7.8.1 | Network Filters

The Broadband Router firewall includes comprehensive Outbound and Inbound Network Packet Filters.
The firewall does not significantly affect system performance. The packet filter lets you control which
packets are allowed to pass through the router. The Outbound Filter applies to all outbound packets. The
Inbound Filter applies only to packets addressed to a virtual server or DMZ host.

You can select one of the two filtering policies:
• Allow all to pass except those that match the specified rules
• Deny all to pass except those that match the specified rules
