If 4.3 still has the bug where it doesn't update its ARP entry for an IP address everytime it receives an ARP from that IP address, then those of us who occasionally change ethernet interfaces would rather see this time shortened than increased. Except for this, I think an ARP timeout of many hours is reasonable. David Bridgham
