I recently installed Avast 4.7 for Win XP 64. Now my Torrent App is having NAT issues despite the fact that the port is enabled on bot my router and firewall. I can’t find any settings that would sause this behaviour, so anyone that has a clue, please let me know.
First make sure that you don’t have UPnP enables on your torrent client. Universal Plug and Play (UPnP) allows the automatic mapping of ports on UPnP enabled routers. I know that I had a problem with my NAT untill I dissabled it. If you can’t get it to work you may want to try DHT Scraper.
