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 
server(Plan on trying to get inter-Asterisk boxes taking).  In a 
production environment though, it should be running on a separate box 
behind the firewall.
