Correct. According to


and MS knowledgebase article Q316660, Messenger's voice feature is
apparently NAT incompatible...

"Currently, certain extended features of MSN Messenger, such as voice
conversations and file transfer, might not work behind Internet Connection
Sharing applications and hardware (often called NATs). Basic functionality
such as signing in, instant messaging, and checking e-mail should not be
affected at all."

Note, I don't use Messenger myself, I just did a quick search at
