Salut Fungi14, I've made a request to LW team (there is a 4.1/4.2 request thread in the forums -you can do a search about it-) so they put a little light in the gui indicating wether you are firewalled or not. We'll see if it will be included in 4.1 betas. At least you are in the 30% unfirewalled nodes, 70% are sadly firewalled and this slows download speeds a lot
Ciao
