you must click the Save Changes button and then the
Write Settings to Flash and Reboot button. A
Confirm page displays; click the button to complete the
process. If not, any changes will be lost when you
navigate to another page.
Using Phone Filters
You should use a filter with each device—phone, fax machine,
analog modem, etc.—that is sharing the DSL-enabled line, because
this prevents the device from receiving noise when the DSL
modem is on. Your X4 modem includes an onboard filter, so you
can plug a phone or other device directly into the X4’s PHONE
jack if you like. Plugging a device into this jack is optional, not
required. Tip: If your package includes a two-jack filter, you should
plug your telephone into the filter’s PHONE end, rather than the
X4’s PHONE jack.
For other devices on the DSL-enabled line, plug the device’s phone
cord into the filter’s PHONE end, and plug the filter’s LINE end
into the wall jack. Some X4 models come with filters, and more can
be purchased from a retailer or service provider.
Now that your modem is installed and appropriate filters are
attached, you’re done. Enjoy using the X4.

2.4 NAT Firewall
The X4’s built-in NAT (Network Address Translation) firewall
provides a good, but not perfect, level of protection from
unauthorized access. NAT keeps private a network’s internal IP
addresses and presents to the Internet a set of public IP addresses.
NAT’s more robust counterpart, NAPT (Network Address Port
Translation), replaces a network’s private IP addresses with a single
public IP address. Both NAPT and NAP are transparent to end
users.
Your X4’s NAT firewall is enabled by default; the default setting is
dynamic NAPT—everything is automatic. You shouldn’t need to
change this setting. However, if your service provider instructs you
to disable it (or change it), go to the Advanced Setup page and
click the NAT button.
NAT
Default is NAPT. Options are Disable and NAT. You
should not need to change this setting, unless
advised to do so by your provider. Note: If you
select Disable, all your modem’s firewall capabilities
are turned off.
Session Name
Only applicable to NAT; user-definable name to
differentiate between different NAT sessions,
different PPP sessions, and different PVCs.
User’s IP

X4 ADSL Modem User’s Manual
2.5 Virtual Server
To use certain special applications—some Internet games,
videoconferencing, and Internet telephony, for example—you may
have to use nonstandard ports. A port is an endpoint to a logical
connection. The port number identifies the logical channel being
used—for instance, port 21 is associated with FTP (File Transport
Protocol). If you want to use an application that requires access to
a port that the X4 would normally deny, you have to modify the
X4’s settings to accommodate it.
One way to do this is to implement a virtual server. In other cases,
you might want to have multiple ports open and for this you need
to set up a Demilitarized Zone (DMZ); see page 26 for instructions
on configuring a DMZ.
Tip:We recommend that you visit this web site:
www.practicallynetworked.com/sharing/specialapps.htm.
This site contains easy-to-understand instructions about
opening ports and accommodating special applications.
To set up a virtual server, from the Advanced Setup page, click
the Virtual Server button.
Chapter 2: Advanced Setup Options
23
ID
The ID number is a convenient way to refer
to a particular computer.
Public Port
Outbound port.
Private Port
Inbound port.
Port Type
Default is TCP. UDP is optional.
Host IP Address
IP address from the LAN side of the
computer.
An example will help to illustrate how to set up a virtual server. If
you wanted to use your computer as an FTP server, for instance,
you would follow these steps.

Select an ID number that you want to associate with this
computer—1, for example. (You can set up multiple virtual
servers.)
The inbound and outbound port numbers for FTP are the
same: 21. Enter 21 in the Public Port and Private Port fields.
Select the Port Type. For FTP, it is TCP, which is the default.
Click Add This Setting (in this case, there is no Save
Changes button), and then click Write Settings to Flash and
Reboot.
You need to enter the Host IP Address.
To obtain this address, navigate to the LAN Settings page by
returning to the Advanced Setup page and clicking LAN.
You’ll see the defined starting and ending IP address range; for
example, 10.0.0.3 and 10.0.0.14. Your Host IP Address should
be a static IP address outside of this range—say, 10.0.0.15.
To set this static IP address, go to Start | Settings | Network
and Dial-up Connections. Right-click Local Area
Connection, select Properties, highlight your NIC card’s
TCP/IP entry and click Properties. Click the radio buttons
Use the following IP address and Use the following DNS
server addresses, enter the following data, and click OK.

2.6 DMZ
In certain instances, you may want to give one computer on your
LAN unrestricted Internet access. 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. Without
a DMZ, you would always have to be the one to initiate a game. A
DMZ configuration allows the computer to accept all incoming
packets that it has solicited.
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.

the Advanced Setup page and clicking the LAN Settings
button. You’ll see the defined starting and ending IP address
range; for example, 10.0.0.3 and 10.0.0.14. Your DMZ Host IP
Address should be a static IP address outside of this range—
say, 10.0.0.15.

WAN side HTTP server
Disabled by default.
HTTP server port
Port number with Web access; for ex., if
you change it to 1001, the HTTP server
address on the LAN side would be
http://10.0.0.2:1001.
DHCP Relay
Disabled by default. Enabling this feature
forces all local PCs’ DHCP requests to be
forwarded to the WAN DHCP server.
Important: Be sure to disable the LAN
DHCP server (navigate back to the
Advanced Setup page and LAN Settings
to do so; see page 20 for instructions).
IGMP Proxy
Disabled by default. Select enable, then
navigate back to the Advanced Setup
page and WAN Settings to set up your
IGMP proxy. See page 19 for instructions.
PPP reconnect on WAN
access
Disabled by default. Enabling this feature
ensures that the PPP session is
automatically established when a packet is
ready to be transferred over the WAN.
PPP Half Bridge
Disabled by default. Enabling this feature
forces the DHCP server to duplicate the
X4’s WAN IP address to the local client
computer; thus, only one computer on the
LAN can access the Internet at a time.

System Administration
Using a computer attached to the X4 and a Web-based
browser such as Netscape Communicator or Internet Explorer,
you can administer your X4 unit and monitor your ADSL
connection.
Remember:
Remember If you are using an access point or a network hub,
you can administer your X4 from any of the computers that are
connected to the access point or hub.
3.1 Monitoring System Status
If you want to check the overall system status, click the System
Status icon at the top of the X4’s main interface page. (If you have
exited from the X4 and have forgotten how to establish

Linux TCP/IP Settings
The instructions for setting up boot-time DHCP vary dramatically
by distribution, so you may want to refer to your particular
version’s documentation.
Note: If you have other network cards installed, you will need to
pick distinct Ethernet identifiers for each (eth0, eth1, eth2,
etc.). If you select an identifier other than eth0 for your
ADSL modem, use that identifier throughout.
For RedHat
Edit or create /etc/sysconfig/network-scripts/ifcfg-eth0 so
that it contains the following three lines:
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
If you want to use a static IP address—for example, if you were
setting up a virtual server (page 23) or a DMZ (page 26)—you
would edit or create /etc/sysconfig/network-scripts/ifcfg-eth0
so that it contains the following lines:
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
Appendix C: Windows 95, Macintosh, and Linux Users
51
BROADCAST=172.16.31.255
IPADDR=172.16.16.55
NETMASK=255.25.240.0
NETWORK=172.16.16.0
Note: If your computer won’t always be on a network with
working DNS at boot-time, set ONBOOT=no. If you
don’t, RedHat 6.2 (and possibly other versions) might
hang. To activate the card by hand when you have
attached your computer to the network, at root, run the
command: /sbin/ifup eth0.
For SuSE
Edit the file /etc/rc.config; search for the variables
NETCONFIG, NETDEV_0, and IFCONFIG_0.
Set them as follows (see the instructions in rc.config):
NETCONFIG="_0"
NETDEV_0="eth0"
IFCONFIG_0="dhcpclient"
Reboot with this command: /sbin/shutdown -r now.
If you want to use a static IP address—for example, when setting
up a virtual server (page 23) or a DMZ (page 26)—consult the help
file or documentation that came with your operating system.
For Debian
Add this line to the file /etc/network/interfaces: iface eth0 inet
dhcp. Reboot with this command: /sbin/shutdown -r now.
If you want to use a static IP address—for example, when setting
up a virtual server (page 23) or a DMZ (page 26)—consult the help
file or documentation that came with your operating system.

Troubleshooting
Our Technical Support staff is ready to help you with any
questions you may have about your DSL modem or Internet
connection options. You may, however, find an easy solution to
your problem by referring to these troubleshooting tips. You
should also refer to the Frequently Asked Questions (FAQs) on
the CD (click on Support),
Support and visit our web site for the latest
tips: www.zoom.com.
PROBLEM: I installed the software and connected the
X4 modem to my phone line, but I cannot
connect to the Internet.
SOLUTION: Make sure you’ve securely connected the RJ-11
phone cord from the wall jack to the DSL modem
connector on the back of your computer.
SOLUTION: Make sure you’ve connected the RJ-11 phone cord
to a DSL line, not a standard telephone jack. You
cannot use a standard telephone jack for DSL service
unless that phone line has been enabled for DSL by
your phone service provider.
SOLUTION: If you are using the modem’s USB option, make sure
the unit’s USB cord is securely plugged into your
computer’s USB port.
SOLUTION: Make sure, if you are using phone filters, that they
are installed correctly (see page 13).
SOLUTION: Make sure you have typed your Username and
Password correctly.
SOLUTION: Contact your service provider to ensure that the DSL
connection is functioning properly.
Appendix D: Troubleshooting
53
PROBLEM: Why do I hear static or noise when I’m using
my telephone?
SOLUTION: If that phone does not have its own filter, you may
hear static or high-pitched noise if you make a phone
call while your ADSL modem is on. A filter also
prevents a phone from interfering with, or dropping,
your DSL connection.
PROBLEM: I accidentally unplugged the USB cable while
using my modem. This resulted in a general
protection fault (GPF) error message. What
should I do?
SOLUTION: You must plug the modem back in and restart your
computer to rectify this problem.
