Restoring the Security Settings
When you establish a highly secure environment such as IPsec/IP Filtering or IEEE802.1X, you may not be able to
communicate with devices because of incorrect settings or trouble with the device or server. In this case, restore
the security settings in order to make settings for the device again or to allow you temporary use.

1. Select Menu > General Settings > Network Settings.
2. Select Advanced.

❏ Disable IPsec/IP Filtering

5. When a completion message is displayed, select Close.
The screen automatically closes after a specific length of time if you do not select Close.
