if your Firewall/&/antivirus in OS (vista or XP) is off.... your Limeware detect again a Firewall
... this is normal
I explain, ithis means that you must add a Port in your LAN (routeur) like Emule or auther P2P... to open the door for your Limewire!
1 - you can get this number "port" in your setup option Lime! in tag "Advance" -> "Firewall" : your number is in "port local"
2 - in your "routeur" -> "Server Lan" you must add a opening on your IP with this number.
3 - after this you must restart only your Limewire and your "firewall".....has disappears
your connection increase to 150% or more - you'll see it to your eyes
sorry at all, for my poor english
