II-2 LAN
Local Area Network (LAN) is a group of subnets regulated and ruled by the router.
The most generic function of Vigor router is NAT. It creates a private subnet of your own. As
mentioned previously, the router will talk to other public hosts on the Internet by using
public IP address and talking to local hosts by using its private IP address. What NAT does is
to translate the packets from public IP address to private IP address to forward the right
packets to the right host and vice versa. Besides, Vigor router has a built-in DHCP server
that assigns private IP address to each local host. See the following diagram for a briefly
understanding.
