Using the Static IP List to Block Devices
You can use the
Static IP list
to control access to your network. You can block
access by devices that are not on the list or do not have the correct IP address.
STEP 1
Add devices to the
Static IP list
as described in
About Static IP Addresses (for
IPv4 Only), page 66
.
STEP 2
Enable or disable the following features:
•
Block MAC address on the list with wrong IP address:
Check this box to
prevent a computer from accessing your network if its IP address has been
changed. For example, if you previously assigned a static IP address of
192.168.1.100 and someone configures the device to use 192.168.149, the
device will not be allowed to connect to your network. This feature
discourages users from changing their device IP addresses without your
permission. Uncheck the box to allow access regardless of the current IP
address assignment.
•
Block MAC address not on the list:
Check this box to block access from
devices that are not included in the
Static IP list
. This feature prevents
unknown devices from accessing your network. Uncheck the box to allow
access by any connected device that is configured with an IP address in
the correct range.
