I have setup an Open Source firewall/VPN terminator using an excellent AlixBoard 2D.13 and PfSense.
Actually PfSense release 2.0 has just been released, but I’ll upgrade as soon as possible and this post is related to PfSense 1.2.3
I think that AlixBoard 2D.13 + PfSense setup is a really good solution to have an OpenSource UTM box for small networks (SOHO): stable, cheap and open-source! In this post I will not explain how to setup PfSense on AlixBoard (you can find lots of great HowTo’s on Google) but how to improve your OpenVPN performance using the AlixBoard embedded cryptographic accelerator.
This post is based on great articles and site available on PfSense Web Site and Gorlani.com
