Search the word Dorm or dormitory or school on the forum. Dorms & schools have a habit of blocking p2p use. You can try force ip: Force IP instructions & sample image using port 6346 but there's no guarantees.

I suppose you could try a Proxy connection. I know nothing about them so can't direct you sorry.

Yu could try other port no.'s for lw. Else ask the network staff if they can help you.
