Now that I switched from virtio to 82545EM all my networking problems
disappeared.

Appart from pf, I had also some other small networking problems that I
thought were apache/php related, but were in fact due to virtio.

virtio is clearly the culprit, but I can't say if it is FreeBSD or
VirtualBox related

Guest: FreeBSD 9.2 amd64
Host : FreeBSD 9.2 amd64
VM   : VirtualBox 4.2.18

I can provide more information, if you tell me what to look for.
