RADIUS SSO Dropping Authentication

I have a problem with the RADIUS SSO where by when laptops and devices connect to the wireless it authenticates against the Windows NPS server which then forwards the accounting packets to the Sophos XG.

This works and users are able to connect and get the appropriate web filter level. However, as they move around site and jump from Access Point to Access Point they will randomly lose the Sophos Authentication and therefore lose internet.

I have check on the NPS server and can see in the Accounting Requests packets that it is receiving both a username and IP address.

I  am still however getting these errors in the access_server.log on the Sophos XG.

  • Hello there,

    Thank you for the follow-up.

    I was suspecting the Framed-IP but you mentioned it’s being seen and sent.

    I would recommend you to open a Case ID, or if you already have one, share it with me.

    Please provide the logs of access_server in debug mode:

    # service access_server:debug -ds nosync

    The wireless.log and a pcap of the corresponding traffic.

    Regards,
