3.1.3 NAT / Static Routing
Network address translations (NAT) shares a single public IP address to multiple computers. All computers must be assigned a valid public IP address to be able to get connected to Internet, but Internet service providers provide very few public IP addresses to each user based on service plans, usually 1 for each household. Therefore, it’s necessary to use NAT technology to share a single Internet IP address to multiple computers on a same local network, so everyone can get connected to Internet.
The NAT function is enabled by default; to disable it, you need to enable Static Routing by checking the “Enable Static Routing” box. Do not disable NAT unless you have professional knowledge on routing.
Please follow the following instructions to set Static Routing parameters:
Parameter | Description |
Enable Static Routing | Check/uncheck to disable/enable the NAT function. |
Destination LAN IP | Enter the IP Address of the destination LAN. |
Subnet Mask | Enter the Subnet Mask of the destination LAN. |
Default Gateway | This is the gateway IP Address where packets are sent. Input |

| network, such as a computer, print server, or router. |
