Configuring Internal Forwarding SettingsThe Virtual Servers function will allow you to route external (Internet) 
calls for services such as a web server (port 80), FTP server (Port 21), 
or other applications through your Router to your internal network. 
Since your internal computers are protected by a firewall, computers 
outside your network (over the Internet) cannot get to them because 
they cannot be “seen”. A list of common applications has been 
provided in case you need to configure the Virtual Server function for 
a specific application. If your application is not listed, you will need 
to contact the application vendor to find out which port settings you 
need.
Choosing an ApplicationSelect your application from the drop-down list. Click “Add”. The 
settings will be transferred to the next available space in the screen. 
Click “Apply Changes” to save the setting for that application. To 
remove an application, select the number of the row that you want to 
remove then click “Clear”.
Manually Entering Settings into the Virtual ServerTo manually enter settings, enter the IP address in the space provided 
for the internal (server) machine, the port(s) required to pass (use a 
comma between multiple ports), select the port type (TCP or UDP), 
and click “Apply Changes”. You can only pass one port per internal IP 
address. Opening ports in your firewall can pose a security risk. You 
can enable and disable settings very quickly. It is recommended that 
you disable the settings when you are not using a specific application.

Setting Client IP FiltersThe Router can be configured to restrict access to the Internet, email, 
or other network services at specific days and times. Restriction 
can be set for a single computer, a range of computers, or multiple 
computers. 
To restrict Internet access to a single computer for example, enter the 
IP address of the computer you wish to restrict access to in the IP 
fields 
(1). Next, enter “80” in both the port fields (2). Select “Both” (3). 
Select “Block” (4). You can also select “Always” to block access all 
of the time. Select the day to start on top (5), the time to start on top (6), the day to end on the bottom (7), and the time to stop (8) on the 
bottom. Select “Enable” (9). Click “Apply Changes”. The computer at 
the IP address you specified will now be blocked from Internet access 
at the times you specified. Note: Be sure you have selected the 
correct time zone under “Utilities> System Settings> Time Zone”.

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 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.
1.  Select  DynDNS.org  from  the  “DNS  Service”  drop-down  box (1).2.  Enter  your  DynDNS.org  user  name  in  the  “User  Name”  field (2).3.  Enter  your  DynDNS.org  password  in  the  “Password”  field (3).4.  Enter  the  DynDNS.org  domain  name  you  set  up  with  DynDNS.org  in  the  “Domain  Name”  field (4).5.  Click  “Update  Dynamic  DNS”  to  update  your  IP  address (5).
Whenever your IP address assigned by your ISP changes, the Router will 
automatically update DynDNS.org’s servers with your new IP address. You 
can also do this manually by clicking the “Update Dynamic DNS” button 
(5).

Blocking an ICMP Ping
Computer 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.
