I know this is kind of a crazy idea but how about making cleaning up all these infected machines the priority as a solution instead of defending your dns from your infected clients. They not only affect you, they affect the rest of us so why should we give you a solution to your problem when you don't appear to care about causing problems for the rest of us?
Has anyone figured out a remote but lawful way to repair zombie machines? Pete

Unluckly, a lot of clients start to bomb my DNSs at a certain hour, so I have a distributed tentative of denial of service. I can't blacklist them on my DNSs, because the infected clients are too much. For this reason, I would like that a DNS could response maximum to 10 queries per second given by every single Ip address. Anybody knows a solution, just using iptables/netfilter/kernel tuning/BIND tuning, without using any hardware traffic shaper? Thanks Best Regards Luke
