Well, actually i want to know the limit(s) (related to amount of
data and number of connections) at which SMC Barricade 7004ABR
router allows only the already established connections and refuses
to allow any new ones.  This is all related to download a large
torrent via rtorrent.  Rebooting the router solves the problem until
i decide to restart the download.

not paid much of a look to ipfw.
