If y.yy.yy.131 is your External Interface (attached to your cable modem, (or what ever), you should test from somewhere else, such as your cell phone NOT connected to your wifi, or a shell on some remote machine. I say this because connections "out-the-in-again" are commonly being blocked by some modems these days. In particular I have this problem in Comcast, and have torn more than a few hairs trying to fix it, only to find it was intentional on their part. -- Those who do not understand Unix are condemned to reinvent it, poorly.
