pass in quick on $EXTIF inet proto tcp from any to 192.178.78.6 port www
flags S/SA modulate state
I think scrub are used on the ext inferface
Check to see if you use scrub or not then that would answer your
question below.
So now to my question: is the above denied connections correct or should
they be allowed to the www server, eg. using S/SAFR in the pass rule?
While this is practical and safe, it is also unnecessary to check the
FIN and RST flags if traffic is also being scrubbed. From FAQ.
