I am looking to block certain IP Addresses at the firewall from accessing my network. It looks like someone is accessing our RWW and is trying to guess passwords. I access event viewer to obtain the ip address that is trying to hack in. I want to create a list on the ASA 5505 to block these IP's. I am new with the ASA 5505 and would like to use the GUI to do this. Can someone provide me with step by step instructions on how to do this.
