Hello,
I am testing pf in an OpenBSD 4.1. This same configuration works fine on
OpenBSD 3.9, but in 4.1 it is not filtering anything, everything is passing
thru,
just like as if there was no 'block all'. What worries me most is that
anyone
on the outside can see my ssh service .
Is there anything wrong with the state of my rules? If i didn't
misunderstand ,
this rules should work just fine
Any ideas?
Thanks in advance,
Marcos

Marcos, 'keep state' and 'flags S/SA' are now default settings. Did
you read about what's new in 4.1[0], as well as the updated FAQ[1],
before upgrading your firewall?
