advice on buying firewall hardware

Mon 22 October 2018

Several people have asked me recently what hardware I would buy today for use as a home firewall.

for a total of $176, including shipping. Links were accurate as of October 22, 2018.

This gets you a tiny box, similar in size to random commercial house router/firewall/wifi access points, which can run a standard Linux operating system with a complex firewall running at 1 Gb/s in and out, more RAM than strictly necessary, and an SSD which is both very large (and therefore can last a very long time) and boot the system quickly enough that you can do a reboot without losing TCP sessions.

I would also recommend a medium-sized USB thumb drive to set up as an emergency booting and backup device. Call it another $15 or so.

lies, revisited

Thu 17 May 2018

In ‘Lies, Damned Lies and Benchmarks’ (2014) I wrote about varying measures of CPU power versus perception of speed, and concluded that there were no order-of-magnitude differences in affordable CPUs. Three and a half years later, there ought to be some change in the market. What’s the best bang-for-the-buck these days?

I characterized an AMD Athlon 5150 as the low end: x86-64, 4 cores, 2GHz, and for a cost of $50 or so, a single-thread performance index of 804. For the top of the reasonable range, I selected the i3-4470, 2 cores producing a benchmark of 2240 each for …
