User MAC Binding not worked

Hi Patrick Fleischer,

Thank you for reaching out to Sophos Community.

Which authentication method are you using?

Also, try changing 'Login restriction' in the user profile to Any node.

Hi Yash,

the registration restriction is already on all nodes. The login method  is user-based via Capative Portal.

Hi Patrick Fleischer MAC Binding option for SSL VPN client and Captive Portal is not supported. The KBA which you have used for reference covers the same information.

You may required to go for CAA ( Client authentication agent) for MAC binding.

Ok thanks for help @ all have a nice day.

I have still another question. Why does this not work without a client auth agent ? It used to work with the cyberoam. I read here in a post that this behaviur is a bug that was in the progress of being fixed. However this post is already over 5 Years old. How far is the fix ?
