Hi,

A while ago I was struggling hard to find a workaround for having
voice conversations via Windows Messenger v5.0.0468 and to no avail.
I'm connected to the Internet via an Alcatel SpeedTouch Pro ADSL
Modem/Router which is connected to my 2 WinXP PCs home network through
a switch. File Transfer was working on and off depending on
recipient's setup (could never really figure out what made the
difference though). Last night a friend recommended trying the new MSN
Messenger v6.1.0203 as a fix for the FT problems. Having tried MSN
v6.0 in the past with no better results than Windows Messenger, I was
quite reluctant to try it out again but was finally persuaded and
guess what? Not only file transfers work flawlessly even if its
another NATted network on the other end (using the same version of MSN
Messenger) even voice, which was always said to not withstand a chance
penetrating a non UPnP router is working too. After reading MS's
"Windows Messenger in Windows XP: Working With Firewalls and Network
Address Translation Devices" article at:

http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechnol/winxppro/evaluate/worki01.asp

it just puzzles me even more how come all this got solved with me not
having to do anything but upgrading the SW? (no router configuration
changes made whatsoever) and another thing - can anybody tell (a) how
does it do it? (workaround the NAT issue that is) (b) Are these
features going to find their way into future releases of Windows
Messenger?

TIA.

Rany.
