Summary
Invalid Packets would be fragments, invalid headers, and other traffic that does not conform to standard IP rules. Most of these packets are caught by our Traffic Normalization filters (7101 to 7199), on by default), to keep the network clean. These filters are set to BLOCK only, so as to not flood the system log. If you wish to view the filters, perform a search and look for the words "Traffic Normalization" in the filter description.
