 Sorry, my english is bad.  :(
 
 Patch to IPFW2 for adding restrictions of the traffic with use IPFW
 bytes counters.
 It include two parts:
 
 * First part is ipfw_bound.patch, this part add ipfw rule options "bound
 VALUE" and "check-bound NUM".
 Example:
 # ipfw add 100 allow ip from any to any bound 10K
 # ipfw add 200 deny ip from any to any
 
 While bytes counter of rule 100 below 10 KBytes, it work.
 
 Example:
 # ipfw add 100 allow ip from A.B.C.D to any out xmit internet
 check-bound 200
 # ipfw add 200 allow ip from any to A.B.C.D in recv internet bound 100M
 # ipfw add 300 deny ip from any to any via internet
 
 While bytes counter of rule 200 below 100 MBytes, rules 100 and 200 work.
 NOTE: Check-bound option search rule NUM like "ipfw skipto", but if rule
 NUM not contain bound option, then match fail.
 
 Second part is bound_change.patch, this part add control call to ipfw
 for boundary value change without bytes counter reset.
 Syntax:
 # ipfw bound NUM [set N] change VALUE.
