Several people have asked me recently what hardware I would buy today for use as a home firewall.
- Partaker N3050 B5
- N3050 CPU
- no RAM (1 slot DDR3L up to 8GB)
- no SSD (room for mSATA + 2.5” SATA disk)
- 2 x gigE + wifi 802.11 b/g/n
- 2GB DDR3L RAM
- 2GB RAM
- Kingston 120GB mSATA SSD
- 120GB mSATA SSD
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.
