Your ISP Starhub are known to shape p2p....
Starhub have caused problems for other people. They're known to shape bandwidth, maybe they're doing some blocking too? Try connecting at different times of day/night. You could also change ports & see if that helps...change LW's listening port to 64049, or something in the range of 49152 - 65535.
