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
	the gateway IP Address.
Hop Count	Enter the maximum number of steps between network nodes
	that data packets will travel. A node is any device on the
	network, such as a computer, print server, or router.
Interface	This interface tells you whether the Destination IP Address is on
	the LAN & Wireless (Ethernet and wireless networks) or the
	WAN (Internet).
Add	Click on Add to add the routing rule to Router’s routing table.
Reset	You can also click ‘Reset’ button to clear all data you entered.
