    Hello Everyone:

    how can I block an ip range from a given ISP? I am a little familiar with access-list deny commands but not sure if I need to do anything else.

    Is there a way to block, let's say, an entire class A range by using masks? Like 123.*.*.*


    Thank you

    I figure it out.

    access-list outside_acl deny tcp any IP Mask
    access-list outside_acl deny udp any IP Mask
