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 4.
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.
End User Licensee Count
The NSE supports a range of simultaneous user counts depending on the Nomadix Access Gateway you
choose. In addition, depending on your platform, various user count upgrades are available for each of our
NSE-powered products that allow you to increase the simultaneous user count.
External Web Server Mode
The External Web Server (EWS) interface is for customers who want to develop and use their own content. It
allows you to create a “richer” environment than is possible with your product’s embedded Internal Web
Server.
The advantages of using an External Web Server are:

Manage frequently changing content from one location.
 Serve different pages depending on site, sub-location (for example, VLAN), and user.

Take advantage of the comprehensive Nomadix XML API to implement more complex billing plans.

Recycle existing Web page content for the centrally hosted portal page.
If you choose to use the EWS interface, Nomadix Technical Support can provide you with sample scripts. See
