Filtering connection on wlan using mac address and shorewall

["Micha Feigin" <michf@post.tau.ac.il>]

I am just setting up a local wlan based network at my house.
I would like to filter incoming connection based on mac address (only allow
known computers) appart from having encription and authentication on the network
(which I am still working on figuring out how to setup).

I am using shorewall as the firewall and I was wondering how to set this up.

Thanks
