A common, $70 USD router with enough reflashable memory that you can 
reflash it to DD-WRT makes an ideal firewall. I have a Netgear 
WNA3500-something here, protecting my 5 machine home network.  It has 
just sat there and ran for several years now, drawing about 5% of the 
power an old wintel box drew for several years prior to it.  Its 
programmed to forward one port to this machine, which is how you can see 
the web page in my sig.

When looking at routers, it must be reflashable, and must have 4 megs of 
flash, with 8 megs being even better.

Network access for my home network machines is utterly transparent, but 
no one has come in to do any dirty work in a decade or more.  I'm 
probably foolish, but I haven't worried about the black hats in years.
