It appears that all of the AS225/A2065's generate these spurious ARP
requests. I also tried changing the IP broadcast id to XX.XX.0.0. and a
couple of other things, but nothing affected it. The only other box
that appears to generate these types of ARP requests is the gateway
box, which periodically goes around polling all the machines connected
to it.

I heard a rumor that went something like this:

1) the hardware (firmware) was based on a previous spec for tcp/ip.

2) it is periodically sending the ARP request which never gets
satisfied since the current implementation for tcp/ip doesn't support
that request any more (or maybe the way it is being requested).

If anyone knows more about this, or what I should be looking for to
further analyze the situation (we have a network analyzer avaliable),
I sure would appreciate the information.

Has anyone noticed if the Amiga UX boxes have this same problem? (i.e.,
is it the AS225 software or the board which is causing this behavior?)
