What if one of them decided that our wifi was "rogue" and started trying to stamp it out? It happens daily. We have 22 offices around the world, each in downtown towers. We use Cisco WLCs, and those controllers see constant deauth frames coming from people above us, below us, and from the four sides around us. It is a real battle. The only thing to do is use lots of APs in the office so as to keep the power levels down. In a couple of cases our office managers personally visited the offices of people above, below, and across from us and discussed the problem. It helped. Mike, this seems like it might be a universally bad idea... It isn't a bad idea, as we need to protect our corporate networks. But there are unintended consequences, to be sure.

They are not being helpful and blame level3. I'm seeing period of high packet loss and poor throughput speeds. From what I can tell. Its a problem between qwest and level3 border routers. CL is an upstream of our provider. We complained about this to our provider, and our upstream complained to CL. CL's response was that this is an oversubscription problem due to a CL customer violating its ToS, and CL's lawyers were involved. That was two or three months ago. ...sigh...

I have seen the same from "firewall engineers" at large companies, people who, supposedly, have done "network security" for years. Even after showing them numerous Web sites detailing current best practices, especially Rob Thomas's fine site, these folks would not change their practices. Some days it is hard to not give in to the "I give up" feelings. ___ NANOG mailing list NANOG@nanog.org http://mailman.nanog.org/mailman/listinfo/nanog
