IPv4 Filter function controls the access to the Brother machine from a specific computer (IP address). It prevents unauthorized access and reduces unnecessary printing costs.You can specify not only by IP address but also by subnet mask, therefore you can easily specify several IP addresses.

Functions you can restrict the access

• Print from computer
• Scan
• Access from Web Based Management

5. Register the IP addresses you want to accept or reject the access.
   The below explains how to register the following IP addresses ((1) and (2)) as accepted IP address.
   
   (1) IP address: 10.111.111.111
   (2) IP address: 10.112.0.0 - 10.112.255.255
   
   Check Accept the following Addresses in Access Setting and enter the IP address and subnet mask in the Address and Mask fields as shown below.
   *In the case of (1), you do not need to enter the subnet mask in the Mask field.
   
6. Click Submit.
    
7. Click Yes and re-start the Brother machine.
   On the IPv4 Filter page, you can see the subnet mask is automatically entered in the Mask field for the IP address (1) you entered in Step 5.
