NAT-type strict. Help me. I've done everything.

[gustavlufsen]

Hi,

Router+modem Thomson TG787.

Ports open:
* TCP 80
* UDP 88
* UDP 3074
* TCP 3074
* UDP 53
* TCP 53
* UDP 1500
* UDP 3005

UDP 3478
UDP 3479
UDP 3658
UDP 1200
UDP 27000
TCP 27030

* UPnP activated/on

This is checked with a portchecker, so Im sure they are open.
cmd -> ipconfig -> my IP adress 192.168.1.65
Portfarwording is correctly done and portchecker says they are open!
Printscreen to show you:
http://data.fuskbugg.se/skalman01/portchecker11.JPG

DMZ can't be done on Telia Thomson TG787 from my router settings. (Yes, Im admin login)
One computor in the network.

New installed Windows XP on my computor.
Got all windows updates (netframe etc..)
- Windows firewall OFF
- No installed firewalls/anti-virus

-----------------------------------------------------------------

I want my NAT-type to be opened.
What's going on, whats the problem?

Required Ports for Modern Warfare 2
In addition to the required ports for Steam, Modern Warfare 2 requires the following ports for multiplayer:

UDP 1500 (outbound)
UDP 3005 (outbound)
UDP 3101 (outbound)
UDP 28960


https://support.steampowered.com/kb_article.php?ref=3991-EOAV-1596

Are the ports at the right places? (Like Filter and not applications (or is that the other way around))

Your router has failed you. I can't really offer anything else besides cold starting all your equipment in a proper fashion in hopes that your router will work after that.

[Loeder]

PM me if you succeed and tell me how you got it to work, I typed you a whole solution and then start reading your OP and found out you done all that... lmao.

-----------

I got it too work by enabling UpNp in my router/modem along with opening the right ports and then turning off my software firewall on your OS (once you have OPEN NAT in game you can experiment with turning on your firewall.

note: EVEN WHEN YOU ASSIGN FULL ACCESS TO A PROGRAM IN YOUR SOFTWARE FIREWALL MOST OF THEM WILL STILL NOT WORK WITH IW.NET SAME GOES FOR GTAIV AND/OR WINDOWSLIVE FOR THAT MATTER.

I got OPEN NAT in game in combination with a zonealarm firewall with medium security on... but even that sometimes fails and i have to turn the firewall on and off.

[gustavlufsen]

Ehm. Im already using that portchecker to check my ports ;)
As I wrote in the first post, even with a screenpic of the checker says its open!

I can play too.
But, cant join groups (depends on who the creator are).
And I cant host for everyone I assume.

Your router has failed you. I can't really offer anything else besides cold starting all your equipment in a proper fashion in hopes that your router will work after that.

Already done that. Restarted the computor/router+modem.
Restarted the router/modem thru the admin login and by plugging it on/off.

[Freyar]

Is XP able to detect your router?

There's a component (Under Add/Remove Programs, Components, Network [Something or other] (details) that helps XP find and ask for UPnP ports.

GFWL failed UPnP tests until that component was installed.

[gustavlufsen]

No, but I can pm you that I've already done that.

- UPnP activ/on
- No firewall softwares/Windows firewall
- Ports open
- Restarted everything.

Did you close the program then start the game? The program may be using that port if it's still running.

Disable your windows firewall and any other firewall. If there's still an issue do the following:

Start > Run > msconfig
Services > Check option "Hide all Microsoft Services" > Click Disable All
Startup > Click Disable All
Restart and then try playing the game

[gustavlufsen]

Is XP able to detect your router?

Good question,

How do I know if XP detects the router?

In the router login it finds my computor.
And the portchecker says ports are opened to my IP adress.

So, its detected right?

/G

[Freyar]

If you have the component up and running, going to "Network Places" should show your router if discovery is turned on by the router. (Don't ask me how, I have no idea what the interface is for yours, it's partially why I suggest Tomato on Linksys routers.)

[gustavlufsen]

Did you close the program then start the game? The program may be using that port if it's still running.


Ofcourse. Played and rebooted my comp 10 times.
msconfig in run etc..

I have swedish, and nothing reminds me of the options you said.
Please, if you have time. Add print screen.

I think you mean run with the basic drivers & services options. But is that really that smart?
I want my computor to work normaly even if im not playing.

I think he means: (and this is translated from dutch)

Start->Networklocations->window pops-up-> on the leftside you see a row of clickable icons/options, one of them says: show icons of UnPn devices in network

if you click on that it actually installs some stuff and now i see my router/modem under: local network

(what does this mean, does it mean everything works better now?)

[azOrion]

Try creating a static IP and forwarding your ports to that address. That was the final step I had to take to get mine to work.

[cybasyko]

Windows XP does not detect Upnp devices by default. This means, even if your router is set to support Upnp, Windows will not configure it's ports.

To enable UpnP, do the following: Control panel>Add Remove programs>Add Windows components>Highlight Networking Services and click Details. Install the Upnp user interface and restart your pc.

Before that I would recommend to reset your router to its default settings like Nat on, UpnP on...

If all goes well, all relevant ports should be configured automatically, and although your Nat type will come up as Strict on IWnet you shouldn't have any problem connecting.

BTW, people have been talking about how dangerous it is to use Upnp. If your pc is clean and not already compromised there's no danger. Configuring a router via Upnp does not make you more vulnerable to attack.

Very good explaination of how to enable UPnP on the computor.
Yes, I've done this know. And when windows started up there was a new message down at the clock that the router was found or something.

But, its still nat type strict. But maybe its working, who knows. Time to test..

[CircularLogic]

This all seems much simpler/easier than using a server browser and dedicated servers. IW was right all along...

in that list it also says enable peer-to-peer, does that give any advantage in this situation, or p2p games all together?

[cybasyko]

No advantages as far as I am aware. As far as MW2 is concerned, I have ignored the in my opinion wreckless advice of IW how to configure the router. Opening ports manually, disabling firewalls, even putting the pc into a DMZ is just asking for trouble, especially when people aren't excactly sure what they are doing.

[gustavlufsen]

No, this doesnt work at all.

We are now 3 friends only trying to play together.
But, cant.. since noone can create a party and invite.

All are strict.

Static IP can this be it?


Adresserar

Fysisk adress: 00:xxxxxxxxxxxxxx
Tilldelning av IP-adress: DHCP
IP-adress: 192.168.1.65
Always use the same IP address: Yes
DHCP-lånetid: "forever"

How to set static IP if this isnt static?
Dont know what static IP really means..

All I know is: This game has alot of problems. That could be solved by dedicated servers. :]

/G

Edit: My friend have opened the same ports. Have same internet and router Thomson TG787. NAT Type Strict

[crashie]

I play with strict settings enabled, but it ,might also be an IWnet issue, as it sometimes sets to strict and sometimes not.

I've not opened any ports on my router and it seems to switch itself, but neither affects connections to mp games for me.

this seems to be a problem for many more people. Did you follow my advice and undo all the manual changes you made to the router and just leave it to Upnp to configure everything? If you can't remember all the changes you made consider a hard reset in order to get everything to defaults. Then make sure that Nat and Upnp are checked and then see if you for example can communicate via Messenger or some other messaging program. If you can without manually opening ports Upnp is working.

You cannot change the Nat type in MW2. you can use your web browser to connect to your router's setup pages. Type your router's IP address into your browser's address bar and hit enter. The address is likely to be 192.168.1.1 or 192.168.1.0 - if it isn't, click Start>Run>type cmd and hit enter. At the command prompt type> ipconfig/all and hit enter.
This will show you amongst other things the default gateway address: This is your router's ip.

Once you are on the router's setup pages, undo all the changes you have made sofar, which means everything should be at default settings. Then make sure that Upnp and also Network Address Translation (NAT)on the router are enabled. Don't forget to save the changes you made, and after that reboot the router.

If you made any changes to the Windows Firewall, undo these as well. Upnp will configure the firewall for you. Let me know how you are getting on and good luck..

This definitely seems easier than DS and server browsers.

[cybasyko]

This definitely seems easier than DS and server browsers.

Absolutely. But seriously, in this day and age this shouldn't be an issue at all. This should be working right out of the box without messing about with settings. All this bollox IW are coming up with like disabling non-Microsoft services, disabling firewalls, opening ports manually etc is just pathetic.

IW take note: PC's are not consoles,they are not only used for gaming. It is your job to make your games run on this platform without asking us to make changes which potentially lead to problems with other apps and compromise our security!

[Cyberbob]

enable dmz

[Redfyre]

Yes. Open all of your ports on your computer.

Because that is COMPLETELY and ENTIRELY safe!
Right?

Oh, wait.

[gustavlufsen]

Now I reset the whole router to default.
UPnP active on default.

But this..

"Then make sure that Upnp and also Network Address Translation (NAT)on the router are enabled."

Cant find anything about NAT on the router. Wierd huh..
Thomson TG787

And Cyberbob as I said earlier, dmz CANT be enabled.

[ChemicalFyre]

Try going one step beyond turning off the Windows Firewall. Disable the service.

Hit Windows Key + R for a Run Dialog, type in 'cmd' without quotes.

on the Command prompt window, (you'll need admin for this) type the following:

net stop "Windows Firewall/Internet Connection Sharing (ICS)"

Make sure you use the quotes in that one. I've found that often times even though the firewall is disabled, it can still have an effect on your system. If that doesn't solve the problem, change stop to 'start' and re-enable it. Let me know how that works out for you.

I read about UPnP and NAT on router settings.

UPnP is activated, its always been for me.
NAT on router is someway built in the routers firewall.
I've tried turning off the firewall completely but It didnt help.

Isnt this weird that Portchecker says "Your port is open!" ?
And still it doesnt work?

Forget about DMZ, although it can be enabled on your router you don't want to get into that.
Have a look at this:

http://www.thomsonbroadbandpartner.com/getfile.php?id=5361 for the English version in PDF format.

Chapter 6 will walk you through configuring your router with Upnp. If you still don't get inviting friends to work it's most likely IW's fault.

Also add IGD Discovery and Control in WinXP. How to is also described later in that chapter.

[gustavlufsen]

Chapter 6 will walk you through configuring your router with Upnp. If you still don't get inviting friends to work it's most likely IW's fault.

Yes Im swedish.
And Yes, I read that manual 3hours ago.

And as I said earlier in the thread:

- UPnP activated
- UPnP installed on my computor
- Router is found on my computor

Thats everything the manual helping me with about UPnP.
And it's all correct according to the manual.

So its already done.. but didnt help with the manual.

Thank you all for trying to help me. Its great that people with experience are helping me.
The company Infinityward who released the game doesnt helping me.
And Steam doesnt answer my "support need mail".

So, if you have more ideas how to solve this. Please help.

I got answer from Activision that steam needs more ports open.

How to open port range, exampel 27000-27015
On this router Thomson TG787

This is the manual from portforwarding,
http://www.portforward.com/english/routers/port_forwarding/Thomson-Alcatel/TG787/default.htm

Use the Protocol drop down box to select the protocol type of the ports you are forwarding. If you are forwarding a single port, enter that port number into the Translate To, Top Port Range and the Bottom Port Range boxes. If you are forwarding a range of ports, enter the lowest number of that range into the Translate To, Top Port Range box. Then enter the highest number of that range into the Bottom Port Range box. When you are finished, click the Add button.

Click the Apply button near the top of the page.

Click Apply is not correct. But thats not the problem.
I can add singel ports, but not a port range.

Upper small box(port range) - 27000
Lower small box(port range) - 27015
Long box (translate to) - 27000

This is not correct. So, anyone knows how to open port range?
The manual is not correct, and the interface on this router model is bad.

I will report if this solves the problem and what ports I opened.

[gustavlufsen]

Hello.

It seems you have many of the ports open already, but there are larger port ranges that need to be open as well. Here is the list:
Call of Duty: MW2 transmits and receives network traffic on ports UDP: 1500, 3005, 3101, 28960 and TCP: 27015 (SRCDS Rcon port). Additionally the Steam client transmits and receives network traffic on ports UDP: 27000-27015, 27015-27030 and TCP: 27014-27050.

As long as all of those ports are completely open, you should be able to connect better with your friends.

Aha, the error is in the ports he said. 27000-27015, 27015-27030

Works with:
27000-27015, 27016-27030, 27031-27050

[gustavlufsen]

It'll work fine with strict, but when you go to invite friends from Steam and/or become the host, well you can't do either of those with strict NAT.

Hi Gustav.

I had the exact problem as you :(. I have this Router TG787 from Thomson. I've forwarded these ports (on both TCP and UHP)

27030 - 27039
1200
27000 - 27015
1500
3005
3101
28960
27015
27014 - 27050
27000 - 27030
57540
(NOTE: Some of these ports are for Steam too...)

After that: I disabled the built in firewall on the router, and then i restarted.

I launched MW2, and it showed Open for like 3 seconds, but then it went to Strict again! :confused:

So at that point, i thoight that this problem had to do about something else. So i double checked my router config, and then I tried to DISABLE the Windows Firewall.

And BAM! IT WORKS! :D

Now I'm host 75% of the time and I can join anyone! :)

So the problem was maybe the router, but mainly the Firewall.

The issue is the Windows Firewall. Just DISABLE it and it WILL work!

/Tom

[Appl250]

Digging this post up from the grave just to properly help people on Windows XP with GFWL NAT Strict issue when the router is not at fault because disabling the Firewall is something people do not want to do just to play a game.

First:-
Open control panel
Click on Windows Firewall
Click on Exceptions tab and click on Add Program
Search for the GFWLClient.exe and add to the list so it shows up in the exceptions list.
This SHOULD resolve the NAT strict problem.
If GFWL is still not set to open, empty the internet cache by going to:-
Control panel
Internet options
Under Browsing history in the general tab click Delete...
Check all boxes and click delete
