I dont know if these can handle full gigabit speed http://www.liantec.com/ ,
there are some benchmarks at http://www.kd85.com/liantec.html, the ones with
intel nics might just do it with a very recent linux kernel, there have been
some improvements recently I believe.
I have a sever at work that has dual onboard broadcom gigabit and 3 x intel
dual port gigabit pci express, those chipsets seem to work pretty good for a
firewall, 6 ports run gigabit speed and 2 100mb and the limiting factor is
the server disk speeds,i recently copied a 700mb iso image between two
windows 2003 boxes and it took about 6 seconds. I couldnt recommend the
server itself as its loud and expensive.
The Liantec Tiny Bus can take a 16x Pci Express Graphics Module, so perhaps
the 4 x Gigabit module is also PCI Express, and they do one with a Mobile
Core 2 Duo, if I wanted to build a quiet high performance gigabit firewall
thats the hardware I would be looking at.
If you do build something please let me know how you get on, I have a
similar requirement coming up in a few months time.
