IPnP
19.1 IPnP 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 Zyxel Device 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 Zyxel Device’s LAN IP address can connect to the Zyxel Device or access the
Internet through the Zyxel Device.
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 Zyxel Device'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 Zyxel Device 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 Zyxel Device are not in the same subnet.
