> You can easily use EBTables to (S)NAT the frames ethernet MAC address. I've tried the following two rules (independently): # ebtables -t nat -A POSTROUTING -j snat --to-src 11:11:11:22:22:22 --snat-arp and # ebtables -t nat -A POSTROUTING -j snat --to-src 11:11:11:22:22:22 --snat-arp -s 55:44:33:22:11:00 The result is that the traffic destined to Host A has the "new/faked" MAC address, but the return traffic back to Host B still has the faked address (and thus is ignored by the host). Does a corresponding DNAT rule need to be made in the PREROUTING nat chain? > If you need more help, just ask.

The ebtables project page states to post questions to the netfilter list (http://ebtables.sourceforge.net/contact.html) Thanks again. -tim -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
