And my 51413 port is open on my router, but transmission show "port is closed".
Upnp is turn on on the router.

And is the past, the add on works perfectly (10 days ago). I don't change any thing. I don't unterstand.
Is there a LOG file for Transmission 2.84 on the Nas Readynas Duo ? How and where I can find it ?
