CHAPTER 1
Introduction
1.1 Overview
The UAG is a comprehensive service gateway. The UAG combines an IEEE 802.11n wireless access
point, router, 4-port switch and service gateway in one box. If you have a "statement printer", such
as SP350E, you can connect it directly to the UAG, allowing you to easily print subscriber
statements. The UAG is ideal for offices, coffee shops, libraries, hotels and airport terminals
catering to subscribers that seek Internet access. You should have an Internet account already set
up and have been given usernames, passwords etc. required for Internet access.
You can use web authentication to allow guests to access the network only after they authenticate
with the UAG through a specifically designated login web page. You can also forward the
authenticated client's e-mail messages to a specific SMTP server.
The UAG also provides bandwidth management, NAT, port forwarding, policy routing, DHCP server
and many other powerful features. The UAG’s security features include firewall and certificates.
The UAG lets you set up multiple networks for your company. The UAG also provides two separate
LAN networks. You can set ports to be part of the LAN1 or LAN2. Alternatively, you can deploy the
UAG as a transparent firewall in an existing network with minimal configuration.
1.2 Default Zones, Interfaces, and Ports
The default configurations for zones, interfaces, and ports are as follows. References to interfaces
may be generic rather than the specific name used in your model. For example, this guide may use
“the WAN interface” rather than “P1”.

Command-Line Interface (CLI)
The CLI allows you to use text-based commands to configure the UAG. Access it using remote
management (for example, SSH or Telnet) or via the physical or Web Configurator console port.
See the Command Reference Guide for CLI details. The default settings for the console port are:
1.4 Web Configurator
In order to use the Web Configurator, you must:
• Use one of the following web browser versions or later: Internet Explorer 6.0, Firefox 8.0,
Chrome 14.0, Safari 4.0
• Allow pop-up windows (blocked by default in Windows XP Service Pack 2)
• Enable JavaScripts, Java permissions, and cookies
The recommended screen resolution is 1024 x 768 pixels.
1.4.1 Web Configurator Access
1Make sure your UAG hardware is properly connected. See the Quick Start Guide.
2In your browser go to http://172.16.0.1 or http://172.17.0.1. By default, the UAG automatically
routes this request to its HTTPS server, and it is recommended to keep this setting. The Login
screen appears.
3Type the user name (default: “admin”) and password (default: “1234”).
