the kernel applies the rules in certain chains to the packets. For example, after receiving a new packet from the physical layer, the kernel activates rules in chains corresponding to input.
For example, if you’re sending data from Host A to Host B, as shown in Figure 9-1, your bytes leave the application layer on Host A and travel through the transport and network layers on Host A; then they go down to the physical medium, across the medium, and up again through the...
