Hi guys,
Thanks for all the feedback on this question!
The atom-based machine I have is an MSI mini-itx bare-bones from newegg.
D330 cpu. We added 2 GB ram and a Hitachi 160 GB HDD, installe debian and
asterisk from the debian packages. It's been running flawlessly since last July
behind a linksys router. total cost was ~$200 CDN to put the mini-itx together.
It has only one mini-PCI slot which I am going to be installing a wifi card
(the case has the antenna/leads already there).
The Atom D330 is a dual-core 1.6 GHz cpu. If you are looking at atom-based
machines, take a look at the new offerings from intel in the atom series. A
couple of new ones have been released and more are in the pipe for later this
year.
Reza's suggestion for a usb adapter might work to add a second interface...
but if I can figure out vlan's I'd prefer to keep just the one rj45 interface.
Chad and Matthew suggested the vlan approach. I have a Netgear FS108P
switch available, it is a "smart" switch, not a "managed" switch, but so far in
my limited reading it appears that it should be useable to do this.
If anyone can recommend a primer on vlans, that would be most helpful.
thanks,
