--- Comment #3 from bsd@ddh.de1.cc ---
Update: The problem seems to center on the line "pass [log] all". When I
comment out the line and do "pfctl -F all -f configfile", the handshake to
185.60.115.40:443 works. Comment it in again, flush/reload, and the handsha=
kes
disappear again.

Same story with a slightly bigger config:

int_if=3D"em0"
ext_if=3D"re0"

rdr on $int_if inet proto tcp from any to any port www -> 127.0.0.1 port 31=
28

pass in quick on $int_if route-to lo0 inet proto tcp from any to 127.0.0.1 =
port
3128 keep state
pass all

-> Handshakes get dropped. Remove the "pass all", handshakes work.


Is this some intricacy of the rule syntax I'm missing or a legit bug?


PS: Sorry for not testing this earlier, a "pass all" ruleset seemed too min=
imal
to have any effect...
