CHAPTER 8
The VPN Transport Screens
8.1 Overview
This chapter describes the ADVANCED > VPN Transport screens, where you can configure
the WiMAX Modem to allow traffic from multiple users to pass through the WiMAX network
to the service provider’s router. Each user has his own personal connection to the service
provider, even though there is only a single WiMAX connection. This allows the service
provider to identify which user traffic comes from.
VPN stands for “Virtual Private Network”. There are many types of VPN; the type used by the
WiMAX Modem is known as Virtual Private LAN Service, or VPLS.
A Unlike some other types of VPN (such as IPSec VPNs) VPLS VPNs do not
use authentication or encryption to secure the data they carry.
The following figure shows two users (A and B), connecting to the WiMAX Modem (Z)
through a switch (S). Each user has his own connection over the WiMAX network to the
service provider’s router (R).
