Configuring Security Features 
The Router provides broad security measures against unwanted users. Security also allows for the 
configuration of the firewall, administrator password, (NAT) Network Address Translation, and DMZ 
(Demilitarized Zone) configuration. The security options are listed below. 
Manage administrator login name and password.  
Configure network-based date and time functionality. An accurate date and time is of use 
when logging system and firewall events, and is a requirement for some firewall 
functionality (e.g., ICSA-compliant firewall operation).  
Configure and control IP addressing on the Local Area Network through either NAT or 
NAPT.  
Configure and control the internal firewall. Many of these features require a thorough 
understanding of networking principles and firewall operations. The firewall options are 
listed below.
