Hi there,
Not sure about pearls of wisdom, but I might be able to assist. I've used Alix boards for years with nanobsd on CF media. I recently (last few months) switched to APU2 boards with 16GB mSATA SSD drives. I had quite a wrestling match setting up the first, but all good now. I have about half a dozen out in the field with:
- APU2 (c2 & c4 mix)
- 16GB mSATA SSD
- pfSense 2.4-Rel
In order to move from 2.3 to 2.4 I had to drop nanobsd. I now install full 2.4-Rel onto the above systems - all have been rock solid since day one. Note that I also use OpenVPN for remote support to all of my sites, it's stellar also.
I'm happy to help all I can, but need to head out to some customers now. I'm in the UK and it's 14:30 at the moment - not sure where on the planet you are. If you think I might still be able to help you (you might have solved it by now of course!) then leave a reply here and I'll get back to you when I'm done for the day.
Regards
Ian
