2Introduction
Welcome to the AG 5500
The AG 5500 is a freestanding, fully featured network appliance that enables Public access
service providers to offer broadband Internet connectivity to their customers.
The AG 5500 handles universal mobile connectivity, advanced security, policy-based traffic
shaping, and service placement supporting up to 200 users simultaneously in a broadband
environment. The AG 5500 also offers a unique set of security and connectivity features for
deploying wireless 802.11 networks.
The AG 5500 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 5500, are powered by our patented
and patent-pending suite of embedded software, called the Nomadix Service Engine™ (NSE).
The AG 5500 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:
See also:

Your product license may not support this feature.

AG 5500
Introduction 3
Key Features and Benefits
The AG 5500 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 5500 enables a wide variety of network deployment options for different venue types.
For example:
zAllows for flexible WAN Connectivity (T1/E1, Cable, xDSL, and ISDN).
zSupports 802.11a/b/g and hybrid networks utilizing wired Ethernet.
zSupports key requirements needed to be compliant with the Wi-Fi ZONE™ program.
zLets you segment your existing network into public and private sections using
VLANs, then leverage your existing network investment to create new revenue
streams.
zEnables you to provide Wi-Fi access as a billable service or as an amenity to augment
the main line of business for your venue.
zThe AG 5500 contains an advanced XML interface for accepting and processing
XML commands, allowing the implementation of a variety of service plans and
offerings.
zOffers 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 5500 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 5500’s Portal Page feature intercepts users’ 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.
zAllows the provider to present their customers with local services or have the user
sign up for service at zero expense.
zOffers both pre and post authentication redirects of the user’s browser, providing
maximum flexibility in service branding.

4Introduction
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 5500 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.

Introduction 5
Access Control and Authentication
The AG 5500 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. MAC-based authentication is also available.
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 5500 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 5500 (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.
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}.

8Introduction
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).
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.
