应该可以,但要设置你的router,如何做,一两句话说不清楚,参考:
What do I do if I have a firewall?
No matter what kind of firewall you have, you will need to configure it to allow the computers within it to open outgoing TCP sockets to allow your network users to use MSN Messenger Service. Computers on the internal local area network will need access to the Domain Name System (DNS) servers to resolve the names of external hosts such as microsoft.hotmail.com.

• To enable the use of MSN Messenger Service: Open outgoing TCP Port 1863, and configure it so that sockets on this port are open for extended periods of time.
