I've never actually herd of having to open any ports for MSN to function properly. Now, I only use the messenger portion of this so I may not have ever had the need. Without adding any special rules to the firewall or changing the outbound NAT, do you get any error messages in the log? Have you used Wireshark or done any packet inspection on the PC or firewall?
