 The Gateway supports automatic device discovery and port configuration for UPnP-enabled devices.
For more information, see “7.1.1 UPnP”
.
 The Gateway allows you to assign a port to a device. For more information, see “7.1.2 Port forwarding”.

7.1.1. UPnP
UPnP is designed to automate the installation and configuration of a (small) network as much as possible. This
means that UPnP-capable devices can join and leave a network without any effort from a network
administrator.
Supported operating systems
 Windows 10
 Windows 8
UPnP and the Gateway
UPnP offers you the following functions:
 You do not have to manually create port mappings to run services on a computer. The automatic port
configuration mechanism for UPnP-enabled applications will do this for you. If the application is UPnP-
enabled, UPnP will create these entries automatically.
 You can access the Admin Tool without having to remember the address of the Gateway.
Enabling UPnP on the Gateway

your Gateway (either wired or wirelessly). For more information, see “Accessing the Admin Tool”
.
