Allow and Deny list handling

IP addresses can be included in one, both, or neither of the Allow and Deny lists. To specify how HCP should handle access requests from IP addresses that are either included in both lists or excluded from both lists, select or deselect the Allow request when same IP is used in both lists option. The table below describes the effects of selecting and deselecting this option.
