Portal Authentication

As shown in Figure 1, user terminals' network access needs to be controlled to ensure network security. Only authenticated users are allowed to access network resources authorized by the administrator.

Figure 1 Typical application of Portal authentication

If the user only requires Portal authentication using a web browser, enable Portal authentication on the access device.

When an unauthenticated user accesses the Internet, the access device redirects the user to the Portal authentication website to start Portal authentication. If the authentication succeeds, the access device sets the interface connected to the user to the Up state and allows the user to access the network. If the authentication fails, the access device rejects the user's access request.
