Re: MAC Filtering
Never rely on MAC filtering for anything. MAC spoofing is utterly trivial. That's not to say don't enable MAC filtering and know what's on your network, just don't treat it as a layer in the security onion.
IPSEC is your friend if you really want to be secure over 802.11. There's the obvious trade-off in CPU cycles and throughput overheads, natch, but you need to define your priorities and compromise accordingly.
