Enabling the Demilitarized Zone (DMZ)
The DMZ feature allows you to specify one computer on your network 
to be placed outside of the firewall. This may be necessary if the 
firewall is causing problems with an application such as a game or 
video conferencing application. Use this feature on a temporary basis. 
The computer in the DMZ is 
NOT
 protected from hacker attacks.

To put a computer in the DMZ, enter the last digits of its IP address in 
the IP field and select “Enable”. Click “Apply Changes” for the change 
to take effect. If you are using multiple static WAN IP addresses, it 
is possible to select which WAN IP address the DMZ host will be 
directed to. Type in the WAN IP address you wish the DMZ host to 
direct to, enter the last two digits of the IP address of the DMZ host 
computer, select “Enable” and click “Apply Changes”.

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 Inter net. DynDNS.org provides this service, 
for up to five host names, free to the Inter net 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 your name.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 Client
You must register with DynDNS.org’s free update service before 
using this feature. Once you have your registration, follow the 
directions below.

(1)

2.
  Enter  your  DynDNS.org  user  name  in  the  “User  Name”  field

5.
  Click  “Update  Dynamic  DNS” 
(5) 
to  update  your  IP  address.

Whenever your IP address assigned by your ISP changes, the Router will 
automatically update DynDNS.org’s servers with your new IP address. You

Blocking an ICMP Ping
Computer hackers use what is known as “pinging” to find potential 
victims on the Inter net. 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.

(1)
To tur n 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.
