Hi 1337_,
You have to give a bit more info
Is your connection ok? Is it just the firewall icon showing or are you getting an error msg?
Can you download? Can people upload from you? Are you using a router that may be causing problems?
Give a description of your set-up:
OS
Any firewalls running (including Win firewall)
Modem/router brand & model number
LW & Java version
Connection type (dial-up, cable/dsl etc)
Where are you connecting from ( home, work etc)

Be patient & wait for someone to reply. In the meantime, you could do a search (top right, between faq and home) for 'firewall' or something similar. Also, have a look at the various stickies in different sections of the forum. You might find some answers there
