If you have a reason that you want to use gumstix parts for this,
others besides me will do better to advise you regarding what to buy...
But, if what you are trying to get is an inexpensive Linux box to do
routing, firewalls, NAT, and such, you might do well to take a look
at something like DD-WRT (http://www.dd-wrt.com). This is a prebuilt,
open-source linux kernel with a very good package of routing software;
it runs on a broad range of off-the-shelf cheapo wireless and wired
routers that you can get for $50-$100 or less.
I've got three Buffalo routers here running DD-WRT, doing some complex
networking things in my lab. I bought them from bestbuy originally.
You overwrite the factory firmware by following DD-WRT's directions to
download the DD-WRT firmware image to them using TFTP when they are
booting. From then on they run linux, etc. They have a web
management interface, but you can also log into them with telnet,
install other logging or monitoring software, do complicating mucking
with routing tables and inetd, or whatever. I've found the
performance, latency and such, and reliability to be really, really good.
I've found that not a lot of people know about this, so I just thought
I'd post this answer here.
