Authentication Server
This chapter discusses how to configure the ZyWALL’s authentication server feature.
21.1 Authentication Server Overview
A ZyWALL set to be a VPN extended authentication server can use either the local user
database internal to the ZyWALL or an external RADIUS server for an unlimited number of
users. The ZyWALL uses the same local user database for VPN extended authentication and
wireless LAN security. See
Section 9.14 on page 185 for more information about RADIUS.
21.1.1 Local User Database
By storing user profiles locally on the ZyWALL, your ZyWALL is able to authenticate users
without interacting with a network RADIUS server. However, there is a limit on the number of
users you may authenticate in this way.
21.1.2 RADIUS
The ZyWALL can use an external RADIUS server to authenticate an unlimited number of
users.
21.2 Local User Database
Click SECURITY and then AUTH SERVER to open the Local User Database screen. Use
this screen to change your ZyWALL’s local user list.
