Note
: If you forget the new password, you won't have access to the Configuration
Manager and will need to,
restore the router to its factory settings
thus losing any
changes you made to your router's configuration. To avoid this problem, we
recommend that you write the new password and save it in a convenient location.
Configuring Forwarding Rules
Many applications, such as online games, require you to allow access through your
firewall to the computers or gaming devices behind your router by opening ports in
order to play the online game.
The
Forwarding Rules
page provides different methods for allowing access to devices
behind your router.
The Virtual Server Page
You can use the
Virtual Server
page to configure a virtual server.
Because your router's firewall filters out unrecognized packets to protect your network,
all computers behind this product are invisible to the outside world. If you want, you

can make some of them accessible by enabling
Virtual Server
mapping.
A virtual server will allow access to your computer on certain ports. A port is like a
channel that is used by applications (such as games) to communicate on. For
example, the directions for the game you want to play over the Internet might tell you
to open port 6000.
•
Service Ports
This is the port number you want to allow access to your computer on. To
enter multiple ports use the dash format; for example, 2004-2009.
•
Server IP
This is the IP Address of the computer or gaming device that you want to
allow access to. If you do not know the IP address you can look it up by
selecting
Basic Settings > DHCP Server
, then clicking on
Client List
. To make this
virtual server permanent, then you should set up a fixed mapping to your
computer or gaming device on the
DHCP Server
page. Doing this ensures that
your computer will keep the same IP address
•
Protocol
Select
UDP
,
TCP
,
or
Both
depending on what type of protocol your game or
application uses.
•
Enable
Click to enable the Virtual Server
•
Use Rule#
You can enable your virtual server for certain periods of time by assigning it
a
Rule #
. You must first set up the appropriate
Scheduling Rule
. See
The
Schedule Rule and Schedule Rule Setting Pages
on page 55 for more
information.
For example, if you have an FTP server (port 21) at 192.168.1.5, a Web server (port
80) at 192.168.1.6, and a game at 192.168.1.7, then you need, at minimum, to specify
the following mapping.

The Port Triggering Page
Port triggering opens an incoming port when your computer is using a specified
outgoing port
for specific traffic. This provides a way for you to automate setting up a
Virtual Server with some applications. You can use the
Port Triggering
page to
configure which packets are allowed access.

The Miscellaneous Page
The
Miscellaneous Page
lets you set up and enable a
DMZ Host
on your network, and
enable
UPnP
settings for software and devices. In this way, specific ports can open for
incoming traffic that must pass through your firewall.
•
Set IP Address of DMZ Host
A
DMZ
(Demilitarized Zone)
Host
is a host without the protection of the
firewall. It allows a computer or gaming system to be exposed to
unrestricted two-way communication for Internet games, video conferencing,
Internet telephony and other special applications. Use caution when using a
DMZ because your firewall no longer protects the computer that is set up as
a DMZ.
•
UPnP setting
This feature is enabled by default. Games and applications that are UPnP
compatible will automatically open ports for you on your router.
Configuring Security Settings
The
Security Setting
page lists six configuration menus on the left pane and provides a
description of the configuration menus at center.
