23.1 Overview

IP Plug and Play (IPnP) allows a computer to access the Internet without changing the network
settings (such as IP address and subnet mask) of the computer, even when the IP addresses of the
computer and the UAG are not in the same subnet.
When you disable the IPnP feature, only computers with dynamic IP addresses or static IP
addresses in the same subnet as the UAG's LAN IP address can connect to the UAG or access the
Internet through the UAG.
The IPnP 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 UAG's IP address.
Note: You must enable NAT to use the IPnP feature.
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 UAG 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 UAG are not in the same subnet.
