Hi all,

We have a big  problem  all 3 of our dns servers are under Amplification attack
As soon as we start nsd we send out 50 mbit to the internet.
Any ideas how can stop this .

We run NSD version 4.1.2 (most recent in ondrej nlnetlabs ppa)

My nsd.conf can be found here: http://pastebin.com/kAHcRiVf

suggestions are greatly appreciated
