Is this about dynamic rules? Because looking at ipfw(8) you can only set that
globally via the net.inet.ip.fw.dyn_* sysctls. From the manual:
Dynamic rules expire after some time, which depends on the status of the
flow and the setting of some sysctl variables. See Section SYSCTL
VARIABLES for more details. For TCP sessions, dynamic rules can be
instructed to periodically send keepalive packets to refresh the state of
the rule when it is about to expire.
