I can access my NAS locally without any issues with UPNP disabled and the http/https port closed on my router
I know that the port used are different, and I'm not talking about the UPnP discovery service in TOS. What I am saying is that every service in TOS is using UPnP to open the ports to remote connections in the router. Which is a security issue.
