What are the ports for MSN Messenger version 6 and above?

My firewall software (VisNetic 2.02) set me up with 3 rules for MSN
Messenger: port 1863, range of ports 6891-6900, and port 6901. (all are TCP
rules) This seems not to be enough as firewall log reports outgoing UDP
connections to dst
(one of MSN IPs) port 7001.
