Dear all, I would be appreciated if someone can point me out how to fix the NAT error when I try to d/l stuffs using Utorrent. I have read and tried (e.g. www.portforward.com) everythings on the internet but still can't open the port (65535) I use in utorrent. I am using Windows XP SP2, Netgear DG834 modem/router. What I did: Windows: - Firewall > Exceptions > Allow 65535 TCP/UDP - Firewall > Exceptions > Allow utorrent - Temporaily turn off firewall software Router: - Allow port 65535 TCP and UDP - 65535 port forwarded to 192.168.0.3 (from ipconfig, I have a static IP) - UPnP Off - Log Off Utorrent: - Use 65535 - UPnP Off I also tried UPnP On in the router and utorrent, but still got NAT error. Also tried to open different port, still the same. Tested 65535 port (from www.grc.com and utorrent itself) and said stealth and NAT error, so apparently the port is not open even I port forwarded. Any adavice is appreciated.
