Configuring support of Web proxy for portal authentication

About the support of Web proxy for portal authentication

To allow HTTP requests proxied by a Web proxy server to trigger portal authentication, specify the port number of the Web proxy server on the device. If a Web proxy server port is not specified on the device, HTTP requests proxied by the Web proxy server are dropped, and portal authentication cannot be triggered.

Restrictions and guidelines

If a user's browser uses the Web Proxy Auto-Discovery (WPAD) protocol to discover Web proxy servers, you must perform the following tasks on the device:

If portal users enable Web proxy in their browsers, the users must add the IP address of the portal authentication server as a proxy exception in their browsers. Thus, HTTP packets that the users send to the portal authentication server will not be sent to Web proxy servers.

You cannot specify Web proxy server port 443 on the device.

You can execute this command multiple times to specify multiple port numbers of Web proxy servers.
