I have recently enabled uPnP using Thibor 15c. It works great on a single PC, unlike the Linksys firmware which I could never make work. However, when I enable it on a 2nd PC on my network, the icon shows up for the 2nd PC and it works, but stops working on the 1st PC. When I try a third PC, the uPnP starts working on that one, and quits on the 2nd. It appears that the uPnP will only work on a single PC at a time. I am running Shareaza and have downloaded the latest version which uses uPnP, and I would like to make uPnP work on all of my PCs on the network at the same time. Does anyone have any experience with Thibor 15c using uPnP on mutliple PCs? Thanks for any help.
