CHAPTER 20
Web Authentication
20.1 Web Auth Overview
Web authentication can intercept network traffic, according to the authentication policies, until the
user authenticates his or her connection, usually through a specifically designated login web page.
This means all web page requests can initially be redirected to a special web page that requires
users to authenticate their sessions. Once authentication is successful, they can then connect to the
rest of the network or Internet.
As soon as a user attempt to open a web page, the ZyWALL/USG reroutes his/her browser to a web
portal page that prompts him/her to log in.
Figure 306 Web Authentication Example
The web authentication page only appears once per authentication session. Unless a user session
times out or he/she closes the connection, he or she generally will not see it again during the same
session.
