The SBG6580 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 addresses range. IP Filtering is not enabled by default. This document describes how to enable and configure IP Filtering.
To Configure IP Filtering
- Launch a web browser, such as Internet Explorer, Firefox, or Safari. Enter http://192.168.0.1 into the address box, and press the Enter key. The Login page appears.
NOTE: By default the LAN IP address is 192.168.0.1. If the default address has been changed, enter the custom address in the address box.
 - On the Login page:
a.  Enter admin in the Username field.
b.  Enter motorola in the Password field.
c.   Click the Login button. The Home page appears.
NOTE: On firmware version 8.9.0.4 and later, the default admin password is required to be changed. Â The Change User Password prompt will immediately appear after logging into the Web manager with the default admin password. Â For assistance with the Change User Password screen, please refer to article # 18055 - SBG6580 (v.8.9.x): Prompt to Change Default Admin Login.
