IP Filtering

Overview

IP Filtering is a security feature that allows you to control access to Internet Services. IP Filtering allows 
you to prevent unauthorized access by TCP/IP (Transmission Control Protocol/Internet Protocol).

The IP Filtering feature provides security to the machine, by allowing you to register the IP addresses 
permitted to communicate with the machine.

1.

At your Workstation, open the web browser, enter the TCP/IP Address of the machine into the 
Address bar. 

2.

Press Enter.

3.

Click on the Properties tab.

4.

Click on the Security link.

5.

Select IP Filtering in the directory tree.

6.

Checkmark the IPv4 Filtering Enabled box.

7.

Enter the permittable IP Address(es) access to the device in the following IP Address table.

Note 

Enter in the IP address or a IP address range by using an asterisk (*) as a wild-card character, 

for example:

•

192.246.238.* is used to reference a subnet of host address.

•

192.246.* is used to reference a wider subnet of host address.

•

192.* is used to reference the widest subnet of host address

8.

Click on the Apply button to accept changes.

9.

If prompted, enter the Administrator’s User ID admin and Password 1111, and click on Login.

12. Enter the permittable IP Address(es) access to the device in the following IP Address table.

Note 

Enter the IPv6 address in form of CIDR convention. Prefix indicates the number of leftmost 

bits to be referenced.

Note 

For example:

•

2001:DB8:1234:215:215:99FF:FE04:D345 / 128 is used to reference a complete address. 

•

2001:DB8:1234:215:215:99FF:FE04:D345 / 64 is used to reference prefix address 
consisted of leftmost 64 bits only. 

•

2001:DB8:1234:215:215:99FF:: / 80 is used to reference prefix address consisted of 
leftmost 80 bits only.
