I'm a big believer in using ACLs to intelligently preclude reflection/amplification abuse, but wholesale filtering of all UDP takes matters too far, IMHO.
I also think that restricting your users by default to your own recursive DNS servers, plus a couple of well-known, well-run public recursive services, is a good idea - as long as you allow your users to opt out. This has nothing to do with DDoS, but with other types of issues. ----------------------------------------------------------------------- Roland Dobbins <rdobbins () arbor net> // <http://www.arbornetworks.com> Luck is the residue of opportunity and design. -- John Milton
