@Firon Yes UPnP is enabled, i'm not completely stupid My router is a Billion 7402VGP, and 1.6 works fine on XP SP2 with the current router config. Based on previous UPnP threads, i'm not sure we should clutter this Announcement post with UPnP bug reports, my only real suggestion at this point is for the current developers to add similar debug information in the log, as ludd had done on previous 1.5/1.6 builds, such as the location of the XML UPnP schema that the router is reporting, etc...
