How Any Ip Works - ZyXEL Communications Prestige 660W Series User Manual

Prestige 660W/HW Series User's Guide
With the Any IP feature and NAT enabled, the Prestige allows a computer to access the Internet without
changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses
of the computer and the Prestige are not in the same subnet. Whether a computer is set to use a dynamic or
static (fixed) IP address, you can simply connect the computer to the Prestige and access the Internet.
The following figure depicts a scenario where a computer is set to use a static private IP address in the
corporate environment. In a residential house where a Prestige is installed, you can still use the computer to
access the Internet without changing the network settings, even when the IP addresses of the computer and
the Prestige are not in the same subnet.
The Any IP feature does not apply to a computer using either a dynamic IP address or a static IP address that
is in the same subnet as the Prestige's IP address.
You must enable NAT/SUA to use the Any IP feature on the Prestige.

5.7.1 How Any IP Works

Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a
physical machine address, also known as a Media Access Control or MAC address, on the local area
network. IP routing table is defined on IP Ethernet devices (the Prestige) to decide which hop to use, to help
forward data along to its specified destination.
The following lists out the steps taken, when a computer tries to access the Internet for the first time through
the Prestige.
