All routers today implement policies for packet filtering and forwarding and most of them use what are called Access Control Lists (ACLs) to configure these policies.

Do some research on a commercially available router that uses ACLs (pick the router vendor of your choice) and describe in detail how ACLs are used and how the packet filtering is done.

Include specific examples of the ACLs in your answer, but note that you do not need to describe how the hardware implements the packet filtering and forwarding.

Make sure to identify the router you are describing. Note that most of the routers meant for homenetworks do not allow users to configure or view the actual ACLs, rather, they use a simple GUI interfaceto set router policy; such a device would not be a good example for this question. Also, many of thecommercial routers also provide a GUI interface to setting ACLs. For this question it is important thatyou describe the use of the ACL, not the GUI interface.
