小弟用Win2000 Server內的ICS提供家中兩台電腦上網
想使用MSN Messenger和麥克風和遠方的友人聊天

根據我查詢到的資料，這樣的組合會出問題，而且是語音和傳檔都會有問題。

我想問的是，難道就沒有解決辦法嗎？

先謝謝各位的回答...

　　MSN Messenger Service Cannot Perform File Transfers or Make Voice Connections Through NAT (http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q278887)，看看文中提供的解決辦法，雖然不一定有用，但值得一試。

文中提到:
To work around this problem, install Proxy server, create a Winsock protocol definition for TCP ports, and then install the Winsock proxy client on the computers that use the proxy server

小弟英文程度不好，但還看的出，需建立Proxy機制...
Win2000 Server似乎沒有內建的Proxy可用......吧？
那我應該....?

再來是:
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.

NOTE: On the Connections tab in the MSN Messenger Options dialog box, make sure that the I use a Proxy Server check box is not selected.

也就是開啟TCP Ports 6901 和 6891-6900
這類似分享器的Port Mapping吧，這我還有點懂耶..

所以我知道該做的就這兩項了，大哥您說對嗎？
