I'm interested in crafting firewall rules that throttle connections
that have lasted more than a certain amount of time. (Most such
connections are P2P traffic, which should be given a lower priority
than other connections and may constitute network abuse.) Alas, it
doesn't appear that FreeBSD's IPFW can keep tabs on how long a
connection has been established. Is there another firewall for
FreeBSD that can?
