--LXx4g46d83wF7unj Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I assume that your pf(4) is enabled during these tests, you have "scrub" statements in the ruleset and removing "scrub" will restore the expected behaviour on 10.x? I am slightly amused that on 9.x with "scrub" you're getting the expected behaviour, because clearing FIN bit for SYN packets was the standard behaviour of pf since approximately at least 10 years, http://svnweb.freebsd.org/base/vendor-sys/pf/dist/sys/contrib/pf/net/pf_n= orm.c?view=3Dmarkup&pathrev=3D126258#l1242 Can you show relevant parts of the pf.conf from both machines and output from 'pfctl -s rules' if you are sure that both machines are configured identically pf-wise?
