Access Control Lists (ACLs) are a network security feature used to control and filter traffic entering or leaving a network device such as a router or switch. ACLs examine packets based on criteria like source IP address, destination IP address, protocol type, and port numbers, then decide whether to permit or deny the traffic according to predefined rules. They help improve network security, restrict unauthorized access, reduce unnecessary traffic, and enforce organizational security policies. The two main types of ACLs are Standard ACLs, which filter traffic based only on the source IP address, and Extended ACLs, which provide more detailed filtering using source and destination addresses, protocols, and ports. Properly configured ACLs are an essential part of securing and managing modern computer networks.

In reply to Rob.

I’m afraid there isn’t. I used GNS3 for these demos, and the GNS3 files are not backed up. You’d have to re-create the topology manually.

Glad you enjoyed the content!
