VK-T40E on gbps wan



  • Hi,

    I currently run m0n0wall on ALIX (my Liantec box with pfsense died and doesn't want to boot anymore).
    An upgrade is sorely needed.

    I live in Tokyo where Gbps WAN are a distinct possibility ( 2 ISPs offer 1gbps and Sonet just came in with 2gbps wan) I would like to know what would be the throughput of VK-T40E for basic routing (no snort, just firewall and routing) .

    Will it accommodate a 2gbps wan ?

    Thanks
    Quentin



  • From https://www.pfsense.org/hardware/ :

    501+ Mbps
    Server class hardware with PCI-e network adapters. Multiple cores at > 2.0GHz are required.



  • VK-T40E/APU only manages around 450mbit of basic routing and firewalling.
    You could go for the C2558/C2758, there should be no problems with throughout.

    Yep the Rangely boxes are certainly suitable. The hardware sizing guidelines are somewhat out of date. Even a relatively modest CPU will push >1Gbps of firewall/NAT traffic these days. The, now older, Celeron G530 has been shown to be capable for example.

  • Apologies for bumping, but this is the exact issue I have just run into. I have a VK-T40E (w/SSD) that I purchased last year. I just moved to an area with Gigabit FTTH, and I was confused to see the ISP's modem pulling 750/500, but my VK-T40E could only get 300/200.

    I used to use a lot of heavily filtering (snort, etc) - so I did a config reset, to where the only change I made to a default config was to enter the pppoe credentials. There was no improvement.

    I see the post above where, at some time, the store told us this box was only good for 450 Mbps total (which I'm not close to really) - but I studied this purchase for a week and never saw that.

    Am I just SOL? I thought I was purchasing a decent bit of kit, I didn't realize it was so underpowered. Normally I run DD-WRT on whatever I can find; this was my first big purchase to what I thought was a great appliance.

    Thanks for any comments you can give.

    And if you now buy another box for your pfSense and then the ISP is offering 2 GBit/s or 3 GBit/s this box
    would then also once more again outdated, this game can be easily made thousands of times and you
    will loose every time again. But why now should be the pfSense store the guilty one?

    P.S.
    Without activated PowerD (high adaptive) measured with iPerf from PC to PC something around
    or nearly ~450 MBit/s is a really good number, but with activated PowerD (high adaptive) it
    was pending something between ~650 MBit/s till ~750 MBit/s owed to the file size.  So this
    would perhaps be a good point to start to tune your box a little bit.

    About the only option you have to seriously increase the throughput on the APU is to fit Intel miniPCIe NICs. I've not tried that myself (or even seen it) but one user here reported ~600Mbps. Of course his testing may have have different to yours. They aren't that cheap though and require modifying the case or re-casing etc.
    300Mbps does seem low, I've seen reports of 350-450Mbps in real world conditions. Again the testing methods could have been very different.
