Notes:
- everything else on 10.1.[1,2].0/24 is switched off currently - the
arp list is in fact complete
- ed0 has no IP address (outside the firewall, for sniffing purposes)
- I'm not experiencing any networking issues
- IIRC this happened on Free BSD5.3, too
Is this expected behaviour? Just curious.
Best wishes,
boink
