3 NIC System for pFsense with Squid



  • Hi Guys.
    Basicly what  i wanted to do was build a small energy efficient system that runs pFsense with Squidguard.
    What i came up with was a Alix board but i was soon to realise that 256 MB Ram are just not enough.
    My problem now is that i cant find any decent board with passive cooling ,3 NICs,1-2gb RAM and small size.
    Is there anything u could suggest for me.
    Thanks in advance

    Not enough to run squid/squidguard?

    There is a number of Intel Atom mini-ITX boards with dual gigE NICs and passive cooling. Depending on your bandwidth requirements, you could use a VLAN capable switch as a "port multiplier" or use the expansion slot to take additional NICs.



  • i was already thinking about getting a itx board and just slam a pci network card on it but would it really work as the ones on board?
    And also dont the itx board consume more electricity than the embedded system like alix.

    Yes, subject to the limitations of the board's hardware. For example, you won't be able to get sustained Gigabit speeds out of a PCI board whereas (provided the CPU is sufficiently powerful and the NICs are of sufficient quality) you could get Gigabit speeds out of on-board PCI Express NICs.

    @neecross:

    And also dont the itx board consume more electricity than the embedded system like alix.

    If you want 3 NICs and more than 256MB RAM you will (as far as I know) have to get something that burns more juice than an Alix.



  • considering that i would have 20-30 ppl on my network at a time doing pretty much nothing but surfing the net and maybe doing some
    small backups is there any suggestion hardware wise u would give me or will just any Atom itx board do(considering it would have a pci slot for additional nics).

    How fast is your Internet connection?



  • 100Mbit/s



  • If I recall correctly, there have been postings claiming the author has seen more than 500Mbps through an Atom based system but I don't recall which Atom.

    If you start supporting additional networks and want to allow high speed traffic (say for backups) between the networks and the traffic has to go through an Atom you will likely find the cross network traffic is limited by the Atom CPU.

    But not with Squid/Squidguard, that was just routing.
