[X4U] MSN Instant Messenger Ports

[John Newhoff]

 From an MSN tech note:


>  To enable voice communications, make sure that outgoing TCP 
>connections from port 6901 are enabled. Also enable UDP packets 
>where either the source or the destination port is 6901.
>
>  To enable file transfers, enable both incoming and outgoing TCP 
>connections to the 6891-6900 range of TCP ports. This allows each 
>sender to perform up to 10 simultaneous file transfers. Note that if 
>only TCP port 6891 is open, users are only able to perform one file 
>transfer at a time.
>
>  To enable messaging, enable outgoing TCP connections to TCP port 1863.


Thanks,
John
