Used to run pfsense on a 433 MHz Celeron with 386 MB of memory until recently.
Perhaps the memory system is to low, the actual version will be running well, but in the near future the
support of the entire hardware will be changing step by step and so it might be a better thing to change
now, and go with 64Bit hardware that comes with AES-NI support too. So you might be able to run it likes
now for years without any issues.
What if it were not that particular hardware, can't you say where the hardware check is done and ways to disable it?
There will be not a switch to disable or enable it! As I personally know it, it was announced here in that forum or over the blog
on the netgate website, the following changes will be coming with the new version 2.4 and above;
No 32Bit support anymore, only 64Bit hardware will be supported
(but we got ARM support for two devices (at the moment) therefore or instead of)
No NanoBSD support anymore
(pfSense version 3.0 will be written totally new from ground and this is also very hard work and to the cost of much time)
AES-NI is a must be or must have option and not a can be or should be option
(Over the change of using Phyton over PHP and perhaps other things get also changed too)
Were they forced to stop building 32bit for technical reasons or was it a management decision?
Who should be pressing them to do so? But handling all, I mean, 32Bit and 64Bit, NanoBSD, rewriting version 3.0
totally new from scratch, AES-NI support, QAT, netmap-fwd and tryfwd or fast-fwd, failure and bug hunting, ARM
support, might be a bit to much at one time, perhaps this can be differ or changing at one days back who knows,
but I personally think it is more the lag of time to realize that all.
For a firewall only unit, with low power demands, you has more then one option at this time.
Official with support:
SG-2220
SG-1000
SG-3100
Alternatives well known and working:
APU2C4
Lanner units
Scope7 units
Qotom Intel i3
AxiomTek units
I personally would have a look for the SG-1000 or SG-3100 or APU2C4 as a replacement here.
