The VPN Transport Screens
9.1 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.
Note: 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).

Note: The services available may vary, depending upon the service provider.
