In the connection status tab of MSN Messenger, it says:
Your are directly connected to ".NET Messenger Service" as well as it says, "You are connected to the Internet through an unknown NAT. (administrator)".
I do have uPnP on my router, but it doesn't seem to be compatible with MSN
I did forward all ports (6891-6901), but, I cannot check "Allow me to connect directly to my contacts when sending messages". Also, incoming file-transfers are slow.
I take it here is something more I must do / setup, but what?
