Hi.
Since nobody was interested in this, and i do have the same problem (dropping packets), i did investigate this, and make it work. It took me 2 days. I guess, that is to much for big corporation, is it? 
Anyhow, to avoid copy/paste, look at http://sourceforge.net/mailarchive/message.php?msg_id=30922613 for explanation, and http://sourceforge.net/mailarchive/message.php?msg_id=30922661 for resolution.
Please try it, and report back. It does work for me (tm).
