CHAPTER 21 Authentication Server Screens 21.1 Overview This chapter discusses how to configure the ZyWALL's authentication server feature. 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. 21.1.1 What You Can Do in the Authentication Server Screens • Use the Local User Database Screen (Section 21.2 on page 428) to configure your ZyWALL's list of local user profiles. • Use the RADIUS Screen (Section 21.3 on page 430) to configure external RADIUS server settings. 21.1.2 What You Need To Know About Authentication Server 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. RADIUS The ZyWALL can use an external RADIUS server to authenticate an unlimited number of users. RADIUS is based on a client-server model that supports authentication and accounting, where access point is the client and the server is the RADIUS server. • Authentication Determines the identity of the users. • Accounting Keeps track of the client's network activity. RADIUS user is a simple package exchange in which your ZyWALL acts as a message relay between the wireless station and the network RADIUS server. Finding Out More Refer to Section 12.4 on page 244 for more information about RADIUS. ZyWALL 5/35/70 Series User's Guide 427
