IMPORTANT: Outside users who want to access the X4’s virtual

server need to use the X4’s WAN IP address

(supplied by your ISP), not the LAN IP address. If

you don’t know the WAN IP address, you can

find it by clicking the System Status icon at the

top of the X4’s main interface page and scrolling
down to the WAN Status section.

Note: To test the port forwarding feature, you must use another

person’s dial-up or Internet connection so that you are
accessing the virtual server from outside the network.

In certain instances, you may want to give outside users
unrestricted access from the Internet to one computer on your

LAN. For example, you may want to use an application such as

NetMeeting that uses dynamic ports. Or you may want to use the

computer to play games over the Internet, and you want others to

be able to initiate games with you. Because of the X4’s firewall,

without a DMZ you would always have to be the one to initiate a
game. A DMZ configuration bypasses the modem’s NAT firewall

and allows the computer to accept all incoming packets.

CAUTION! Use the DMZ feature with the utmost care. It

exposes the DMZ computer’s entire contents to the
Internet; there is no firewall protection whatsoever.

To enable the X4’s DMZ feature, follow these steps.

You need to specify the DMZ Host IP address. To obtain

this address, navigate to the LAN Settings page by returning

to the Advanced Setup page and clicking the LAN Settings

button. You’ll see the defined starting and ending LAN IP

address range; for example, 10.0.0.4 and 10.0.0.15. Your DMZ
Host IP Address should be a static IP address outside of this

range—say, 10.0.0.16.
To set this static IP address, go to Start | Settings | Network
and Dial-up Connections. Right-click Local Area
