Inconsistencies in Sangfor IAG Captive Portal for Apple Products

addimasqi Lv2Posted 12 Jul 2024 15:58

Hi all,
We are experiencing issues with our IAG running firmware IAG13.0.80. Our configuration requires users to log in to the Captive Portal to connect to the internet. We have configured the authentication server to use the Windows AD Domain. For most users with Windows products, the Captive Portal appears automatically. However, if the Captive Portal does not show up, they can simply open a browser (Chrome, Mozilla, Edge, etc.) and navigate to any website, and the Captive Portal (1.1.1.3) will appear. Alternatively, they can directly enter 1.1.1.3 into the browser address bar to access the Captive Portal.

However, users with Apple products often face difficulties accessing the Captive Portal. While it occasionally works normally, most of the time there are issues, and the Captive Portal fails to appear.

Did we make a mistake with the configuration?

Hi, as suggested below, try check your dns on the iphones that are able to solve the dns name of IAG captive portal. Please verify that the dns server provided on the iphones through wifi is correct and it's able to solve even dns names related to apple.

hi, have you set an ssl certificate on your captive portal? If not, try first to buy and set an ssl certificate on your IAG captive portal. After that, try connecting with your apple devices to capitve portal again.

Hi,

Some tips

SSL Certificate: Ensure the SSL certificate used by the Sangfor IAG captive portal is valid and properly configured. Apple devices are stringent about SSL/TLS connections, and any certificate errors can lead to inconsistencies.

Configure Captive Portal Settings: Double-check the configuration of your captive portal settings in Sangfor IAG. Ensure that settings such as session timeouts, authentication methods, and portal redirection are configured correctly and consistently.
