Configuring System Access via IP Filtering
By default, IP filtering is off, implying an Allow Any rule. Once you create an IP filter, Storage
Center infers that no one has access except for the specific access granted in the IP filter.
Make sure that the IP filters grant sufficient access to all System Manager users.
Caution: Be careful when configuring IP Filters. If an IP Filter does not permit access to
Admin users, it is possible to lock yourself out of the system.
IP Filtering creates access control list either by user type (for example, Administrator) or by
specific user. If you use IP Filtering, you must use it to control all system access. IP Filtering
creates an Allow Access Control List. If there is no specific allow rule, access is denied.
If you use network address translation (NAT) be sure to specify the IP address that is seen
by the Storage Center systems. It will not necessarily be the same as the local IP of the
machine you use to access the Storage Center GUI.
Managing IP Filtering

IP Filters. The first screen of the Manage IP Filters wizard appears:
