Overview

The X4 is an ADSL modem and a gateway/router all contained in one device.

The ADSL modem gives you a connection to the Internet through your Internet service provider.

The gateway/router provides an interface between the Internet and your own local network. It also includes an advanced firewall, which allows you to control Internet access from your local network, and which protects your local network from unwanted Internet traffic.

The X4 modem is also enabled for Universal Plug and Play (UPnP™). This means that if you plug other devices with UPnP capabilities into your computer or network (for example, a gaming application, router, or stand-alone firewall) they will automatically detect the X4 and make the needed configurations for them to work together.

This User Guide contains installation instructions for Macintosh and Linux computers, which can also be used for manually installing the X4 on a Windows computer. There is also information about the X4’s advanced setup options. Though most users will not need to use the advanced setup options, there are cases in which these advanced settings are necessary (for example, if you have a static IP address).
