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.
Type the destination port end for the destination IP. If this
field is blank, it means that all the destination ports will be
passed through the WAN interface.
