MFC r222582:
O_FORWARD_IP is only action which depends from the result of lookup of
dynamic rules. We are doing forwarding in the following cases:
o For the simple ipfw fwd rule, e.g.
fwd 10.0.0.1 ip from any to any out xmit em0
fwd 127.0.0.1,3128 tcp from any to any 80 in recv em1
o For the dynamic fwd rule, e.g.
fwd 192.168.0.1 tcp from any to 10.0.0.3 3333 setup keep-state
When this rule triggers it creates a dynamic rule, but this
dynamic rule should forward packets only in forward direction.
o And the last case that does not work before - simple fwd rule which
triggers when some dynamic rule is already executed.
