Mettle SE has Captive Portal feature used for HTTP authentication with a web browser. Once the Captive Portal has been enabled on a local network the clients on the network will be re-directed an HTTP authentication web page before they can start browsing or check their mails.

To enable captive portal on your Mettle SE:

  1. Go to Security >> Captive Portal
  2. Check the check box which says "Enable Captive Portal"
  3. Choose the interface captive portal is to be run on. Usually this is your local network.
  4. Enter the maximum number of concurrent connections that is to be allowed
  5. Enter the idle time out in minutes. Clients will be disconnected after the time you specify.
  6. Enter the hard time out in seconds. Clients (active clients also) will be disconnected after the time you specify exceeds.
  7. Check the box to enable logout pop up window if required.
  8. Redirection URL - All clients after successful login would be redirected to the URL entered here.
  9. Concurrent logins - If enabled only most recent login per user name will be active. Subsequent logins will cause machines previously logged in with the same user name to be disconnected.
  10. MAC filtering - If disabled, no attempts will be made to ensure that the MAC address of clients stays the same while they're logged in. This is required when the MAC address of the client cannot be determined (usually because there are routers between Mettle SE and the clients). If this is enabled, RADIUS MAC authentication cannot be used.
  11. Authentication - Chose 'No Authentication', 'Local user manager' or 'RADIUS'. If RADIUS is chosen enter the RADIUS Server details below. If 'Local User Manager' is chosen manage users in the "Users" tab.
  12. Enable HTTPS login - If enabled the user information would be transmitted via an HTTPS connection.
  13. Enter the details for the HTTPS servers in the fields below.
  14. Click on 'Save' after you have finished.
