Summary:                    Answering ARP with invalid response when queried by
firewall
Description: 
When a SonicWALL TZ170 (WAN port) sends ARP queries through a busybox
system acting as a bridge, responses with a HW addr of 00:00:00:00:00:00
are sent instead of the correct address of the Cisco router on the other
side of the bridge. This is consistent when using different TZ170s.  A
SonicWALL engineer could not find anything wrong with the TZ170 operation.
 To make sure it was not a hardware level issue I tried using a hub between
the firewall and the bridge -- no difference.  Although, both the TZ170 and
the bridge box seem to work correctly when an ordinary PC running WinXP is
substituted for the other box and I try simple ping/arp tests.  The
workaround is to make a manual SAT entry on the TZ170 with the router's HW
and IP addresses.  How transparent is the bridging busybox?

This seems similar to issue http://busybox.net/bugs/view.php?id=154
Are there any specific tests I should do to help isolate the problem?
