    Securing Server Access - University Campus Network


      I could do with some guidance an the task to:-

      'Disable ICMP across the DMZ and allow only established connections into the internal network.'


      I have created access list as follows


      access-list 103 permit tcp any any established

      access-list 103 deny icmp any any echo

      access-list 103 deny ip any any


      and applied to interface fa0/0 in the inbound direction on the Admin-MDF router.


      Am I missing something? Any clues appreciated as I am well and truely stuck.
