Access-lists pose a logical problem which often has more than one solution. Can you think of a different set of rules or placements that would yield the same required access filtering?

Question is incomplete. it needs a topology diagram and also it needs Router R1 table. I assume User has access to the topology and Routing table.

Below Configuration will help to fix ACL problem
