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.

Select the URL for your Dynamic DNS service provider . For example, if your Dynamic DNS service provider is DynDNS.org, select \ www .dyndns.org . 8. T ype the host name (or domain name) that your Dynamic DNS service provi\ der gave you. 9. T ype the user name for your Dynamic DNS account. This name is the name that you use to log in to your account, not your host name. 10. T ype the password (or key) for your Dynamic DNS account. 11. Click the Apply button. Your configuration is saved. 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 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.
