Hello, im studying for ccna2 skills test. I have obtained some question tips from my friend but i do not know how to solve this part: "The company also has a server pool in the 209.0.0.0/24 network. The server pool addresses are divided in half. The servers in the upper half of the address range are reachable only by management hosts using all possible IP protocols. The servers in the upper half of the address range are not reachable by production hosts using all IP protocols The servers in the lower half of the address range are reachable by all LAN hosts using all possible IP protocols. The servers should not be accessible by any other hosts."

This is regarding ACL and what input to type into the router to solve the above problem. Any solutions?
