a basic question abot UPnP

[lyapounov]

Hi all
I have a blockage regarding UPnP, and more specifically about allowing UPnP or not on the router.

What I don't get is what is the use of turning UPnP on on the router ? I have read about the security issue, so I turned it off.

But turning UPnP off does not prevent minimserver to function normally. Therefore my question: what is the point of turning it on ?

Thx !
