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.

Introduction 4
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 provides an RS232 serial
port for connecting to a Property Management System (PMS), 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.
•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
Introduction 5
Billing Enablement
The Access Gateway supports billing plans using PayPal, 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:

ACCESS GATEWAY
Introduction 6
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.
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).

Access Control
For IP-based access control, the NSE incorporates a master access control list that checks the source (IP
address) of administrator logins. A login is permitted only if a match is made with the master list contained
within the NSE. If a match is not made, the login is denied, even if a correct login name and password are
supplied.
The access control list supports up to 50 (fifty) entries in the form of a specific IP addressor range of IP
addresses.
The NSE also offers access control based on the interface being used. This feature allows administrators to
block access from Telnet, Web Management, and FTP sources.
Administration can now be performed after unblocking the interfaces for the Subscriber side of the NSE. The
Administrative ports are configurable as well. See Establishing Secure Administration {Access Control},
page 75.
Bandwidth Management
The NSE optimizes bandwidth by limiting bandwidth usage symmetrically or asymmetrically on a per device
(MAC address / User) basis, and manages the WAN Link traffic to provide complete bandwidth management
over the entire network. You can ensure that every user has a quality experience by placing a bandwidth
ceiling on each device accessing the network, so every user gets a fair share of the available bandwidth.
With the Nomadix ICC feature enabled, subscribers can increase or decrease their own bandwidth and pricing
plans for their service dynamically.
You can set default maximum up and down bandwidths for subscribers who do
not have a specified bandwidth setting. See Setting Up Bandwidth
Management {Bandwidth Management} on page 80.
