WebIn comparison, IP fragmentation occurs when an IP datagram is larger than the MTU of the route the datagram has to traverse. This behavior of fragmentation defeats some IPS and firewall filters who typically check the FLAGS in the header of the first packet since dropping this packet prevents the following fragments from being processed and assembled.
