N150 Wireless ADSL2+ Modem Router DGN1000
Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the Dynamic DNS service will not work because private addresses are not routed on the Internet.
LAN Setup
The LAN Setup screen allows configuration of LAN IP services such as DHCP and Routing
Information Protocol (RIP). The wireless modem router is shipped preconfigured to use private IP addresses on the LAN side and to act as a DHCP server. The wireless modem router’s default LAN IP configuration is as follows:
• LAN IP address. 192.168.0.1
• Subnet mask. 255.255.255.0
These addresses are part of the private address range designated by the Internet
Engineering Task Force (IETF http://www.ietf.org/ ) 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 the LAN IP Setup screen.
Note: If you change the LAN IP address of the wireless modem router while connected through the browser, you are disconnected. To reconnect, open a new connection to the new IP address and log in.
To set up the LAN:
1. Select Advanced > LAN Setup.
2. Enter the LAN Setup configuration and click Apply to save your changes.

IP Address. The LAN IP address of the wireless modem router.
IP Subnet Mask. The LAN subnet mask of the wireless 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 wireless modem router.
RIP Direction. RIP allows a wireless modem router to exchange routing information with other routers. The RIP Direction selection controls how the wireless modem router sends and receives RIP packets. The default setting is Both.
• When set to Both or Out Only, the wireless modem router broadcasts its routing table periodically.
• When set to Both or In Only, the wireless modem router incorporates the RIP information that it receives.
• When set to None, the wireless modem router does not send any RIP packets and ignores any RIP packets received.
RIP Version. This controls the format and the broadcasting method of the RIP packets that the wireless modem router sends. It recognizes both formats when receiving. By default, this is set for RIP-1.
• RIP-1. This version is universally supported. It is probably adequate for most networks, unless you have an unusual network setup.
• RIP-2. This version carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 format.
• RIP-2B. This version uses subnet broadcasting.
• RIP-2M. This version uses multicasting.
Access Router Interface on Additional Port
When NAT is disabled, the wireless modem router’s management interface might be accessed at the wireless modem router’s LAN address using the port number you enter. This feature is not available when NAT is enabled.
Use Router as DHCP Server
By default, the wireless modem router functions as a Dynamic Host Configuration Protocol
(DHCP) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the wireless modem router’s LAN. The assigned default gateway address is the LAN address of the router. IP addresses are assigned to the attached PCs 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 router are satisfactory.

Reserved IP Addresses Setup
When you specify a reserved IP address for a computer on the LAN, that computer always receives the same IP address each time it accesses the router’s DHCP server. Reserved IP addresses should be assigned to servers that require permanent IP settings.
To reserve an IP address:
1. Select Advanced > LAN Setup and click the Add button.
2. In the IP Address field, type the IP address to assign to the computer or server. Choose an
IP address from the router’s LAN subnet, such as 192.168.0.x.
3. Type the MAC address of the computer or server.
Tip: If the computer is already present on your network, copy its MAC address from the Attached Devices screen and paste it here.
4. Click Apply to enter the reserved address into the table.
Note: The reserved address is not assigned until the next time the computer contacts the router’s DHCP server. Reboot the computer or access its IP configuration to force a DHCP release and renew.
To edit or delete a reserved address entry:
1. Click the button next to the reserved address that you want to edit or delete.
2. Click Edit or Delete.
