VPN Transport
11.1 Overview
This chapter describes the Network > VPN Transport screens.
The ZyXEL Device ’ s VPN Transport feature allows 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.
The following figure shows two users ( A and B ), connecting to the ZyXEL Device ( Z )
through a switch ( S ). Each user has his own connection over the WiMAX network to the
service provider ’ s router (

).

The services available may vary, depending upon the service provider.
VPN stands for “ Virtual Private Network ” . There are many types of VPN; the type used by the
ZyXEL Device is known as Virtual Private LAN Service, or VPLS.
Unlike some other types of VPN (such as IPSec VPNs) VPLS VPNs do not
use authentication or encryption to secure the data they carry.
