3.3.2. IP filter Settings
Each ET-7000 series module contains an IP filter that can be used to control access to the
module, thereby preventing unauthorized access from unknown IP addresses. The IP filter can
be granted across a range of IPv4 addresses, such as from 10.0.8.1 to 10.0.9.22 or to a single
IP address, with a maximum of ten permission rules. Once the IP addresses that have been
granted access permission have been entered, and the rule activated, the ET-7000 module IP
filter will guard the TCP/IP connection by restricting access to any unauthorized IP addresses.
There are three methods of restricting or granting access permissions.
z
Allow Only a specific IP address
Enter the same IP address in both the
From
and
To IP Address
text fields
z
Allow Hosts within a specific IP address range
Enter the first IP address in the
From IP Address
text field, and enter the last IP address
in the permitted range in the
To IP Address
text field.
