the ones I found where about routing or two NICs on the same 
subnet.. anyway, none seem to relate to the behaviour I had.. or 
rather, give the sysctl mib in question..

Yes.. that worked well..

they will be seperated again once our firewall is back & running 
and the standard router is taken off the net..
still, as I wrote in the reply to Dominic Marks:
 Isn't the request broadcast and the reply MAC addressed?

if I'm right on that, the "problem" (it's more cosmetic, really) 
shouldn't have happened, right..?

(at the moment the net looks like that:

  |     |
[sw1] [sw2]
  |     |
   | |  |
   | | {me}

the switch3 will be VLAN'ed again and properly connected once 
the firewall is back..)

Thanks for the help..
