Somewhat related to this discussion:

yesterday I ran nessus against my firewall (twin-vr, netbsd-current
and pf), and nessus reported that it had detected the "Etherleak"
vulnerability, where ethernet frames are padded with data from some
other data packets. I checked the vr driver, but it seemed like the
padding for the ethernet frame is set to zero, and there should
be no problem. I didn't yet have time to investigate whether the
problem is really in the vr driver or in nessus. Just wanted
to mention this as it might be related to the other problems.
