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:
