Your google search skill must be low, because simply googling on 'ethernet bypass adapter' and following the first link would lead you to http://www.silicom.co.il/pgx.php?p2=127 where they list several models that are claimed to work with FreeBSD. > > The only thing that comes to me is this URL from Intel > (http://www.intel.com/network/connectivity/products/pro1000_quad_bypass_server_adapters.htm), > which I know by just looking at it, that thing won't come in cheap > price.

I am not at all sure that is a good idea. -- Erik Trulsson ertr1013@student.uu.se
