well, i'm still discovering the 802.11 ...,
this is my question :
In an 802.3 network, machines that belongs to the 10.0.2.0 for example
are defined physically : you have to gain access to a physical port to
be in the subnet 10.0.2.0,
but with an aironet access point, ports are every where in the scope
of 30 meters of that point, what technique is used to limit the usage
of IPs from 10.0.2.0 for specific clients machines ?

Thanks

I'm not familiar with wireless protocols in detail, but I was talking to a
friend who was setting up a wireless LAN in an office. He said that the
WAPs can be configured to allow usage by MAC address, or they can require
the client to present an authentication key. Or you can disable this
completely, so that anyone can connect. The latter is quite common, which
is why people can walk down the street with their laptops and PDAs and
start surfing the net using the wireless LANs of businesses they pass by.

Some access points, Cisco, Symbol, support 802.1q which means you can trunk
to them and create wireless VLANs. A good design model would be to have a
management VLANfor the AP and a separate VLAN for wireless clients. The
Cisco Aironet 1200, running 12.0T, also lets you create a VLAN where
"unencrypted traffic" is allowed to flow. Soon IOS will be available for
this model and that will open up a lot more features.
