10 Introduction
Welcome to the AG 5000
The AG 5000 is a freestanding, fully featured network appliance that enables Public
access service providers to offer broadband Internet connectivity to their customers.
The AG 5000 handles universal mobile connectivity, advanced security, policy-based
traffic shaping, and service placement supporting up to 2,000 users simultaneously in
a broadband environment. The AG 5000 also offers a unique set of security and
connectivity features for deploying wireless 802.11 networks.
The AG 5000 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, including the AG 5000, are powered by our
patented and patent-pending suite of embedded software, called the Nomadix Service
Engine™ (NSE). The AG 5000 employs our NSE core software package with the
option to purchase additional modules to expand the product’s functionality.
This User’s Guide covers all features and functionality provided with the NSE core
package, as well as the 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:

AG 5000
Introduction 11
Key Features and Benefits
The AG 5000 is a 1U high, free-standing or rack-mountable Access Gateway that
employs three fast Ethernet ports to interface with the router (one for network side)
and the aggregation equipment (two for subscriber side) 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 AG 5000 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.
The AG 5000 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.
Platform Reliability
The AG 5000 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 AG 5000’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

12 Introduction
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.
Billing Enablement
The AG 5000 supports billing plans using credit cards, scratch cards, 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.

AG 5000
Introduction 13
Access Control and Authentication
The AG 5000 ensures that all traffic to the Internet is blocked until authentication has
been completed, creating an additional level of security in the network. Also, 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.
Security
The patent-pending 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 AG 5000 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 AG 5000 (or any other 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.
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
address or 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.
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 Information and Control Console (ICC) feature enabled,
subscribers can increase or decrease their own bandwidth dynamically (by the minute,
or on an hourly, daily, weekly, or monthly basis), and also adjust the pricing plan for
their service (see graphic).

16 Introduction
Bridge Mode
This feature allows complete and unconditional access to devices. When Bridge
Mode is enabled, your NSE-powered product is effectively transparent to the network
in which it is located.
The NSE forwards any and all packets (except those addressed to the NSE network
interface). The packets are unmodified and can be forwarded in both directions. The
Bridge Mode function is a very useful feature when troubleshooting your entire
network as it allows administrators to effectively “remove” your product from the
network without physically disconnecting the unit.
Command Line Interface
The Command Line Interface (CLI) is a character-based user interface that can be
accessed remotely or via a direct cable connection. Until your Nomadix product is up
and running on the network, the CLI is the Network Administrator’s window to the
system. Software upgrades can only be performed from the CLI.

Dynamic Address Translation™
Dynamic Address Translation (DAT) enables transparent broadband network
connectivity, covering all types of IP configurations (static IP, DHCP, DNS),
regardless of the platform or the operating system used—ensuring that everyone gets
access to the network without the need for changes to their computer’s configuration
settings or client-side software. The NSE supports both PPTP and IPSec VPNs in a
manner that is transparent to the user and that provides a more secure standard
connection. See also, “Transparent Connectivity” on page 12.
Dynamic Transparent Proxy
The NSE directs all HTTP and HTTPS proxy requests through an internal proxy
which is transparent to subscribers (no need for users to perform any reconfiguration
tasks). Uniquely, the NSE also supports clients that dynamically change their browser
status from non-proxy to proxy, or vice versa. In addition, the NSE supports proxy
ports 80, 800-900, 911 and 990 as well as all unassigned ports (for example, ports
above 1024), thus ensuring far fewer proxy related support calls than competitive
products.
