Firewall
When you click the Security tab, you will see the Firewall screen. You can add Firewall Protection and Filter
Multicast.
• Firewall Protection. To add Firewall Protection, click Enabled. If you do not want Firewall Protection, click
Disabled. If you enable Firewall Protection and click Save Settings, you enable the Schedule Rule, Access
Control, MAC Filter, URL Blocking, and Intrusion Detection tabs.
• Filter Multicast. Multicasting allows for multiple transmissions to specific recipients at the same time. If
multicasting is permitted, then the Modem will allow IP multicast packets to be forwarded to the appropriate
computers. Place a checkmark in the box to enable filter multicasting, if unchecked this feature is disabled.
When finished making your changes on this tab, click the Save Settings button to save these changes, or click
the Cancel Changes button to undo your changes.
