I am using the latest version of Azureus. I had configured my D-Link router and Zone alarm to allow specific port and was very happy with little green smilies everywhere..no NAT problem. I had to disable UPnP on Azureus as it was taking too long to map. Yesterday, smilies turned yellow and all of a sudden I have a NAT problem. It says I am firewalled. Have done port stealth test..open. Azureus firewall test..OK. Ports that should be configured and forewarded on my router were still forwarded and working. I tried configuring another port as all above and still says firewalled. Everything else BUT Azureus says everything is fine.Even enabled ports on Windows Firewall even though it is disabled due to Zone Alarm. Have also enabled encryption and checked that my IP address hadn't changed.I even tried to set my router to Static IP,(even though I didn't have to do it before) but then I didn't have an internet connection so I had to put it back. I did a complete un-install of Azureus, then reinstalled with new port configured and finally got a green NAT and green smilies. Left the PC for 10 minutes and it is firewalled again. This is very annoying. There have been no updates to Windows, software etc. What can I do??
