Posted this bug on Transmission's bug tracker and they referred me here...

Quote:
I've noticed that after waking from sleep after a certain time, the UPnP lease on my router seems to time out and the port check tool reports it as closed. Even after randomizing the port, it still reports back as closed. The only way to get the application to map the port properly is to uncheck and then recheck the "Automatically Map Port" checkbox or restart the application.


Is this miniupnp's fault or Transmission's fault, I wonder?

I suppose that the router remove the port mapping after a certain time.
Well it can happen, it is router's fault.

But apparently, Transmission doesn't react well to that, it looks like it still think the mapping is there, so it doesn't work.
Transmission should use miniupnpc API to check the mapping, and add it again if needed.

IF port appears to be "closed" :
call UPNP_GetSpecificPortMappingEntry()
IF return code is 704 "NoSuchEntry"
THEN call UPNP_AddPortMapping() again

if the mapping is with another internalclient/port, well the mapping was "stolen", the safe thing to do would be to change port (external port)
