Some Modems have built in Firewalls. I had to contact my ISP to get them to walk me through turning off the security in the modem. It made a huge difference in the performance of my online games. I went from NAT 3 to NAT 2 which is supposed to be the best. On MW2 my NAT type is usually moderate or open. The security of the modem doesn't concern me much since I have security built into my router and software on my computers.

Here is your solution. NAT should be open if you do this correctly.

 

 

 

PUTTING YOUR PS3 IN A DMZ

 

Firstly you may be wondering what a DMZ is, this stands for a demilitarised zone. it really means that rather than opening just one port on your routers firewall you are actually opening every single one. Port opening is another simple process, however it takes a bit of time to find exactly what ports need opening, and sometimes, the ports listed may not solve the problem you have

 

Putting your PS3 into a DMZ is not a bad thing, and is much easier than opening port for the reason listed above.

 

Now you may need to do this for some of the following reasons:

 

* Not being able to join rooms

* Not being able to speak over headset

* Not being able to hear over headset

* Not being able to join games which are hosted by certain people

* Any problems to do with connectivity to the PSN or game specific servers, especially if your computer will connect to the internet, but PS3 won't.

* Problems with media servers

 

Now on with the guide.

 

The Guide!

 

To put your PS3 into a DMZ (To be done on the PS3 Console)

 

Firstly, you will need to assign your PS3 a static internal Ip address. This means that everytime your PS3 connects or "talks" to your router, the router will assign it a different internal IP address. These IP addresses typically run in series. So for example, if your PS3 is the second device communicating with your router, then it will be assigned an ip address of 192.168.1.3. However, if you choose to use your PS3 without the computer being on, the assigned IP address your PS3 has will be 192.168.1.2. As this is different, and obviously will change, it would be stupid setting a DMZ up on one of the above Ip addresses, unless your PS3 was the only device that would ALWAYS connect using that specific IP.

 

To make sure that your PS3 is always assigned the same internal IP address by your router, you will need to go to the "Settings > Network Settings > Internet Connection Settings" option on the PS3 Cross bar menus.

 

You will be presented with an option which primarily asks whether you are using a Wired or Wireless connection. Obviously, you will choose the option which refers to you. If choosing the Wireless option you will need to input the security details in use on your router *If you are not currently using wireless security, i strongly reccommend you do so ASAP*

 

Both selections should show a page called "Address Settings". Here you will need to select "Custom". Another page will then display entitled "IP Address Setting". The option "Manual" will need to be selected.

 

This will display a page where customisable IP Addresses are available to be selected.

 

IP Address - This will need to have the Static IP address in it. Personally, i use 192.168.1.100. I use this because it is extremely unlikely my Router will ever automatically assign this IP Address to a device, as i will never have 99 other devices connected to the same system.

 

Subnet Mask - Is always set to 255.255.255.0

 

Default Router - Is the internal IP Address of your router.

To get the exact ip of your router you should go to

Start

Run

cmd [Hit Enter]

Type in ipconfig and hit enter, this should come up with all the ip addresses to do with your computer and the network. The address you will need to enter in this option is listed as "Default Gateway".

 

Primary DNS - Same IP Address as "Default Router"

 

Secondary DNS - Same IP Address as "Default Router"

 

After entering all of these IP Addresses, you will now click "Enter" or hit the "right" button on the D-Pad. This will take you to a screen which says "MTU" at the top. My setup has this as Automatic, solely because i haven't a clue what MTU actually means or does.This won't affect your ability to set up a DMZ.

 

The next steps are very simple. You do not want to use a proxy server unless you connect to the internet using one, however i can be of no help there, and you should enable UPnP if your router supports it.

 

To put your PS3 into a DMZ (To be done on the PC)

 

Now head over to your PC, and load up your internet browser. In the Address Bar, type the IP Address of your router (the one you found using the Command Prompt earlier)

 

This will take you to your Router Configuration Page.

 

Every router interface differs from an other, and depending on what router firmware update you last installed, router interfaces can differ, even on the same model routers. This means that you will need to search the router config page yourself. You are looking for any mention of "DMZ" or "DMZ Host"

 

When you have found this, it will ask you generally to input the IP Address of your DMZ Host, which is just the static IP address you assigned to your PS3 earlier, my example was 192.168.1.100, so we'll stick with that. Then click "apply" or similar.

 

You should then turn off everything running on your home network. PS3, PC, Router etc. This is solely to make sure that the changes are applied as soon as possible.

 

This should fix all of the problems as listed earlier in this guide, and probably some other issues.

That's nice info Cloud but... He says he still has the problem when he connects directly to the modem which is bypassing the router. So while I agree putting the PS3 into the DMZ is not a bad idea (as long as you know what your doing) It's still not going to fix security issues he might have with his modem.

 

I know this from personal experience because I put my PS3 into the DMZ and it didn't fix my problem until I disabled the firewall in the modem.

Well since this is in the Xbox section.. I'm wondering what a NAT 2 or NAT 3 means.!? ;D

BLACKCLOUD ]PUTTING YOUR PS3 IN A DMZ

And I'm not sure that ^ will help anyone in here.. lol

Will UF ever get over the PS3-ism. :P

 

 

I don't think the NET is the issue anyway.. My NAT always says open, but I still have problems joining in games & party chat. I think it is a different issue than with "NAT". (although i recently moved & my connection is nothing like it was before)

Recently i had it fail in an xboxlive test, & told me i needed to have a minimum of 1389 MTU setting.. so i guess i need to figure out what that means. :-\

PS3/Xbox the settings are still the same. The above posted instructions are for your router and can apply to just about any device on your network. The reason why this can get tricky is because putting your computer instead of your PS3 in the DMZ could be bad.

Yea i'm just giving you guys a hard time.. :-*

But these directions seem pretty much directed towards a PS3..

To put your PS3 into a DMZ (To be done on the PS3 Console)

 

 

After all Chaka posted this in the Xbox section, and as far as i know he doesn't have an Xbox. lol

 

And yea Routers are the same eitherway.. BUT NAT 3 or NAT 2 is a PS3 thing.. Xbox uses "Open", "Moderate" or "Strict". so to me the #umbers mean nothing. ;D

@Chili - You do have to remember that sometimes connection problems aren't only on your end. There's a chance that you might not be able to connect to someone because THEY don't have theirs open or they have a conflict with your connection. Mine is open, also, but I think Forza just prefers that I don't own you race after race.

Yes but in MW2 we get the same message on the left side of our screen it says Nat type open, moderate or strict. I'm guessing whatever message we have on the game affects how we are put into matches.

yup. If you or anyone in your party is not open there will be some issues. The NAT has to do with communicating with other PS3's. So if one guy in your part has moderate I believe everyone will some sort of issue. Like joining games and someone always gets dropped.
