Hello,

I did some test here on an OpenBSD 4.3 using the same setup as you
(pf+217.76.32.61) and all is fine. The network stack works as
expected.

Do you've a scheme of the topology you use ?
What is the interface you're using for capture ?

Is 192.168.133.200 an internal interface of the box connected to
Internet or do you've another network box between 192.168.133.200 and
217.76.32.61 ?

With regards,

Jean-Philippe.
