Tips for getting cheap used x86-based firewall with full Gbit NAT (a PC Engines APU) if you are in the US

So basicaly how do you install a new OS on this velocloud device ?

What @takimata said, even though I actually had issues with getting an USB flash drive to boot
on my Roqos RC10. Ended up removing the drive, and dd:ing the image to it, on another computer.


I wonder if that's anything like the issue the Sophos SG1x5s have with booting from USB. You need to go into the BIOS and set Advanced > USB Configuration > Port 60/64 Emulation to "Disabled". Only found this out from the pfSense forums. But yes, pulling the drive and writing from another device works, if it's a standard SATA device. Obviously if it's mSATA or m.2 you'll need a suitable adapter or mobo slot.

See VeloCloud_EDGE_500-N for details. Mine didn't come with a power supply either. I used one I had for a Sophos XG 115 successfully.

Mine was purchased AS IS untested and the onboard SATA NAND is not recognized so it booted into EFI Shell. I was able to boot EFI X86 OpenWrt from USB, but couldn't figure out how to get network access. There is a mini-USB serial port accessible after removing the cover. The EDGE 540-AC case actually has a popout in the case to allow access to serial, the 500-N does not.

what's the barrel size of the XG115 charger then :slight_smile:

I've searched for some further velocloud information (which is scarce, and I don't have the hardware myself), the biggest issues with this hardware will probably be:

Sources, based on a heavily forked OpenWrt (chaos calmer derived), should be available from


It's listed in the Power section of the wikidevi entry!

How did you find this! I wasn't coming up with much of anything and based on the fact that VeloCloud was acquired by VMWare didn't give have much hope.

I don't know if it's a problem with all the Roqos RC10 or just mine. Anyway all problems gone with a powered usb 3.0 hub. All test usb devices are stable.

For now I'd advise against purchasing a VeloCloud device unless you are ready to do some serious development work as it isn't going to be easy to get the network ports up and recognized!


any J4125 mini PC like this, can handle full gbit nat ?

I'd say it's decent, since it appears to have intel 2.5gbit NICs.

And those work out-of-the-box? I also heard some rumors that certain versions of those are buggy...

intel i225 with stepping prior to B3 are buggy.


I believe so, and yeah, some versions are buggy.

Quad core Gemini Lake processor and 5 Intel NICs, ready to use with RAM and SSD, brand new for < $175USD? Where can you do better than that, even before factoring in that they're 2.5GbE?

Plus shipping.

Plus god knows how much in taxes, vat, and fees.

The costs of delivery affect much more than this one device. Free shipping is not the usual case, and many forum users here have limited choices in their own countries and have no option except to order from other countries. You should probably open another topic to complain about it; it seems wildly off-topic here.

Out of curiosity, are you affiliated with aliexpres? Not that it would bother me as I'm pretty sure this is my next router should my existing $35 US core 2 duo (used of course) gives up the ghost.
