The ebtables project is exactly for doing some transparent filtering.
Just set up a bridge between your ISP and your network depending
on your Internet connection type.
(ex.: you wouldn't be able to filter PPPoE stream yet.)

For more information :

http://ebtables.sourceforge.net/

*note:* bridging filtering is part of the linux 2.6 series
             there's a patch for 2.4
