Restricting Access to the Machine (IPv6)

Return to Overview

If you are using this machine on a network environment, there are possibility that the machine may be hacked. By restricting IP addresses that can have access to the machine, you can prevent unauthorized transmission and access.

This section describes how to only allow computers with IPv6 prefix address with fec0:0:0:1::1234/64 to view and specify each settings on the machine using Remote UI or application software via IPv6 network.

  1. Press (Settings/Registration) → [Preferences] → [Network] → [Firewall Settings].

  1. Press [IPv6 Address Filter] → [RX Filter].

  1. Press [On] for <Use Filter> → press [Reject] for <Default Policy> → press [Register].

  1. Press [Specify Prefix] → specify the prefix address for IPv6 to allow data transmission → press [OK].

  1. Restart the machine.

The settings are only effective after you restart the machine.

Reference Information
  • Checking the Access Log

You can check the log of send transmission from this machine to the machine with the authorized IP address and the access log by the machine with the authorized IP address. The log can store up to 100 transmissions. Follow the procedures below to check the log.

Press (Settings/Registration) → [Preferences] → [Network] → [Firewall Settings] → [IP Address Block Log].

You can save the log in CSV format using the Remote UI.

[Settings/Registration] → [Preferences] → [Network] → [IP Address Block Log].

  • MAC Address Filter

MAC Address is a unique ID number for network machine. The address does not change even if the IP address is changed. In addition to the IP address, you can set the Send Filter as well as the Receive Filter for the MAC Address. Follow the procedures below to set the filter for the MAC Address.

Press (Settings/Registration) → [Preferences] → [Network] → [Firewall Settings] → [MAC Address Filter].

  • Specifying the TX Destination Domain

You can restrict the domain where the e-mail is sent. You can prevent information leakage by only allowing e-mails to be sent to an e-mail address with the specified domain. Follow the procedures below to specify the TX Destination Domain.

Press (Settings/Registration) → [Function Settings] → [Send] → [E-Mail/I-FAX Settings] → [Restrict TX Destination].
