WAN/Internet

5.1 Overview

This chapter discusses the SBG's WAN/Internet screens. Use these screens to configure your SBG for
Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It
connects your private networks, such as a LAN (Local Area Network) and other networks, so that a
computer in one location can communicate with computers in other locations.

3G (third generation)/4G (fourth generation) standards are used for the sending and receiving of voice,
video, and data in a mobile environment.
You can attach a 3G/4G wireless adapter to the USB port and set the SBG to use this 3G connection as
your WAN or a backup when the wired WAN connection fails.
