I can get MSN Messenger - Application Sharing to work on my home network, where two laptops are connected to my wireless router.  I enabled UPnP on my router to get it to work.  At work, same thing, I can do application sharing with coworkers who are all connected to my work router, which also has UPnP enabled.  When I try to do application sharing from my home network with someone on my work network, I get a SIP timeout error.  What do I need to modify to get this to work?? Thanks!
