Cisco routers with ACL (access control list) capabilities interconnect the network shown below. Write ACLs to accomplish each of the following specifications.

Notes:

1. Each specification is a separate question.

2. Assume that the network set up is standalone in that it is not connected to outside networks.

3. You may also assume that no new networks or hosts will be added to this network.

(a) Prevent traffic from workstation 20.163 from reaching the workstation 70.5 and the tower box 70.2. Traffic from all other hostsetworks should be allowed.

(b) Prevent traffic from 80.0 network from reaching 10.0 network. All other traffic must be allowed.

(c) Workstations 50.75 and 50.7 should not be allowed web access on tower box 70.2. All other workstations can.

(d) 80.16 can telnet to 40.89. No one else from 80.0 can telnet to 40.89. Any other host from any other subnet can telnet to 40.89.

(e) 70.5 can ftp to the Edmonton router. No other host can.
