Gigabit thoughput harware requirements



  • I want to build a firewall that will be able to push my gigabit network to the limit. I do a lot of large file transfers over the network and most of my machine already have Gb nics.
    The firewall will have 4 nics: internet, server, clients and a wifi subnet. Internet will be 24mbit adsl2+with an effective throughput of around 21mbit. I'll do a lot of traffiic shaping on the internet interface and a DMZ between clients and server. also the wifi subnet will use vpn.

    What hardware would i need for my firewall on a network like mine?



  • You need a lot of horsepower for this. First use nics that don't burn too much of your CPU time. Intel should be fine. As the traffic has to pass the PCI-bus you need a really fast one. PCI-X with appropriate cards should perform best. Trafficshaping and VPN is depending on CPU power. pfSense supports multiprocessor systems, so you might want to use more than one processor.



  • Check out the high-end pci-x and pci-e nexcom boxes.  I have a feeling you will want the dual xeon model.
