Man, I gotta wake up! What I am trying to say is: Packet transfer happens at the layer 2 (OSI model). Layer 2 is unaware of IP addresses. The 802.11 protocol states that the association has to be done at the level 2 (MAC) which produces several IP addresses with the same MAC address behind a a given AP. That issue is resolved via ebtables and the 'fix' is named WDS (Wireless Distribution System) Clear as mud? ET Ed Knapp writes: > The first unknown ( .3 ) looks like a Canon device.
