Check your cables. 99.9999% of the time I see 3/4 of the ARP
transaction one way but none of it the other way, it is a bad cable.
D to L
D sends ARP request
L receives ARP request
L send ARP reply
D does not receive reply because the wire pair from L to the hub or
from the hub to D is bad.
L to D
L sends ARP request
D does not receive it for the same reason as above.
