>Description:
I had that rule on my 5.4:
pass in log on $if1 proto tcp from x.x.x.x to y.y.y.y port 22 flags S/AUPRFS synproxy state
This rule was working properly until I upgrade to 6 Beta 4. I can't connect anymore from x.x.x.x to the server using SSH.
To fix the problem, I replace the synproxy option with keep state.
