There aren't many filters available that can tell the difference between an OPCODE=QUERY DNS message and an OPCODE=UPDATE message. Also, I don't think pointing a client at a forwarder that is configured not to forward updates is going to help, given that the Microsoft and ISC dynamic update routines send updates directly to the authoritative name servers for the enclosing zone, not to the resolver's default name server. cricket
