Hello

from ealier 6.0 there is problem with synproxy in pf filter:
this one 6.1-PRERELEASE #2: Wed Mar 15 02:02:37 MSK 2006

pf.conf just with single rule
pass in quick on lo0 proto tcp from any to any port 22 flags S/SA =
synproxy state

result
telnet 127.0.0.1 22
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

and it's hangs

pfctl -s rules -v
No ALTQ support in kernel
ALTQ related functions disabled
pass in quick on lo0 proto tcp from any to any port =3D ssh flags S/SA =
synproxy state
  [ Evaluations: 966392    Packets: 0         Bytes: 0           States: =
1     ]


 pfctl -s state
No ALTQ support in kernel
ALTQ related functions disabled
self tcp 127.0.0.1:22 <- 127.0.0.1:44819       PROXY:DST

without synproxy all is ok
=20
There is PR 86072 about that with unclear results.
