Question

How do I restrict devices from connecting to the Internet on my SBG6700-AC?

Answer

The SBG6700-AC includes a MAC Filtering option to define up to twenty Media Access Control (MAC) address filters to prevent devices from sending outgoing TCP/UDP traffic to the WAN via their MAC addresses. This option is useful because the MAC address of a specific Network Interface Card (NIC) never changes. Unlike IP addresses, they can be assigned by the DHCP server or hard-coded to various addresses. MAC Address Filtering is disabled by default. This document describes how to enable MAC Filtering.

To Configure MAC 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 SBG6700-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 # 18754 – SBG6700-AC: Web Manager Access.
Click the Login button. The Home page will appear.
Move the mouse cursor over the Advanced tab and select the MAC Filtering sub-link. The Advanced - MAC Filtering page will appear.
On the Advanced - MAC Filtering page:

a. Add MAC Address field - Enter the MAC address for the device to be blocked.

b. Click the Add MAC Address button to save changes.

NOTE: Repeat the above steps to add an additional MAC address. Supports up to twenty entries.
