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?
