ProxCP Admin - Manage User ACL
From ProxCP Documentation
This ProxCP Admin feature allows you to view and remove IP address access control on every ProxCP account.
In general, the ProxCP user ACL restricts an account from logging in unless the user's current IP address matches one on their ACL. This is optional and can be problematic for users with dynamic IP addresses.
This feature does not let you add IP addresses to a user's IP address access control list. A user must do this themselves to ensure they really want to restrict access.
