Bind Wide IP to a DNS Listener

Hi! We have two F5 DNS, each one with two Listeners configured publishing DNS to Internet and to the Intranet.

 

We have two Sites, and we want to configure some DNS entries with Global Availability to Internet, and others entries to the Intranet.

 

I'm seeing a Wide IP cant't be bound to a DNS Listener, so how can I configure it to only accept DNS request from Internet or from the Intranet? I think an iRule is needed, is there any simple way to do it?

 

Thanks!
