IP ACL
Overview
The IP ACL (Access Control List) Tab provides additional security by allowing Administrators to limit the client
machines that can access the unit. Administrators can specify either specific IP addresses or ranges of IP addresses
of machines that
cannot connect to the unit.
For convenience, all desired IP addresses and subnet addresses can be stored in the IP ACL list and allowed or
disallowed as needed.
Figure 48 IP ACL Configuration Display
Configure IP ACL Parameters
•
IP ACL Enabled : Check this box that enables this feature
•
IP Address Range : Valid IP address range that will be restricted
•
Subnet Mask : Subnet mask address
Important! Please make absolutely certain that all IP addresses have been entered correctly before
enabling IP ACL. If not, you may be locked out of the unit and be unable to access the unit in the future;
the only way to restore access to the unit is to perform a factory reset, removing all user-defined values
that you have programmed in and forcing you to reconfigure the unit completely.
Only valid subnet masks can be entered in the interface. IP addresses 0.0.0.0 and 255.255.255.255 cannot be added
as they are reserved IP addresses. Access to the unit is determined by doing a binary AND of the configured IP
address with the specified subnet mask, and comparing this with the result of the binary AND of the IP address of
the machine trying to connect to unit and the specified subnet mask. If the results are the same, access to the unit is
denied.
