I have a F4C box on my network which i access off of my Ubuntu laptop. I have ssh up and it serves my network fine. I forwarded ssh(p22) through my one router and then again from that router through a VoIP router which has a direct connection to the internet. the F4C box has a static local Ip of 192.168.0.3.
ifconfig of F4C box
