Hey guys,

I had issues with Strict Nat for MW3 and spent many hours looking for a soluttion!
I've put this together from a few posts i have read and this sorted the problem for me!
hope this helps others

this is a guide to obtain OPEN NAT in PS3 COD MW3 with Thomson TG782T Modem

Windows 7 has Telnet Client closed as default! it can be quickly re-enabled by following these steps:

Start
Control Panel
Programs/Programs And Features
Turn Windows features on or off
Check , "Telnet Client"
Hit OK

After that you can start Telnet

Step 1- On your PC - click on start
- In the window "search for programs and files" type "run"
- In the "run" window type " cmd " this is the command window.
- Copy and paste this command. telnet 10.0.0.138 (press enter)

This will open a telnet session with your modem, you will then be asked for a Username and Password.

Username: admin (press enter)
Password: your modems password (usually blank by default) (press enter)

Step 2- copy and paste these 4 command lines one at a time pressing enter after each one is done.

:connection bind application=CONE(UDP) port=3074-3075

:connection bind application=CONE(UDP) port=3478-3479

:connection bind application=CONE(UDP) port=3658

:saveall

then close the telnet session

Step 3- Reboot your modem (just power off and back on) not always needed but is helpful to do after changes made.

Step 4- Open Call Of Duty modern Warfare 3 on PS3, go to multiplayer and enjoy your OPEN NAT gaming from now on

Note- you can close "telnet client" once you have completed the following steps

I am using my normal modem password but it allways replies that its incorrect! I tried it on my phone and on other laptops I have and it works just fine!

Does not work. Have been trying to get a mates going and this did not work.

I think the Telnet session User name and Password are different from your normal modem password,so try as instructed

also this is for the tg782t modem supplied from Bigpond,it may work for others?

please post repley if you found this sollution handy

When i did this after a while i could not connect to any games and i could not go into the internet either on my pc it said "server error", i had to reset my router every time this happened which means i had to reset every 45 minutes. Please Help.

Try do a modem factory default reset which will return it to factory settings and remove and changes!
just remember it will also reset your wifi password so keep that in mind.

good luck

Thanks i did that after my internet stopped working so my nat type is strict again do you have any idea how to make it work.

thanks for the help so far.

Your opening ports to allow Open nat and im not sure what caused your problem
I can only suggest trying this method again and see how it goes?

good luck
