Thanks for your guidance, my only concern with the original request, is
that that 12 mbps is coming from some 20,000 email users and 4,000 web
sites, so it not necessarily big chunks of datam, but perhaps a lots of
small chunks, which may eat up the 30,000 states is what i fear.

I believe that's generally correct. If you look at 5 different web
browsers on 5 different OS's, you might get all different results
though. Also, for example, some people configure Firefox to fetch
multiple items on a page simultaneously, so you might have 5 or so
simultanous with something like that.
The vast majority of states will be quickly removed from the state
table, as the connections will be properly closed. If anything,
ipfilter is a bit overzealous in cutting off states (not that other
firewalls aren't - my PIX firewalls drop more legit reply traffic than
my m0n0walls). My point being, states don't hang around for long. A
few won't get closed properly for a number of reasons, but will get
timed out after an hour and a half (IIRC that's the default in 1.2, if
not exactly that, it's close).
I believe I stated this previously, but with only 12 Mb of
web/mail/DNS/etc. traffic at peak times, I seriously doubt if you're
using > 30K states. I'd be surprised if you're using half that many.
