I know this kind of thing has been covered in many other posts, but please try and help me. I keep getting a NAT error in Azureus. I manually opened port 52525 from the router settings (Advanced > Virtual Server) and even added it in the exceptions list in Windows firewall. Still the NAT test fails. If you aren't getting this error in Azureus, which port are you using and what settings did you have to modify?
