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. WebJun 9, 2016 · So TCP packets have the DF flag set, which should cause an ICMP Fragmentation Needed packet to be returned if an intermediate router has to discard a packet because it's too large.
