Regrettably since losing my lab I have not been in a position to easily

cool you disabled guest and babel. So far we've sort of ruled out
6in4 tunnelling, and syn flood protection.

Sounds like you are going to stick with -4 for a bit?

what I've been doing is mounting a usb stick, and just running continuo= usly
on the stick

tcpdump -s 128 -i ge00 -w ge00.cap &
tcpdump -s 128 -i sw00 -w sw00.cap &

This definately hurts performance...

And it's probably time to do a tcpdump on the connected device as well.=

In terms of other diags... (any suggestions?)

Hmm. OK, this brings back the device driver into the equation... I
WAS seeing dhcp and arp requests "getting through" from the captu= res,
and it seemed like arp in particular was getting through...

Well, I'd hoped it would be a confirming one rather than one opening up more questions.
