Connecting via dorms is a common issue that arises here. They're generally firewalled. With LW open, click Tools->Options & go to Bug report & click for an example. In the window that appears scroll down to the part that says: "Recieved incoming this session". If it says ‘True’ then LW has no problem with firewalls, but if 'False' it does have a prob.
See this link for image example. What's your result, True/False?
That's strange, I thought this thread started off in Gnutella Forums > Current Gnutella Client Forums > LimeWire (Cross-platform) > Connection Problems. My mistake! My comments refer to Limewire. My much earlier comments were out of bounds then. Apologies. Except for Morph's aggressive nature.
