Solving Problems for Advanced Security

Restoring the Security Settings
When you establish a highly secure environment such as IPsec/IP Filtering, 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.
Disabling the Security Function Using the Control Panel
You can disable IPsec/IP Filtering using Web Config.
1. Access Web Config and select the Network Security tab > IPsec/IP Filtering > Basic.
2. Disable the IPsec/IP Filtering.
Problems Using Network Security Features
Forgot a Pre–shared Key
Re-configure a pre-shared key.
To change the key, access Web Config and select the Network Security tab > IPsec/IP Filtering > Basic > Default
Policy or Group Policy.
When you change the pre-shared key, configure the pre-shared key for computers.
