Comment 4 for bug 230973

Well it's somewhat difficult to blame router or PC if it works for all the applications except DC.. and even for DC it used to work, till about a week ago, when it just stopped working. My router is running latest Tomato, which definitely has working upnp.

I've used Intel's UPnP debugging tools. One of them has upnp packet sniffer. Whenever a upnp application tries to forward ports, it lists all the packets being sent. For DC it doesnt show anything, as if not a single packed would be going out..
