"Identification" field of IPv4 header The IPv4 header is correct, but the payload is TCP, and TCP has its own header because it is a separate protocol. The protocol at each network layer (in your case, ethernet, IPv4, and TCP) each have their own headers. It may be simpler to start with UDP instead of TCP because it has a small header, and the checksum in its header is optional. TCP reset is identified by the RESET flag in the TCP header set to 1. You can then review the Security event logs to see for a packet drop on a particular port-IP and a filter ID associated with it.

The first 20 bytes are the fixed IP header, followed by an optional Options section, and a variable-length Data area. Note that the Type Of Service field is shown as originally defined in the IPv4 standard. That’s a pretty big table, because the IP datagram format is pretty important and has a lot of fields that need explaining. TCP/IP is a communication protocol that establishes a connection with another computer and ensures that the packets are sent and received successfully.

Figure 2 shows a typical (and minimum length) TCP/IP datagram header.6 The header size is 40 bytes: 20 bytes of IP and 20 of TCP. Unfortunately, since the TCP and IP protocols were not designed by a committee, all these header fields serve some useful purpose and it’s not possible to simply omit some in the name of efficiency.

On the webserver, TCP reads the header and finds the application address. The transport layer puts its header in the beginning and sends this complete packet (TCP-header + app-data) to the IP layer. On the same lines, The IP layer puts its header in front of the data received from TCP (Note that data received from TCP = TCP-header + app-data). So now the structure of IP datagram becomes IP-header + TCP-header + app-data. TCP wraps each data packet with a header containing 10 mandatory fields totaling 20 bytes (or octets). Each header holds information about the connection and the current data being sent.
