Enable/disable NAT (Network Address Translation). The default is Enable. 

• 

Your LAN can use one set of IP addresses for internal traffic and a second set of 
addresses for external traffic. In other words, the router with NAT does the simple IP 
routing between the LAN interface and the WAN interface.  

• 

Your internal addresses are shielded from the public Internet.  

• 

The router functions without performing any address translation on the packets passing 

through it.  

• 

Masquerading of packets originating from the LAN is disabled.  

• 

Address translation of packets arriving from the WAN is also disabled. 

• 

Any DNAT Configuration previously setup in the DNAT Configuration screen is disabled. 

This prevents the user from adding any DNAT rules, which if allowed would defeat the 
purpose of enabling Routing.  

 For routing to take effect, the configuration must be saved after enabling it. It won’t be 

effective on the fly at runtime.
