I downloaded & installed azureus.when i start it the configuration wizard runs and whatever port i give,it gives a nat error.The downloads are working but really slow.Also i went to their troubleshooting page & their they something about portforwarding which i cannot understand.I have disacled all firewalls.I use an airtel gprs connection.they also say something about router.how can i find my router?Actually what is all this?What should i do to remove this nat error.
