Anybody make something similar with dual ethernet? I'd like to replace my aging Alix-based home router/vpn (http://www.pcengines.ch/alix2d3.htm) with something like this.
If 100M is enough for you, I'm developing a new board with 2 RJ45 for industrial ethernet, which has a 40 pin connector compatible to that of RPi B+, but the circuit is adapted from beaglebone black. It's scheduled for end of January 2015.
So, $315 and ~15W max. I bet this could serve a small office well. Someone should get this down to $200 with minimal specs (and no video or audio).
It has dual Realtek NICs; it runs pfsense and openVPN well, and you can also run squid and snort if you're into it (I haven't learned how to use them yet, but I plan to).
The mirabox has dual ethernet and arch linux support is good. The box is a little expensive and I have never got wifi to work but as a router/firewall it does the job:
The Novena board looks pretty shiny for this. Mine should come in any day, and I plan to at least try it out for this purpose. Unfortunately it isn't dual gigabit though, so it'll bottleneck my internet a little bit.
