  • 1.  Captive Portal Appending Certificate CN to Redirect URL

    Posted Sep 19, 2024 12:16 PM

    I'm trying to build a guest Wi-Fi network using a 3rd-party captive portal. The network is functional up until I submit the login on the portal page, it then tries to redirect back to the gateway IP which we are appending to the redirect URL. Instead of the IP address, we would like to redirect back to the CN of the captive portal certificate. This was possible in AOS 8 - where it was a text box allowing to enter the FQDN. In AOS 10, now it's a dropdown menu that only allows the selection of a VLAN interface. 

    In the CLI of the gateway, you can still enter a FQDN, I tested this by enabling DR mode and the commands were accepted successfully. Is there any way to get this to happen otherwise? Is it possible to manually append this to the login page URL? 

    Thanks.

    That's probably a question you can best ask through your local Aruba SE. I don't know the answer, and it's 'future looking' so can't really be answered in public.

    Thanks Herman, we are working with our local SE and TAC, but ultimately this just seems to be a platform limitation now that the configuration for WLANs take place on the AP side and no longer on the Gateway. We're continuing our troubleshooting with HPE/Aruba and our captive portal vendor to try and develop a solution. This is only a problem for Tunnel mode WLANs, Bridge mode this is not an issue, but is not a feasible topology for us.
