ideas enough.
as say, am using openBSD for nat, and serving local stats with mrtg and
smokeping (NO ACCESS TO EVIL WAN xD)

am not having squid configed as accelerator (it even wont let me, if i
add the tags, a check on config gives errors)

DNS is setup to serve local names only, and fetching DNS when needed extern.
