ACCESS GATEWAY
Introduction 3
Welcome to the Access Gateway
The Access Gateway is a freestanding, fully featured network appliance that enables public
access service providers to offer broadband Internet connectivity to their customers.
The Access Gateway handles transparent connectivity, advanced security, policy-based traffic
shaping, and service placement supporting thousands of users simultaneously in a broadband
environment. The Access Gateway also offers a unique set of security and connectivity
features for deploying metro wireless 802.11 networks, including Mesh and WiMAX
technologies.
The Access Gateway yields a complete solution to a set of complex issues in the Enterprise,
Public-LAN, and Residential segments.
Product Configuration and Licensing
All Nomadix Access Gateway products are powered by our patented and patent-pending suite
of embedded software, called the Nomadix Service Engine™ (NSE). The Access Gateway
employs our NSE core software package and comes pre-packaged with the option to purchase
additional modules to expand the product’s functionality.
This User Guide covers all features and functionality provided with the NSE core package, as
well as additional optional modules. Your product license must support the optional NSE
modules if you want to take advantage of the expanded functionality. The following note will
preface procedures that directly relate to optional modules.

ACCESS GATEWAY
4 Introduction
Key Features and Benefits
The Access Gateway is a 1U high, free-standing or rack-mountable device that provides
Ethernet ports to interface with the router and the aggregation equipment within the network. It
also incorporates an RS232 serial port for connecting to a Property Management System
(PMS) and for system management and administration, while maintaining one billing
relationship with their chosen provider.
The Access Gateway enables a wide variety of network deployment options for different venue
types. For example:
Allows for flexible WAN Connectivity (T1/E1, Cable, xDSL, and ISDN).
Supports 802.11a/b/g and hybrid networks utilizing wired Ethernet.
Supports key requirements needed to be compliant with the Wi-Fi ZONE™ program.
Allows you to segment your existing network into public and private sections using
VLANs, then leverage your existing network investment to create new revenue
streams.
Enables you to provide Wi-Fi access as a billable service or as an amenity to augment
the main line of business for your venue.
Contains an advanced XML interface for accepting and processing XML commands,
allowing the implementation of a variety of service plans and offerings.
Offers three user-friendly ways of remote management—through a Web interface,
SNMP MIBs, and Telnet interfaces—allowing for scalable, large public access
deployments.
Provides capabilities for load balancing and fail-over management across multiple
ISPs.
Platform Reliability
The Access Gateway is designed as a network appliance, providing maximum uptime and
reliability unlike competitive offerings that use a server-based platform.
Local Content and Services
The Access Gateway’s Portal Page feature intercepts the user’s browser settings and directs
them to a designated Web site to securely sign up for service or log in if they have a pre-
existing account.
Allows the provider to present their customers with local services or have the user
sign up for service at zero expense.

ACCESS GATEWAY
Introduction 5
Offers both pre and post authentication redirects of the user’s browser, providing
maximum flexibility in service branding.
Transparent Connectivity
Resolving configuration conflicts is difficult and time consuming for network users who are
constantly on the move, and costly to the solution provider. In fact, most users are reluctant to
make changes to their computer’s network settings and won’t even bother. This fact alone has
prevented the widespread deployment of broadband network services.
Our patented Dynamic Address Translation™ (DAT) functionality offers a true “plug and
play” solution by enabling a seamless and transparent experience and the tools to acquire new
customers on-site.
DAT greatly reduces provisioning and technical support costs and enables providers to deliver
an easy to use, customer-friendly service.

ACCESS GATEWAY
6 Introduction
Billing Enablement
The Access Gateway supports billing plans using credit cards, scratch cards, or monthly
subscriptions, or direct billing to a hotel’s Property Management System (PMS) and can base
the billable event on a number of different parameters such as time, volume, IP address type, or
bandwidth.
Access Control and Authentication
The Access Gateway ensures that all traffic to the Internet is blocked until authentication has
been completed, creating an additional level of security in the network. Also, the Access
Gateway allows service providers to create their own unique “walled garden,” enabling users
to access only certain predetermined Web sites before they have been authenticated.
Nomadix simultaneously supports the secure browser-based Universal Access Method (UAM),
IEEE 802.1x, and Smart Clients for companies such as Adjungo Networks, Boingo Wireless,
GRIC and iPass. MAC-based authentication is also available.
Security
The patented iNAT™ (Intelligent Network Address Translation) feature creates an intelligent
mapping of IP Addresses and their associated VPN tunnels—by far the most reliable multi-
session VPN passthrough to be tested against diverse VPN termination servers from companies
such as Cisco, Checkpoint, Nortel and Microsoft. Nomadix’ iNAT feature allows multiple
tunnels to be established to the same VPN server, creating a seamless connection for all users
on the network.
The Access Gateway provides fine-grain management of DoS (Denial of Service) attacks
through its Session Rate Limiting (SRL) feature, and MAC filtering for improved network
reliability.
5-Step Service Branding
A network enabled with the Nomadix Access Gateway offers a 5-Step service branding
methodology for service providers and their partners, comprising:
1. Initial Flash Page branding.
2. Initial Portal Page Redirect (Pre-Authentication). Typically, this is used to redirect the user
to a venue-specific Welcome and Login page.
3. Home Page Redirect (Post-Authentication). This redirect page can be tailored to the
individual user (as part of the RADIUS Reply message, the URL is received by the NSE)
or set to re-display itself at freely configurable intervals.

ACCESS GATEWAY
Introduction 7
4. The Information and Control Console (ICC) contains multiple opportunities for an
operator to display its branding or the branding of partners during the user’s session. As an
alternative to the ICC, a simple pop-up window provides the opportunity to display a
single logo.
5. The “Goodbye” page is a post-session page that can be defined either as a RADIUS VSA
or be driven by the Internal Web Server (IWS) in the NSE. Using the IWS option means
that this functionality is also available for other post-paid billing mechanisms (for
example, post-paid PMS).
