5. Go to the Wireless > Wireless Settings page and enable the Portal option for the
specific SSID. Then the portal authentication feature will take effect on this SSID.
Specify the value of authentication timeout.
A client's authentication will expire after the authentication timeout and
the client needs to log in to the authentication page again to access the
network.
Options include 1 Hour, 8 Hours, 24 Hours, 7 Days, and Custom. With
Custom selected, you can customize the time in days, hours, and minutes.
With this function configured, the newly authenticated client will be
redirected to the specific URL.
With Redirect enabled, you also need to enter the URL in this field. The
newly authenticated client will be redirected to this URL.
Configure the authentication page. There are two options: Local Web
Portal and External Web Portal.
· Local Web Portal
Enter the title and term of use in the two boxes. The EAP uses its built-
in web server to provide this authentication page for clients. To pass
the authentication, clients need to provide the correct username and
password in the Username and Password fields, check the box of I accept
the Term of Use and click the Login button.
· External Web Portal
With External Web Portal configured, the authentication page will be
provided by the web portal server built on the network. To configure
External Web Portal, you need to complete the following configurations:
1. Build an external web portal server on your network and make sure that
it is reachable by the EAP.
2. On this configuration page, enter the URL of the authentication page
provided by the external portal server.
3. Add the external web portal server to the Free Authentication Policy
list. In this way, clients can access the web portal server before
authenticated. For details about how to configure Free Authentication
Policy, refer to Configure Free Authentication Policy
