Hardware for embedded FreeBSD/OpenBSD custom router/firewall ( Ent. firewall, ADSL ro

[Bsaidus]

Hello.
I am investigating these days the possibility of embedding FreeBSD/OpenBSD in hardware like ADSL Modem (modem adsl ) , or firewall dedicated hardware.
So my questions are:

• Could you point me to a hardware adequate for an ADSL Modem/Router like Huawei or Dlink ones.
• Could you point me to a hardware adequate for a firewall appliance.
• Where can I buy these hardware.
• Is these hardware support FreeBSD/OpenBSD.

Thank you.

Possibly a Raspberry Pi, many do use as such systems....on Linux, but they do have some BSD versions of the O/S.

There are many hardware appliances from pfsence/opensense. You can also look at the pcengines boards, even they are discontinued.

According to the youtube video linked below¹, the fujitsu s920 is a good machine which can be converted very cheaply into a router with an ethernet card. All for less than 70€ or even cheaper if you strike a good deal on the second hand market.

On it you can install OpenWRT, OPNSense, IPFire or VyOS.

Don't bother with FreeBSD, pf(4) is the gold standard for firewalls and only OpenBSD gets the latest version.

For low power arm64 options, Banana Pi makes a series of dedicated router boards including one with a Rockchip RK3568. Per per page, this should be supported.

There is a bootlog of OpenBSD running on an older Banana Pi R1 but searches for R2's came up empty. This would be theoretically possible but you would be breaking new ground.

I looked at this and there are cases/power supplies available. My paranoia/security needs are real but not astronomical. I ended with OpenWRT on a MediaTek
MTK7621 based Linksys EA7300. I found a factory refurbished one for ~$40USD and have been happy with it.

FreeBSD does have a dedicated router project which relies on a separate firewall. The forums resident Network security
and routing, expert @jggimi, has advocated for a separate firewall in the past.
