Operation Manual

13 Firewall Settings
The Broadband router provides extensive firewall protection by restricting
connection parameters, thus limiting the risk of hacker attacks, and defending
against a wide array of common Internet attacks. However, for applications that
require unrestricted access to the Internet, you can configure a specific
client/server as a Demilitarized Zone (DMZ).
Port Forwarding
The Port Forwarding allows you to re-direct a particular range of service port
numbers (from the Internet) to a particular LAN IP address. It helps you to host
some servers behind the router NAT firewall.
