Has anyone gotten Filters to work on a 2nd or 3rd IP address for the external NIC? They seem to work perfectly for the first IP address but not for any other IP: External NIC: IP 1: 123.123.123.1 IP 2: 123.123.123.2 Filters: #1: Allow, ICMP ping response, External IP 123.123.123.1, All remote computers #2: Allow, ICMP ping query, External IP 123.123.123.1, All remote computers #3: Allow, ICMP ping response, External IP 123.123.123.2, All remote computers #4: Allow, ICMP ping query, External IP 123.123.123.2, All remote computers Results: Can ping 123.123.123.1 fine, but canot ping 123.123.123.2. It's almost like packet filters bind on nothing but the first IP. That is not the case with Server Publishing Rules. They work fine on the second IP. What is the explanation? John
