LimeWire Detected A Firewall HELP!!!!!

[c.brenda35]

I have just had dsl installed and there is a router hooked up to my desktop computer so that my laptop can be wireless and run. I have limewire pro on both computers .. desktop is a vista and the laptop is xp dell d-600 .. Now when I was on dial up I never had a brick wall infront of the globe that reads limewire has detected a firewall.. Now that I have dsl and a router I have that little red brick wall on that globe. I still connect to limewire and can still download dont seem to be much a problem with the firewall thing .. But I was wondering how I can get rid of that brickwall?? And without a firewall being detected would my downloads be even better then now? How do I even go about getting rid of that brick wall? Can someone out there please give me step by step of what to do?? I really appreciate this .. Thanks Brenda
