Extended Access List (ACL) for the Cisco CCNA - Part 1

A beginner's tutorial on writing an extended access list (extended ACL) for the Cisco CCNA and CCNA Security. The demonstration uses the Cisco Packet Tracer software.

In part 1, I demonstrate how to write an extended access list and where to apply or place it in the network.

I tried this approach to stop Network A talking to network B, but to allow network B to still talk to Network A. Pings from A to B are blocked as they should be. But pings from B to A just time out. Any ideas what has gone wrong?
