DragonflyBSD's IPFW3 has below pros which are IPFW2 has not

1)Load-balancing
forward-option can be `round-robin' or `sticky'.

Above example can forward the traffic to 2 destination in round-robin.

2)States can be added/deleted using the ipfw3 utility.
Code:

ipfw3 state delete rulenum


3)States can be expire after some time
Code:
