How to Put Your PS3 Into a DMZ !! (laymans terms)

Hey Everybody, this is my first blog..........ever, so work with me here. Lately, I've been seeing a lot of people asking questions about their PS3 and the DMZ. Here's the deal, if you're using your PS3 with a router, whether wired or wireless, and you play online, you should put your PS3 into a DMZ. You wouldn't believe the difference this could make when it comes to online gaming. Also, to do this, you will need to have access to a PC/laptop that is connected to the router via wired or wireless connection. OK, let's get started.

Oh before we begin, there's some terms you NEED to be familiar with before we begin. Even though this a layman's term blog, there are some terms that you have to know. These are not Websters definitions by the way -

1. -DMZ- Demilitarized Zone -This is pretty much an area on the router that is not behind a firewall(security wall). The firewall is what actually slows down the speed to and from your PS3, so if you can get from behind it, your speed will be a lot faster.

2. -ip address- -This is pretty much how the network identifies your device. Every thing that you have on your network has an ip address. Think of this as the device name on your network.

3. -default gateway- -This is pretty much your router's ip address. This is the gateway to all the devices on your network. Everything connects to the router.

There are more terms that you can learn, but these 3 are the most important.

Ok, now that we got that out of the way, let's begin....for real this time. The first thing that we're gonna do is find out some info so we can do this right. On your PC, hit the start button (bottom left of the screen) and, if you have xp, click on run, then type in cmd.exe, then enter. If you have vista just type cmd.exe in the start search at the bottom and click on CMD at the top. A black screen should come up. Now type in "ipconfig" just like that without the quotation marks and with no spaces, then enter. When you do, a whole bunch of stuff will come up. We're only concerned with 2 things....the subnet mask and the default gateway. They should be fairly close to the top. Write these 2 down exactly as you see them. Congratulations you just found your default gateway!!

FYI - the ipv4 address that you see is the ip address of the PC/laptop that you're on.

The next step is setting up your PS3. The path you will take is as follows: Turn on PS3 > Network settings > custom > wired or wireless. If your PS3 has a wireless connection to your router, select wireless, and either scan or enter your wireless network info ie SSID, WEP key, etc. If it has a wired connection you can skip that step, but you'll have to select manual settings then auto-detect for speed and duplex.

Now we're at IP Address Settings...select manual. THIS SECTION IS VERY IMPORTANT!!! Start at the default router and enter in the number that you got for the default gateway. Put this same number in for the primary DNS. There's no need for secondary DNS at this time. Next put in the subnet mask that you wrote down earlier. Finally at the ip address(top) put in a number where the first 3 numbers are the same as your router, but make the last number different. For example if the default gateway was 192.168.1.1, make the ip address 192.168.1.110. Notice the 192.168.1 part is the same but the last number is different. Make it a high number, something like 120 or 110 that way you'll most likely pick a number that isn't already taken by another device on your network, but we're gonna check that. I have mine set at 110. If you have a lot of devices on your network, you may want to go even higher, like 200 or 210. ALL DEVICES ON THE NETWORK HAVE TO HAVE THEIR OWN IP ADDRESS. When you're done hit right on your controller to move to the next section. After that, the rest is easy.

The rest of the way should be like this - Automatic > Do not use > Enable. Now you're done. You can test to see if you have a connection if you want to, but we're not done yet so it may not work yet.

For the last part you need to be back at your PC/laptop. Remember that default gateway? Well you're gonna use it again. Open internet explorer and put those exact numbers into the address bar. This will take you to the web based configuration tool for your router. You will most likely have to put in some kind of login name and password. I know the default for linksys routers is the login name is left blank and the password is admin. For any other router brand you should google that company's name and "default login" and your specific model no. if you know it. Once we're in the software, you're gonna look for either Firewall settings of some sort or applications/gaming setting of some sort. I can't tell exactly what it's gonna say because all routers are different. Once you find these settings look for either DMZ or DMZ host. Once there, just enter in the ip address of your PS3( the ip address you entered on the PS3 in IP Address Settings) and your PS3 is now in the DMZ. Some routers may ask you to specify if the DMZ is just for outbound, but you want it to be for inbound and outbound. Congratulations!!!!! You've just set your PS3 up for a DMZ!!

While you're in the router configuration software, if you want to make sure your PS3's ip address is not the same as another device on your network, go to something that says my network or something similar to that and you will be able to see all the devices(ip address's) that are currently connected to your network. If you have a device that you turn on and off ie xbox 360, ps2, etc you may want to turn them on and have them connected so you can see that they are not conflicting with your PS3's ip address. Also you can change your login name and password if you want while you're in here.

If you get stuck anywhere during this process remember google is your friend. You can just about google anything and find info on it. Remember this is a layman's term guide, but if you would like more info you can google "PS3 and DMZ" and click on one of the various links from that search. I hope this helps someone out there. Good luck and happy gaming.
