However, my internet works but there seem to have no incoming connections to utorrent which indicate by the small yellow triangle at the bottom. Is there a way where i can configurate inorder to receive connections, or does it mean i nid to change any hardware, inaddition for my case is portforward still require? Any help is appreciated, THX
