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?

Would you elaborate on the workaround that you did on the TZ170? Where do
you make the SAT entry?

Using the web GUI of the TZ, go to the network ARP table; in addition to
viewing, one can add entries. Also, I seem to be having a similar problem
with a W2K3 server directly behind the bridge instead of the TZ; I hope to
find a fix later today.
