Network DMZ?

[gamer1978]

Hi I have a Playstation 3 and have heard about connecting to network via DMZ.  I have seen it recommended for connecting to networks I don't no what DMZ is and have never heard of it before.

 

Is there someone who could explain what DMZ is and how to enable it I have a Netgear WGT624 router and have looked in the configuration page and couldn't find DMZ.

 

Any info on it would be great and thankyou for the reply.

In computer security' date=' a demilitarized zone (DMZ), based on military usage of the term but more appropriately known as a demarcation zone or perimeter network, is a physical or logical subnetwork that contains and exposes an organization's external services to a larger, untrusted network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's Local Area Network (LAN); an external attacker only has access to equipment in the DMZ, rather than the whole of the network.[/quote']

Assigning a Default DMZ Server

To assign a computer or server to be a default DMZ server:

1. Click WAN Setup on the Advanced section of the main menu.

2. Type the IP address for that server. To remove the default DMZ server, clear the Default DMZ

Server check box.

3. Click Apply.

WGT624v4 Reference Manual

 

Although I don't use Netgear products I believe they also refer to the DMZ as an "Exposed Host" in their setup pages.

 

I hope this helps you.

Thank you for the reply my next question is.  The default IP for DMZ on my router is 192.168.0.0 wich is confusing because the IP for router is 192.168.0.1

 

I have also set my PS3 with a static IP of 192.168.0.7 should I use that IP for the DMZ.  Does setting the DMZ on my router with IP  192.168.0.7 give unrestricted access for my PS3.

 

Thanks again.[br]Posted on: March 16, 2008, 03:22:48 PM

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 which I, myself have not encountered yet.

 

If you have any questions, please list them in this thread, and i will endeavour to answer them as quickly as possible. however if I do not reply, i'm sure other people will to help you lot out

The short answer is, yes and yes.

 

You should be good to go after setting it to you PS3's static IP.

do we all set them at 100? or just coincidence?
