7.8.1 | Network Filters
The VPN 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.
