Is there a way to block a specific query type on bind

772

I've been trying to find a way to block the WKS query type from our bind servers.

We have found that is is extensively used by tunneling software.

I tried using RPZ but i'm not sure on how to block a query type instead of domain.

However there seems to be no formal way of disabling a specific type.

Any ideas?

PS, i could use iptables but i'm unsure about the load on the systems
