I reinstalled utorrent recently. I opened ports on my modem (port 6881 - 13081-53819, TCP and UDP), in order to change and see if something changed. the problem is that during testing on utorrent port opening, he told me that my ports are not open. Better, in the case of the port 6881, a sudden he tells me it is ok, and 1 hour later, it told me that the port is not open. Someone has an idea of where this problem may be? I hope to clear enough, just ask me if you want to more information on this thank you in advance!
