I would say this is the wrong solution. Prevent your customers from spoofing is the first step, then ask them to fix their broken CPE.

I daresay that after ten years of discussion NANOG has reached consensus that implementing BCP38 is a good thing and that all networks should be encouraged to do so.

Net neutrality has not been discussed completely to death yet but I'm pretty confident in stating that squeezing consumer connections further down each time some blog hypes up yet another "The Internet is melting!" threat won't scale.


If NETGEAR is listening on the WAN side vs the LAN/INSIDE they need to step up and issue fixed firmware, even if the device is older. Should be a simple fix.

I don't think anybody would disagree with this statement. Netgear did get into action when they DDoS'ed a university's NTP servers; perhaps similar sticks can be shaken in this case.

(Is Netgear one of the brands involved?  Usually they're better.
 Pardon me for not reading the whole thread and the other five)


I think it's easier to just classify an open-resolver similar to an open-relay without having to invoke the consumer mindset.

Two posts up in this thread we were talking about net-wide blocks without individual proof of open relay or equivalent status.
