Hi I have searched all over for an answer to this but could not find anything... Please could someone explain to me what the best practice is when it comes to blocking ip addresses in a dhcp environment. If I block an ip address with eg. acl BlockedHost src 192.168.1.15 http_access deny BlockedHost What happens one day when the ip address changes to eg. 192.168.1.18? Will the user with the original ip adddress no longer be blocked? Please let me know what other people usually do in this situation. It would help a lot. Thanks Regards Dylan
