About a 1000 users are using my dns name server using public IPs. I need to restrict dns (udp) requests to not more than 3 requests per second from each client's IP. Is there a way which we can apply this restriction using the configuration files of Bind or IPFW or anything for the matter. - -- With best regards and good wishes, Yours sincerely, Tek Bahadur Limbu (TAG/TDG Group) Jwl Systems Department Worldlink Communications Pvt.
