I did find the thread alluding to an AWS/EC2 instance, & this blog post, but does not quite address the requitement.
The image(s) indicated either are no longer valid, or is way overkill.
Ideally I'm looking for something along the lines of a nano build (pfSense-2.1.3-RELEASE-4g-amd64-nanobsd-vga.img.gz), cabable of running on a t1.micro (free tier) instance, for testing/PoC.
Any solutions available, or is this something that I'll need to try & build from scratch myself?
t1.micro isn't going to happen, Amazon won't let it.
