How does the UPnP function of the Thunderbolt be blocked?

What is UPnP functionality

The English full name of UPnP is universal Plug and play, the Universal plug-and-match protocol, which is the architecture of Peer-to-peer network connectivity for computers and intelligent electrical devices. The intranet address and network address conversion is based on this protocol, so long as our routers support UPnP, and we use the XP operating system to support this protocol, then we can improve point-to-point transmission speed.

What if the UPnP feature is blocked?

1, is generally the user set the router's UPnP function shutdown situation. Go to the router to set up UPnP to enter 192.168.1.1/192.168.0.1 in the browser address bar, and then return. The general default account is admin, password is also admin. Then click on the UPnP settings in the virtual server to hook and save them on the enabled item. Finally restart the Thunder. Now check to see if the problem is resolved. If the router does not have UPnP, it can only help you with port mapping on the router.

2, check some thunder of the UPN function is open, if not open, it can be opened. As shown in the figure:
