Installation Instructions

1.1 Important! Before you Begin

Before installing your X4 ADSL modem, you must have DSL service enabled on your telephone line. To do this, you need to sign up with a DSL service provider. They will arrange to have DSL enabled, and provide you with a User Name and Password (if required) and the Communications Settings necessary to log on to their network.

You will need your User Name and Password to complete the installation, so please make sure you have them at hand.

User Name _________________________

Password _________________________

The following table lists some of DSL broadband communications settings. This table is intended for reference only. Typically you should not need to enter this information; it should be automatically supplied if needed as part of your service provider’s installation procedure.

• CD-ROM, including installation software

• Warranty and Customer Support information (on CD-ROM)

• Phone filter(s) (certain models only).

If anything is missing or damaged, please contact your supplier.

You Will Also Need

•

A Macintosh, Linux, or Windows 98/98SE/2000/Me/XP computer equipped with a Network Interface Card (NIC) or a Windows 98/98SE/2000/Me/XP computer equipped with a USB port.

•

A telephone wall jack to plug the X4 unit into. The associated phone line must be DSL enabled.

1.3 Quick Start Instructions

Your computer should be on. Windows users: You can connect your X4 unit to your computer’s

Ethernet or USB port. Macintosh and Linux users: You must select the Ethernet option. Depending on your operating system and preference, follow the appropriate instructions below.

Note:

6 X4 ADSL Modem User’s Manual

Windows users have the option of using both the X4’s Ethernet jack and its USB jack. By connecting two computers individually to your X4 unit—one using the Ethernet jack and the other using the USB jack—it is possible to share Internet access.

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 jack if you like. Plugging a device into this jack is optional, not required. plug your telephone into the filter’s X4’s

2.4 NAT Firewa ll

The X4’s built-in NAT (Network Address Translation) firewall provides a good level of protection from unauthorized access. NAT keeps private a network’s internal IP addresses and presents to the Internet one public IP address. With NAT, only one LAN user can use the public IP address. NAT’s more robust counterpart, NAPT (Network Address Port Translation), allows specified LAN users to share the one public IP address. Both NAPT and NAT are transparent to end users.

Your X4’s NAT firewall is enabled by default; the default setting is

dynamic NAPT

anyone can use the public IP address (that is, the modem’s WAN IP address). You shouldn’t need to change this setting. However, if your service provider instructs you to disable it (or change it), go to the

2.5 Virtual Server (Port Forwarding)

If you need to allow outside users access to a computer (or computers) on your LAN—for example, if you are hosting an Internet game—you have to open up an X4’s inbound port. 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 a port is not opened, the X4 will block and discard the packets.

One way to open up a port is to implement a virtual server (sometimes referred to as port forwarding). Note that one virtual server entry opens up one port. It is possible to open multiple ports (for a maximum of 20), but you have to configure a virtual server entry for each one individually. In other cases, you might want to have all ports open to one computer and for this you need to set up a Demilitarized Zone (DMZ); see page 25 for instructions on configuring a DMZ.

An example will help to illustrate how to set up a virtual server. In our example, we will demonstrate how to use your computer as an FTP server.

Tip:

We recommend that you visit the ports list section of Practically Networked’s web site if you need help:

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!

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

2.9 Route Table

The X4 includes a routing table function for users who want to set up an additional network (or networks) residing on a different subnet than the X4. Without a route table, any computer residing on an additional subnet would be invisible to the modem. The route table acts as a map for the modem, so that it directs traffic to the correct subnet location.

To access the route table function, click the the top of the route table entries. (These entries are automatically displayed once you connect the X4.) Under address of the X4’s LAN interface (for example, 10.0.0.0), the IP address of the local loopback test (127.0.0.1), and the IP address of the WAN interface (for example, 192.168.1.1). Under you will see the corresponding subnet masks for these three Destinations. Under Gateway IP addresses.
