{SPAM?} Re: IPv6 Deployment for the LAN

[richard at bennett.com (Richard Bennett)]

   The Wi-Fi MAC protocol has a pair of header bits that mean "from AP"
   and "to AP." In ad-hoc mode, a designated station acts as an AP, so
   that's nothing special. There are a couple of non-AP modes for direct
   link exchanges and peer-to-peer exchances that probably don't set "from
   AP" but I'm not sure about that.

As already said, wireless in infrastructure mode (with access points)
always sends traffic between clients through the access point, so a
decent AP can filter this.


How does the client determine that the traffic came from the AP versus
another client?
