Nomadix AG5800 - Portal Page Redirect; RADIUS-Driven Auto Configuration

ACCESS GATEWAY
Introduction 21
Running as a continuous background client program on a computer, NTP sends periodic time
requests to servers, obtaining server time stamps and using them to adjust the client's clock.
Portal Page Redirect
The NSE contains a comprehensive HTTP page redirection logic that allows for a page redirect
before (Portal Page Redirect) and/or after the authentication process (Home Page Redirect).
As part of the Portal Page Redirect feature, the NSE can send a defined set of parameters to the
portal page redirection logic that allows an External Web Server to perform a redirection based
on:
 Access Gateway ID and IP Address
 Origin Server
 Port Location
 Subscriber MAC address
 Externally hosted RADIUS login failure page
This means that the network administrator can now perform location-specific service branding
(for example, an airport lounge) from a centralized Web server.

RADIUS-driven Auto Configuration
Nomadix’ unique RADIUS-driven Auto Configuration functionality utilizes the existing
infrastructure of a mobile operator to provide an effortless and rapid method for configuring
devices for fast network roll-outs. Once configured, this methodology can also be effectively
used to centrally manage configuration profiles for all Nomadix devices in the public access
network.
Two subsequent events drive the automatic configuration of Nomadix devices:
1. A flow of RADIUS Authentication Request and Reply messages between the Nomadix
gateway and the centralized RADIUS server that specifies the location of the meta
configuration file (containing a listing of the individual configuration files and their
download frequency status) are downloaded from an FTP server into the flash of the
Nomadix device.
2. Defines the automated login into the centralized FTP server and the actual download
process into the flash.
Optionally, the RADIUS authentication process and FTP download can be secured by sending
the traffic through a peer-to-peer IPSec tunnel established by the Nomadix gateway and
