  • Hi,

     

    You can try to write an irule to do a reverse lookup based on the client ip address. Otherwise, if you have APM module and Client Side Endpoint Checks, you can retrieve the computer name and use it within an irule using one of the available ASM event.

     

    Last thing, you can also do machine certificate based authentication, the machine certificate must match the computer name. Thus, you collect this information within an irule and use an ASM event to check it and block it if required.

     

    Regards
