Thanks Jennifer, completion of the activity is now 100!!. The remark command was not allowed in the activity, so even you write correctly the acl statement the app gave you an error. Thanks again.

Hello there, I'm stucked with an acl problem. Attached to the message is the topology of an enterprise LAN with a server farm that I'm trying to protect using ACL's. Thre's also an addresssing table. The goals of the test (a paket tracer activity) are: 1. Prior to configuring access control lists both PCs can ping all servers and access all web pages. 2. After configuring access control lists, PC2, representing a legitimate inside user, can not ping any server but can access all web pages. 3. After configuring access control lists, PC1, representing a PC set up to maintain switch configurations, can ping servers in its own VLAN, can not ping other servers, and can not access any web pages. There must be 2 acl's one to permit web traffic to the server farm from pc1 and pc 2 and deny all other traffic and another one to permit dns traffic and deny all other. The acl's must be aplied outbound on router 1 and 2 in fa0/0.21, fa0/0.22, fa0/0.23 My choice, which doesn't work, is: access-list 101 remark web traffic access-list 101 permit tcp any 172.18.21.0 0.0.7.255 eq 80 access-list 102 reamrk dns traffic access-list 102 permit tcp any 172.18.21.0 0.0.7.255 eq 53 access-list 102 permit udp any 172.18.21.0 0.0.7.255 eq 53 access-list 102 deny ip any any What am I doing worng? Thanks.
