The last I looked at this there was no multiple address support and this code is not attempting to add it. If you're saying that ip_learning, which this optionally substitutes for, now supports multiple addresses, I can look at adding it. The goal of this patch is simply to use only valid DHCP leases as the basis for anti-spoofing rules as a more secure method than the existing learning code. +-DLS
