ACL’s are needed to keep the Students out of areas that they are not supposed to be in. Students need access to Email servers, DNS servers, and HTTP Internet. Our ACL allows students access to these things and blocks all other packets. The administration side will have full access to the curriculum side. We do this by giving permission to certain types of packets and not other types to travel out of the student interface E0 on the router. The commands that follow are the router commands to implement the ACL’s for the students. Sunnyslope(config)#access-list
101 permit tcp 10.11.0.0 0.0.255.255
10.10.0.0 0.0.255.255 eq
SMTP Sunnyslope(config)#access-list
101 permit tcp 10.11.0.0 0.0.255.255
10.10.0.0 0.0.255.255 eq
HTTP Sunnyslope(config)#access-list
101 permit tcp 10.11.0.0 0.0.255.255
10.10.0.0 0.0.255.255 eq
DOMIAN Sunnyslope(config)#int
