The difficulty that you have described may be due to a firewall. Please remember that if you or your contact is behind a firewall, you cannot have voice conversation or send files. You can only do this with contacts behind the same firewall as you are.

The appropriate ports must be opened in a firewall for file transfer and voice or phone-based chat sessions to work. File transfer uses 6891-6900, and voice uses 6901. Messenger still uses port 1863 to talk to the servers.

Note: For example, port 6901 needs to be opened for both TCP and UDP connections. Opening port 6891 for outgoing TCP only enables file transfer in one (incoming) direction. More ports need to be opened than just 6901 for voice packets to be successfully carried over the network.

枫下家园 / 电脑用户 / 求教,关于IP地址的问题 -yzhp(fitbird); 2002-6-3 {121} (#555497@0)
我使用的是ROGERS的CABLE,和房东SHARE,他买了个一分四的盒子,出来的全是客户端,现在发现用不了MSN通话,请问各位有什么好办法解决?

我以前也有这个问题 -cnyouyou(cnyouyou); 2002-6-3 (#555522@0)
没有任何简单办法,换yahoo messenger -expertune(伪劣砖家); 2002-6-3 (#555532@0)
一般是没办法了, 可以试试让房东把路由器(一分四的盒子)的5004~65535端口都映射到你的IP地址. -zhx(zhx); 2002-6-3 (#555547@0)
请问你说的将5004~65535都映射到我的IP上,如何操作?非常感谢! -yzhp(fitbird); 2002-6-3 (#555561@0)

你还是改用yahoo messeger吧，这个一分四的盒子操作起来还是有点难度的 -chenql26(不懂); 2002-6-3 (#555625@0)

我用yahoo msn,当双方都在网关后面时，也无法语音。 -biosfix(BIOSXP.COM); 2002-6-3 (#555919@0)

那就用netmeeting -chenql26(不懂); 2002-6-3 (#556045@0)

更没戏 -heian(㊣天使-思念ing -19/4); 2002-6-3 (#556052@0)

看router的说明书,如果有web界面的比较好配, 如果只能telnet的就麻烦了 -zhx(zhx); 2002-6-3 (#555684@0)

你说的这个盒子是router吧，你可以将DMZ HOST设成你的内部IP地址，再重起就可以了 -yulp(肥胖儿童); 2002-6-3 (#555735@0)

本人菜鸟一只,这位兄台能详细点吗?我用的是WINXP英文版.万分感谢! -yzhp(fitbird); 2002-6-3 (#555759@0)

我用的也是WINXP英文版，不过这根语音聊天没关系，在我的router手册上有这么一句话： -yulp(肥胖儿童); 2002-6-3 {399} (#555843@0)
DMZ (DeMilitarized Zone) Host is a host without the protection of firewall. It allows a computer to be exposed to unrestricted 2-way communication for Internet games, Video conferencing, Internet telephony and other special applications.

在我的设置窗口advanced->Misc Items中：

IP Address of DMZ Host 192.168.0.* Enable

设成你的IP地址就可以了，然后再充气你的router. Good luck!

能够告诉我你的路由器是什么牌子的？价格是多少？在哪里买的？谢谢， -111111(快乐老家); 2002-6-4 (#557524@0)

D-Link 704, $109, 太古广场 -yulp(肥胖儿童); 2002-6-5 (#558710@0)

这个应该是语音网关的问题 -daynight(这个杀手不太冷); 2002-6-3 {110} (#555818@0)
一般的网关可以传送普通数据，但是语音数据需要特殊的网关，或者在网关上加装H。323协议

说的不对的地方请高手指正

好着急啊!你讲的我都不明白在哪弄,能再详细些吗?十万分感谢 -yzhp(fitbird); 2002-6-3 (#555828@0)

那么是否可以把路由器的防火墙的功能去掉那？去掉了防火墙不就是可以使用MSN和NEtmeeting了？请教。我知道一个可以在防火墙后面使用MSN的软件，但是使用不了NEtmeeting功能。 -111111(快乐老家); 2002-6-4 (#557516@0)

你说的软件是啥?请贴上来嘛! -yzhp(fitbird); 2002-6-5 (#558701@0)

我忘记了，等我想起来的时候告诉你，很好用，专门穿越防火墙的，但是不是很稳定。。 -111111(快乐老家); 2002-6-6 (#562129@0)
