Hmmm OK, I believe you! I'm sorry for the misinformation.

Yes of course, I didn't mean in any way to imply that the change was
wrong. I'm really sorry if my message made it sound that way. Thanks a
lot for your explanation of the current situation.

OK, I was just about to suggest that maybe I could make use of some of
the tunnel interfaces that we have in NetBSD, to make NAT happen
earlier, but I guess I won't suggest that then... ;-)
Just for reference I include a picture of my VMware situation below,
in case someone else has any clever ideas (read hacks).
Thanks again,
