Victor,

NAT translate the DNS A and PTR lookups

I haven’t seen a command that will disable just the DNS translation, but you might be able to achieve your goals by explicitly denying the DNS server address in your NAT access list.

I think there is a command that will disable DNS translation, that will be entered in global configuration mode ( no ip domain-lookup)
