Linux wireless router (doable?)

[Cyber Source]

mmmmm familiar question that I seem to recall asking you about 2 months 
ago. I ended up going with a buffalo wireless router (like a linksys). 
For about $65,  I couldn't argue the 4 wired ports and the wireless that 
comes with it. Plus like other email posts, no moving parts, small, 
etc.. For added security, I turn OFF dhcp and only allow a range of 
addresses to the amount needed, no more.
