Dynamic DNS
If your Internet service provider (ISP) gave you a permanently assigned IP address, you can 
register a domain name and have that name linked with your IP address by public Domain 
Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP 
address, you do not know in advance what your IP address is, and the address can change 
frequently. In this case, you can use a commercial Dynamic DNS service. This type of service 
lets you register your domain to their IP address and forwards traffic directed at your domain 
to your frequently changing IP address.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic 
DNS service does not work because private addresses are not routed on the Internet.
Your modem router contains a client that can connect to the Dynamic DNS service that 
DynDNS.org provided. First visit their website at http://www.dyndns.org and obtain an 
account and host name that you configure in the modem router. Then, whenever your 
ISP-assigned IP address changes, your modem router automatically contacts the Dynamic 
DNS service provider, logs in to your account, and registers your new IP address. If your host 
name is hostname, for example, you can reach your modem router at 
http://hostname.dyndns.org.
To set up Dynamic DNS:
1. Launch a web browser from a computer or wireless device that is connected to the 
network.
2. Type http://routerlogin.net or http://192.168.0.1.
A login screen displays.
3. Enter the modem router user name and password.

der gave you.
9. T

log in to your account, not your host name.

Improve Network Connections with Universal Plug and 
Play
Universal Plug and Play (UPnP) helps devices, such as Internet applian\
ces and computers, 
access the network and connect to other devices as needed. UPnP devices \
can 
automatically discover the services from other registered UPnP devices o\
n the network.
If you use applications such as multiplayer gaming, peer-to-peer connect\
ions, or real-time 
communications such as instant messaging or remote assistance (a featur\
e in Windows XP), 
enable UPnP

.
To enable Universal Plug and Play:
1. Launch a web browser from a computer or wireless device that is connecte\
d to the 
network.
2.  T
ype  http://routerlogin.net  or http://192.168.0.1.

The user name is  admin. 
 The default password is password . The user name and 
password are case-sensitive.
The BASIC Home screen displays.
4.  Select  ADV
 ANCED > Advanced Setup > UPnP .
5. Select the  Turn UPnP On check box.
By default, this check box is selected. If the T
 urn UPnP On check box is cleared, the 
modem router  does not allow any device to automatically control router resources, suc\
h 
as port forwarding.
6.  T
ype the advertisement period in minutes.
The advertisement period specifies how often the modem router  broadcasts its UPnP 
information. 
 This value can range from 1 to 1440 minutes. The default period is 30 
minutes. Shorter durations ensure that control points have current devic\
e status at the 
expense of more network traffic. Longer durations can compromise the freshness of the 
device status, but can significantly reduce network traffic.
7.  T
ype the advertisement time to live in hops.
The time to live for the advertisement is measured in hops (steps) for\
 each UPnP packet sent. Hops are the steps a packet takes between routers. 
 The number of hops can range 
from 1 to 255. The default value for the advertisement time to live is 4 hops, which sh\
ould 
be fine for most home networks. If you notice that some devices are not \
being updated or 
reached correctly, it might be necessary to increase this value.
8.  Click the  Apply button.
The UPnP Portmap Table displays the IP address of each UPnP device that is accessing  the modem router  and which ports (internal and external) that device has opened. 

The 
UPnP Portmap Table also displays what type of port is open and whether that port is st\
ill 
active for each IP address.
9.  T
o refresh the information in the UPnP Portmap Table, click the  Refresh button.
