Dynamic DNS
Internet service providers (ISPs) assign numbers called IP addresses to identify each 
Internet account. Most ISPs use dynamically assigned IP addresses. This means that the IP 
address can change at any time. You can use the IP address to access your network 
remotely, but most people don’t know what their IP addresses are or when this number 
changes.
To make it easier to connect, you can get a free account with a Dynamic DNS service that  lets 
 you use a domain name to access your home network. To use this account, you must set 
up the modem router to use Dynamic DNS. Then the modem router notifies the Dynamic 
DNS service provider whenever its IP address changes. When you access your Dynamic 
DNS account, the service finds the current IP address of your home network and 
automatically connects you. 
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.

Set Up Port Forwarding to a Local Server
If your home network includes a server, you can allow certain types of incoming traffic to 
reach the server. For example, you might want to make a local web server, FTP server, or 
game server visible and available to the Internet.
The modem router can forward incoming traffic with specific protocols to computers on your  local 
 network. You can specify the servers for applications and you can also specify a default 
DMZ server to which the modem router forwards all other incoming protocols.
To forward incoming traffic for a default service or application:
1.  Decide 
 which  type  of  service,  application,  or  game  you  want  to  provide.
2.  Find 
the  local  IP  address  of  the  computer  on  your  network  that  will  provide  the  service.
The server computer must always use the same IP address. To specify this setting, use the reserved IP address feature. See Manage LAN IP Addresses on page  75.
