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".
