    i have the same problem its really annoying someone plzzz help lan settings dont work xxx

  • xxLiliumLust May 25, 2009

    Yeah, I have the same problem.
    I tried the thing the one guy said to do (apprentice) or
    whatever, and it didn't even work.

    When I sign in, it ALWAYS trouble shoots.
    And it always ends up being a problem with the key ports.
    I can sign into my older version of msn,
    but I can't sign into the latest version of msn I downloaded
    about a few months ago.

    And I really want to get onto the newer version instead.
    But it won't stop trouble shooting, and when I hit "repair"
    it doesn't really even do anything. :/

Try connecting to this URL:

If you can connect, then there are several different things that could be wrong:

I use XP. What worked for me was

Start > Run
netsh interface tcp set global autotuninglevel=disabled

Restart messenger.

If that doesn't work, try:

Start > Run
regsvr32 Softpub.dll Mssip32.dll Initpki.dll

Wait for all three boxes to popup confirmation.

If that doesn't work:

Start > Run


Internet Time Tab

Update Now Button.

After sync, try again.

I hope that fixes everyone's problems. I've never had this problem until I installed the latest Messenger.

When i connect to xbobx live it says my NAT is not open and onlone gameplay is slow. how do i fix?

NAT is network address translation, this is what allows multiple device on your home network communication through one portal to the internet and still retain individual data streams.
To resolve this issue you need to enable uPnP on your router/wireless router. This depends on your router but you will need to login in to the configuration page of your router, usually by browsing on your local network to and logging in. Once logged in to the router you will need to click around to find the UPnP option and enable it. This may restart your router but after that fire up XBOX live and try to connect, you issue should be resolved.

Apparently i need to open ports for xbox live any help?

How to Open ports on your router for xbox live. (wrong forum) If your NAT (Network Adress Translation) is "moderate" or "strict" you will only be able to play with people who have a open NAT. You can find out what you are by going to "System" on the Xbox 360 dashboard, click on "Network Settings" and test your connection. Upon passing all tests it will tell you your NAT status at the bottom.

If your using a router or other gateway device you need to port forward certain ports.

Open up your start menu, click on "Run..." type 'Command' once the command window comes up type, 'ipconfig /all' take note of your "Default gateway", you might need to scroll down.

Open up a browser window. Internet Explorer, Firefox, Opera...

Type your default gateway and it should access your router.

You may have to enter your username and password, if you havent changed it, it should still be default, 'admin' for both username and password, sometimes 'Username' and 'Password' if you cant figure it out contact the maker.

First off make sure UPnP (Universal plug and play)

Now, this varies for all routers, but usually its under Advanced Settings or something along those lines, some even have a port forward tab, others are called application sharing or using.

Then open ports, or open application ports or assign application/game.

The following ports must be opened...

UDP 88
UDP 3074
TCP 3074


Any troubles email me.

If your default gateway doesnt work, or you cant get into your router go to and look up your router.

Msn key ports will not fix!

Dear Friend,
First of all, always check the status of your web browser before signing in to windows hotmail messenger.That means that if you try to sing in, be sure that work offline mode in your browser is not checked.Secondly, have you run the MSN MESSENGER port configuration?Third and most important, have you opened the ports in your firewall?
Here is the list of thee ports that MSN Messenger uses:
1366 MSN Messenger
1367 MSN Messenger
1838 : TCP MSN Messenger (Gamevoice)
1863 : TCP/UDP MSN Messenger primary (incoming)
5190 : UDP MSN Messenger (incoming)
6891 : TCP MSN Messenger Filetransfer (incoming) - ports 6891 - 6900, one port per file transfer
6901 : TCP/UDP MSN Messenger Voice Telephony (incoming)

5004 : UDP MSN Messenger, ports 5004-65535. Used for AUDIO and VIDEO. Caution: securty risc! Do not open ALL these ports!
5004 : UDP MSN messenger (dynamically uses a port in this range 5004 – 65535 - requires uPNP in your NAT router and/or firewall). Used for AUDIO and VIDEO. See Microsoft website for details....

Good Luck!

I need to open some ports on my belkin UDP88,UDP3074,TCP3074

First of all I would check and see if you router is on the compatibility list from Microsoft. If it is there is a good chance it should work just by enabling UPnP (Universal Plug and Play) is enabled on the router.

If this is not an option, or you router is not on the list you may have to enable the port forwards, they are sometimes listed as NAT or Network Address Translations on the router.

You may have to forward all of these ports:

  • UDP 88
  • UDP 3074
  • TCP 3074
  • UDP 53
  • TCP 53
Page 64 of you manual will tell you how to do this. Belkin calls it "Virtual Servers" and it will be found under "Firewall" on the menu tree on the left of the web gui.

Once you're there it should be fairly self explanatory.

Hope to see you online soon!

My wireless XBOX 360 says ''not connected'' when I test XBOX LIVE

in this case you need to do a port forwarding,which is something like opening the specific ports on router so that xbox will communicate with internet
for that we need to know the ip address of xbox and port numbers for microsoft for knowing the port numbers and their range,so we can do a port forwarding on your router

Router will not allow me to play onling games through xbox 360

If the problem has something to do with NAT firewall in your router, then you may need to open certain application ports for your XBOX in the router. You may check this link from Microsoft that talks about NAT firewall and XBOX live.

Hope this helps!
