Universal Plug and Play(UPnP) is it needed

Hello,

I have noticed in the Summary tab the problem below.

I would like to now where is the problem.
I have a D-Link DIR-868L and I have activated UPNP.

UPNP

Universal Plug and Play(UPnP) supports peer-to-peer Plug and Play functionality for network devices.
Enable UPnP IGD : activated

Thanks
George
