Question

How do I block local devices from accessing the Internet on my SBG6900-AC?

Answer

The SBG6900-AC includes an advanced IP Filtering option to define which local devices will be denied access to the Wide Area Network (WAN). IP address filters will need to be configured to block Internet traffic to specific network devices on the Local Area Network (LAN) by entering the starting and ending IP address range. IP Filtering is not enabled by default. This document describes how to enable and configure IP Filtering.

To Configure IP Filtering

Launch a Firefox or Safari browser. Enter http://192.168.0.1 into the address box, and press the Enter key.

NOTE: A browser message on Chrome, Edge, Firefox, and Opera, may appear when accessing the Web Manager. The message includes 192.168.01 uses an unsupported protocol and ERR_SSL_VERSION_OR_CIPHER_MISMATCH. The Web Manager uses an earlier version of the TLS protocol and does not match the version allowed by the web browser. Safari browsers on Apple PC and mobile devices are not impacted. The workaround to access the Web Manager with a PC is to use the Firefox browser and set the TLS version to 1. For workaround instructions refer to article # 19435 - 192.168.0.1 uses an unsupported protocol.
A security or private risk alert may appear on the web browser advising users to proceed with caution when accessing the Web Manager. There is no risk in proceeding to the Web Manager. For instructions to bypass the alert screen, refer to article # 18181 - Alert Message for Web Manager Access.
On the Login page, enter admin or a customized username in the Username field.
Enter password or a customized password in the Password field.

NOTE: On later versions of the SBG6900-AC, the Wi-Fi Security Key is used as the default admin password printed on the bottom white label. For assistance with Web Manager Access, refer to article # 18753 – SBG6900-AC: Web Manager Access.
Click the Login button. The Home page will appear.
Move the mouse cursor over Advanced on the top menu, and click the IP Filtering link from the drop-down submenu. The Advanced - IP Filtering page will appear.
On the Advanced - IP Filtering page, enter the Start Address of the range, which would be denied of access to the SBG6900-AC WAN.
Enter the End Address of the range, which would be denied of access to the SBG6900-AC WAN.

NOTE: Only the LSB (least-significant byte) of the IP address will need to be entered. The upper bytes of the IP address are set automatically from the SBG6900-AC Configuration Manager's IP address.
Checkmark the Enabled option to activate the filter.

NOTE: The maximum number of IP Filter ranges that can be configured is 10.
Click the Apply button.
