Configure RPZ to walled-garden query to forbidden domain

Hi all,

 

I've implement "transparent DNS cache" and RPZ to walled-garden if user query to forbidden domain (example pron domain). We use bind server as zone master (list of forbidden domain) and f5 as secondary zone.

 

The problem, if we want to walled-garden xxx.com and we need add that two domain at list of forbidden domain. is any solution so we only list one domain (example xxx.com) and DNS cache can walled-garden query to xxx.com and domain?

 

Kind Regards,
