Finding newer compatible NIC hardware that is supported by Sophos firewall home is becoming increasingly difficult

This is becoming an exercise in frustration trying to find a newer device on which to run the Sophos UTM or XG.

Years ago when fanless dual NIC PCs used the Intel i211 chipset, it was supported by Sophos, despite them being made for "consumer use".

Now recently there are a plethora of very fast, efficient fanless PCs that have the upgraded Intel i225 chipsets, yet they are not supported due to them being designed for consumers according to what is said on the forums here.

Most home internet connections are becoming fast enough that the much slower CPUs used in these devices with the supported older NICs cannot keep up with the demands of the IPS.

Sophos still will not release the version 3 of Snort which supports multithreading which can take advantage of multiple CPU cores, instead relying on their proprietary  "Xstream Flow" technology which utilizes a separate CPU for just the IPS/DPI in the XGS devices which are marketed towards business.

It would be great if Sophos could simply put out a list of supported NIC chipsets, but they won't, and the hardware compatibility database (I used comic sans on purpose) is more like personal anecdotes of hardware that should work, the "updated" hardware compatibility list (comic sans again) doesn't even exist. support.sophos.com/.../KB-000034600

I suppose the only way to tell is to find out what linux kernel the UTM 9.7 is using and then see what Intel drivers are included in that kernel.

  • Neither option works unfortunately.  It stops after your post below:

    That might be something I consider. I have all but abandoned the idea of a fanless PC due to slow IPS performance, but will look at some refurbished Dell and Lenovo desktops that have the quad core i5 CPUs.

     I'm already considering KVM or VMWare on it along side Pihole. So, I think this might be the way to go.

    And, I know we've had more conversation than that with Patrick. A lot more.
