Cheap, but useable. I'd go for the 102 model though, since it has a 2nd
ethernet port. It was listed as $124CA

I'm currently testing 1 phone behind NAT. Works fine. The server is
running in the office, linked between an OpenVPN connection (TAP) and
NATted behind the TAP adapter's IP.

I'm playing around with 1 Asterisk box on my Mandrake Firewall, I've
opened up 1 port to allow the firewall to contact the Office Asterisk

behind the firewall.
