Thanks for the quick reply. I re-did the configuration of the firewall in Norton 360 after installing it last week. So LW is in the list with programs which have always access to the internet, but LW still gives the message that it is behind a firewall. I had a look in the faq and change the listingport to port 35000 but still no change. By the way I tried the testlink to and this is working. Is there anyone using Norton Security 360 and has no problems. What are your settings?
