I've seen this in NG Feature Pack 3 as well.

It used to be that CP would drop any attempt to establish a new connection
w/ the same src port/ip and same dst port/ip unless firewall-1 tables have
been flushed out of the state of that connection from a previous use - with
this feature, CP would attempt sync'ng its own state w/ the actual state of
the client and server and convert the new 'syn' packet on the new connection
attempt to an 'ack' which in some cases does cause problems (I have seen
myself and had to change the behavior) and that is why your third party
vendor who might have seen issues w/ their application due this feature.

hope this helps.
