
RIP-2
carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2
format. RIP-2B uses subnet broadcasting. RIP-2M uses multicasting.
Use Router as a DHCP Server
This check box is selected by default so that the modem router functions as a Dynamic Host
Configuration Protocol (DHCP) server.
•
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 modem router’s DHCP server. Assign
reserved IP addresses to servers that require permanent IP settings. See
Address
Reservation
on page 34.
Use the Modem Router as a DHCP Server
By default, the modem router acts as a DHCP server. The router assigns IP, DNS server, and
default gateway addresses to all computers connected to the LAN. 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 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.
