    Learning about named ACL, I came accross with a senario where it suggests to
    "use the _established_ keyword to maximize client system security. It will
    allow host clients to receive traffic from sources that were sent TCP
    request".

    Example:

    router (config)# ip access-list extended myacl
    router (config-ext-nacl)# permit tcp 0.0.0.0 255.255.255.255 192.168.12.0
    0.0.0.255 established


    Any link, feedback, explaination, will be greatly appreciated!

    I guess security people do not have deep knowledge of ACL.
