You should also do it on customer-facing ports not allowing anything to come in, but that would be best approached once Mikrotik and the per interface setting for unicast reverse path filtering. You would then said customer facing interfaces to strict and all other interfaces to loose. They accepted the feature request, just haven't implemented it yet. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Mike Hammett" <wispawirel...@ics-il.net> To: "WISPA General List" <wireless@wispa.org> Sent: Friday, October 21, 2016 11:23:24 AM Subject: [WISPA] Another Large DDoS, Stop Being a Dick There's another large DDoS going on now. Go to this page to see if you can be used for UDP amplification (or other spoofing) attacks: https://www.caida.org/projects/spoofer/ Go to these pages for more longer term bad behavior monitoring: https://www.shadowserver.org/wiki/ https://radar.qrator.net/ Maybe we need to start a database of ASNs WISPs are using and start naming and shaming them when they have bad actors on their network. This is serious, people. Take it seriously. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP _______________________________________________ Wireless mailing list Wireless@wispa.org http://lists.wispa.org/mailman/listinfo/wireless _______________________________________________ Wireless mailing list Wireless@wispa.org http://lists.wispa.org/mailman/listinfo/wireless
