If you are running v11.0 you can always attach an LTM iRule to the GTM listeners with something like this if you have a per-determined TLD like .local for your internal dns structure.
when DNS_RESPONSE {
if { ([DNS::question name] ends_with ".local") and !([IP::addr [IP::remote_addr] equals 10.0.0.0/8] or [IP::addr [IP::remote_addr] equals 172.16.0.0/12] or [IP::addr [IP::remote_addr] equals 192.168.0.0/16]) } {
DNS::drop
}
}
