Sophos UTM Home Edition (Score 1)

Go download: https://www.sophos.com/en-us/p... You'll have a free licence for 50 ip addresses per side. Beauty is.. its linux; supports more hardware options than pfsense. I use this to do exactly what you're wanting to do. I built small cheap computers($250 a pop from newegg, tri nic'd) to be the "FW", installed the UTM box to every family household that needed one and setup site-to-site VPN between them. Works perfectly and it easy to manage.
