試試看安裝DirectX8.1吧,M$N Messenger的線上指引有說明NAT所需要的環境,
DirectX 8.1是其中一項(好像是UPnP需要新的DirectPlay支援)。
Linksys台灣並沒鋪貨。向Linksys求助比較快......
(Linksys的確是早期少數支援UPnP讓M$N過NAT的分享器廠商之一,
用DMZ是最糟的方式......這也是一般分享器能讓M$N過NAT的設定方法。
用DMZ當然會有實體IP數量的限制。這也是chih_haohung最不想用的方法;)
chih_haohung希望的還是原本透過UPnP所有NAT後的M$N免設定
直接要求對方交談的方法吧?)
以下是Linksys 公司回給我的信
所有方法我都試過了 都沒用
我看我放棄算了..........
我的問題是可以在MSN Messenger建立語音連線
但是只可以對方邀請我 不能我邀請對方
我沒有加裝任何防火牆軟體
一般來說 MSN Messeger 語音交談
分兩種情形
不能建立
可以建立 如果可以建立的話 不可能再分 只能誰邀請誰的區分
偏偏我就遇到這種情形
Dear Valued Linksys Customer,
Thank you for contacting Linksys Customer Support.
That is indeed an odd behavior of the router.
You might want to hard-reset the router. You can do this by pressing the reset button for at least "30" secs. You need to have a back-up copy of your previous configuration because this will erase all your current settings. If this won't work, try the possible work around:
-Try to hold reset with power off.
-If this won't work, try to hold reset while plugging in.
-If neither of the steps work, try to power on and hold reset. Then pull the plug. Power on again.
And then, try to configure the router for your internet connection. See if there is any change in the behaviour of the router.
If still, there is no change, you might want to try opening the following port:
Forward ports 6891-6900 to enable File send
Forward port 6901 to enable voice communications
IN TCP 6891 - 6900
IN TCP 1863
IN UDP 1863
IN UDP 5190
IN UDP 6901
IN TCP 6901
Please take note that static ip address must be set to your pc to make port forwarding work. If you’ve set your router as a dhcp server, it would be advisable to ***ign a static ip address below the ip range of your dhcp. For example, the starting dhcp ip address of your router is 192.168.1.1. Then, it would be advisable to use the ip range of 192.168.1.2 – 192.168.1.99.
Below are steps on how to do Port Forwarding;
1. Open the web browser and type the router's IP Address 192.168.1.1.
2. Enter the Username and P***word by default leave username blank and type admin for the p***word.
3. Click the Advanced Tab, then Forwarding Page.
4. On the Customized Application, type in the name of your application.
5. In the Ext. Port. enter the port number.
5. On the Protocol click on the TCP/UDP, depending on what protocol is the internet application is using.
6. On the IP Address, enter the specific IP address that you are using.
7. Click Apply then Continue.
In order for your router to successfully forward ports, the SPI feature of the router should be disabled. This feature checks the
state of a packet to verify that the destination IP address matches the source IP of the original request. SPI opens the ports as needed
SPI as "Dynamic Port Forwarding".
Kindly enable the multicast p*** through feature of the router. Multicast p*** through is enabled so that the router will allow
multiple transmissions to p*** to a specific recipients at the same time.
1. Enter your router's web based utility.
2. Click on the Filters tab.
3. Enable MultiCast P*** Through.
4. Click on Apply.
You might want to adjust the MTU setting of your router. MTU also known as ,"Maximum Transmissible Unit", is the maximum size a packet can be in a network.
This is how MTU works.
When a TCP connection is made a SYN/SYN-ACK exchange is the first thing done. The client sends the SYN and the server replies with the SYN-ACK. In these messages the MTUs are included so each can send packets of the right size to the other end. Actually MSS (Maximum Segment Size) is sent but for TCPIP that's a value that excludes TCPIP headers and is always 40 less (MTU=1492 is MSS=1452).
On outbound connections the LinkSys will actually change this MSS value on-the-fly to be what the setting is. You could say the LinkSys "enforces" the MTU that is set. Even if the PC sends MTU=1500 the LinkSys changes it in the SYN packet - this is how the other end *really* sees 1492 (if that is what the LinkSys is set to). This is desirable since you can run your LAN at 1500 MTU yet go out to the net at 1492 automatically!
But server connections don't seem to get this help. Not only that, the ISP equipment and/or the DSL modem lets these SYNs come in saying they're 1500 MTU! The LinkSys does no alteration (it's INbound not OUTbound). The PC is happy (it's 1500 MTU after all) so these 2 ends try 1500 MTU.... BUT THAT DOESN'T WORK ON PPPoE!
The result is large packets (above 1492 MTU) will not transfer well at all and usually just hangs the TCP stack.
One funny thing you WILL see... small data transfers of, for example, small directories or small html files DO get through OK. This is because the packet size never reaches a fatal value.
Here are some guidelines in adjusting the MTU setting:
Steps
1. Open the web browser and type the router’s IP Address.
2. Enter the Username and P***word.
3. Click the Advanced Tab, then Filter Page.
4. Enable MTU and enter your desired size.
5. Click Apply then Continue.
Or use this shortcut http://192.168.1.1/Filters.htm .
Changing the MTU setting allows you to set an MTU value in your router and should correct problems regarding web browsing, downloading, email sending/receiving, and FTP. Try to ***ign values such as 1382 or 1400 or 1450 or 1492 and see which has the most stable connection.
Lastly, make sure that block wan request is disabled. Block WAN Request can prevent your network from being "pinged," or detected, by
other Internet users. The Block WAN Request feature also reinforces your network security by hiding your network ports. Both functions of
the Block WAN Request feature make it more difficult for outside users to work their way into your network. Kindly see the steps in disabling
the block wan request.
Steps :
1. Open the web browser and type the router's IP Address.
2. Enter the Username and P***word.
3. Click Advanced Tab. then Filters page.
4. Under the Block WAN IP Address option, click disable.
5. Click Apply then Continue.
