Comment:

 If you can get the xml sent and received by both sides during the file
 transfer attempt we can begin to figure out if your friend is getting
 anything at all and if there is anything you are getting back that we can
 use as a status/error indicator. As to whether you need a proxy, I believe
 you will need a proxy whenever the sender of the file does not have a
 publicly reachable IP address (but my knowledge of the XMPP file transfer
 mechanism has always been spotty).
