Q:
我使用winroute的連接阜映射實現了內網的MSN messenger和外面對傳文件，但無法語音通信。不知道MSN Messenger的語音連接阜具體是使用哪一段連接阜。還望各路高手指教，在此先謝過啦。
A:
MSn 使用tcp 1863 Netmetting服務連接阜。
微軟的NAT使用指南裡只提供了以下幾種連接阜：
文件傳輸：6891（如果想實現10條並發的文件傳輸連接，您需要開放6891到6900間的所有連接阜）
應用程式和白板共享：1503
遠端協助：3389
唯獨沒有說明msn的語音連接阜？
語音是使用5004到65500的udp動態使用連接阜
對於文件傳輸，需要在伺服器上開啟到連接阜6891到6900的傳入和傳出的TCP連接，這樣
每個MSN Messenger用戶一次最多可以傳輸10個文件。如果只開啟連接阜6891，用戶一次就只能傳輸一個文件。開啟UDP連接5004到65535連接阜將允許適用視音瀕通訊功能。詳細情況可參考

另外，也可以安裝其他視音瀕通訊功能，然後使用MSN Messenger來使用，例如微軟的
Portrait效果就不錯，該軟體支持通過防火牆使用視音瀕通訊服務，而且佔用系統資源
較少，使用簡單，可以單獨使用也可在MSN Messeger中使用，可以通過對方的IP位址或

Microsoft Portrait is a research prototype for mobile video communication. It supports .NET Messenger Service, Session Initiation Protocol and Internet Locator Service on PCs, Pocket PCs and Handheld PCs. It runs on local area networks, dialup networks and even wireless networks with bandwidths as low as 9.6 kilobits/second. Microsoft Portrait delivers portrait-like video if users are in low bandwidths and displays full-color video if users are in broadband. In low bandwidths, portrait video possesses clearer shape, smoother motion, shorter latency and much cheaper computational cost than do conventional video technologies. Microsoft Portrait provides presence notification, chat/voice/video functions almost anytime, anywhere, on any device.
Tips:
* You can place a call either from the buddy list of Microsoft Portrait or from the Action menu of MSN Messenger after you install Microsoft Portrait.
* You can also browse in an ILS server and select a people to call. In order to faciliate Microsoft Portrait users to find each other, we recommend to use ILS server: hello.connectedpc.com together.
* Even if your buddy has not installed Microsoft Portrait, you can still invite him/her from the buddy list of Microsoft Portrait so that he/she can receive a message in an MSN Messenger window, which shows him/her you are inviting him/her and where to download Microsoft Portrait. After your buddy installs Microsoft Portrait, he/she can accept your call.
* If you do not have a camera, you can still see others who do send video, or talk with others in robust voice working at bandwidth as low as 2.4 Kbps.
* You can use any of your PCs, Pocket PCs or Handheld PCs to call.
* You can place a call even behind a firewall.
* If you are a modem dialup user, now you can also conveniently see and talk with others.
* Please adjust the slide of the "Video" button to achieve better visual quality if you select to use black/white video.
* If you have a PC with a camera and a Pocket PC, you can use them to constitute a surveillance system. You can call your PC in your home or office using your Pocket PC anytime on the road.
但是語音是使用5004到65500的udp連接阜，這個範圍你沒有設定映射麼？
映射了6891-6900之後是可以和在不同網關內的pc傳文件 當然有時候還是不行
語音就成問題了 必須有一方是公網ip 映射幾萬個連接阜目前還沒有辦法!
意思是對說如公網對內網不能語音和傳輸有疑問:
在華勤的642r11上的sua選項中有"default ip位址"
就是把所有的斷口都影射到設定的ip上...可以緩解一下沒有upnp的危機...但是只有一個指定的ip可以...區域網路內的其他電腦就不行了....
試過兩個在isa server（不在同一個地方）後的客戶端通過msn進行語音聊天，成功了!!不過兩邊的isa server都配置了h.232傳輸協定。
