1. Make sure ur using the latest version - 2.5.0.02. Use any port between 49152 - 65535. Forward both TCP as well as UDP packets.3. Turn off the UPnP plugin (Tools>Options>Plugins)4. Make sure the NAT status light next to DHT is green (when downloading a well seeded torrent). Or use the NAT Checker under Tools.5. Now try downloading a public torrent. If it still says firewalled, add the DHT Scraper plugin for Azureus and set the port u have forwarded in its Options. (Plugins>Installation Wizard>By List...wait a while for the list to load, select DHT Scraper)EDIT: Forgot to mention this. Try to reseed the DDB database:1. Go to Tool>Options>Plugins>Distributed DB2. Hit the reseed button and wait. If the user goes up and the DHT light turns green, then it's fixed.3. If not, then you can specify the IP and port of any DDB node (Azureus peer) or dht.aelitis.com and 68814. Hit the reseed button again and wait.If nothin works, try µTorrent 1.6
