Use the “Virtual Computer” option to maintain the privacy and security of the local network.
Virtual Computer enables you to use the original NAT feature, and allows you to setup the one-

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.
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
