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).
