Using Dynamic DNS
The Dynamic DNS service allows you to alias a dynamic IP address 
to a static host name in any of the many domains DynDNS.org offers, 
allowing your network computers to be more easily accessed from 
various locations on the Internet. DynDNS.org provides this service, 
for up to five host names, free to the Internet community.
The Dynamic DNS
SM service is ideal for a home website, file server, or 
to make it easy to access your home PC and stored files while you’re 
at work. Using the service can ensure that your host name always 
points to your IP address, no matter how often your ISP changes 
it. When your IP address changes, your friends and associates can 
always locate you by visiting yourname.dyndns.org instead!
To register free for your Dynamic DNS host name, please visit 
 
http://www.dyndns.org.
Setting up the Router’s Dynamic DNS Update ClientYou must register with DynDNS.org’s free update service before  
using this feature. Once you have your registration, follow the 
directions below.

in  the  “Domain  Name”  field (3).
4.  Click  “Update  Dynamic  DNS”  to  update  your  IP  address.
Whenever your IP address assigned by your ISP changes, the Router will

Blocking an ICMP PingComputer hackers use what is known as “pinging” to find potential 
victims on the Internet. By pinging a specific IP address and receiving 
a response from the IP address, a hacker can determine that 
something of interest might be there. The Router can be set up so it 
will not respond to an ICMP ping from the outside. This heightens your 
Router’s security level.
To turn off the ping response, select “Block ICMP Ping” 
(1) and click 
“Apply Changes”. The Router will not respond to an ICMP ping.
Utilities
The “Utilities” screen lets you manage different parameters of the 
Router and perform certain administrative functions.
