ZyXEL Communications ISG50 ユーザーズマニュアル

ISG50 User’s Guide

Use authentication policies to control who can access the network. You can authenticate users 
(require them to log in). 

Use the Configuration > Auth. Policy screens (

) to create and manage 

authentication policies.

Authentication policies are applied based on a traffic flow’s source and destination IP addresses. If 
VPN traffic matches an authentication policy’s  source and destination IP addresses, the user must 
pass authentication. 

Instead of making users for which user-aware policies have been configured go to the ISG50 Login 
screen manually, you can configure the ISG50 to display the Login screen automatically whenever 
it routes HTTP traffic for anyone who has not logged in yet. 

Note: This works with HTTP traffic only. The ISG50 does display the Login screen when 

users attempt to send other kinds of traffic.

The ISG50 does not automatically route the request that prompted the login, however, so users 
have to make this request again.

See 

 for an example of how to use authentication policies.

The Authentication Policy screen displays the authentication policies you have configured on the 
ISG50.
