arp

My sonicwall TZ-210 is answering arp queries on the wan subnet (which my isp doesn't like), basically mapping all the wan ips to its own mac address, causing network havoc since it is not set to route those back to the main isp gateway.

How the heck can I turn this behavior off? I have already entered in all wan subnet ips in the static arp cache and left them 'unpublished' which I presumed would mean that it did not bother answering arp queries for them. Apparently it did not do the trick. Arp queries are still being answered unfortunately.

What can I do? Any suggestions?
