Here are several things to try:
  1. On the off chance that you have FTP Proxy or FTP through IP/translation and CPAN is using Net::FTP set FTP_PASSIVE=1 environment variable.
  2. If you can do http downloads through your browser then you could us wget to download to your .cpan/build directory but then if this works I don't see why LWP doesn't work.
Bit of a shot the dark but might help.
