| upnp.delPortMapping Delete a port mapping on the gateway using UPnP | 
| Usage | 
| upnp.delPortMapping <port> | 
| Description | 
| Makes a request to the gateway of the local network using UPnP; the request asks the gateway to delete an entry in its port mapping table. If the gateway accepts the request, it will stop forward packets received on <port>. It's better to check is a gateway has been found using $upnp.isgatewayavailable before using this function. Of course, such a port mapping have to be added using upnp.addportmapping before it can be deleted. |
