You may be wondering what a DMZ is, this stands for a demilitarized zone. It means that than opening port on your routers firewall you are actually opening every single. Port opening is another simple system, however it takes a tiny bit of time to find exactly what ports require opening, & sometimes, the ports listed may not solve the issue you have.
There is no risk regarding security/virus’ etc when using this with the ps3, your router will only send the traffic through to the DMZ that you have specified by static Ip address. Putting your PS3 in to a DMZ is not a bad thing, & is much simpler than opening port for the reason listed above.
First off, you will need to assign your PS3 a static IP address. This means that every time your PS3 connects or “talks” to your router, the router will assign it the same internal IP address. You need to do this because IP addresses usually run in series. So for example, if your PS3 is the second tool communicating along with your router, then it will be assigned an IP address of 192.168.1.3. However, in the event you select to make use of 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 dull setting a DMZ up one of the above IP addresses, unless your PS3 was the only tool that would ALWAYS connect using that specific IP.
Before you start you will need some knowledge from your network, this is the way you will get it. To get the exact Default IP address and DNS severs address of your router you ought to go to your computer and then Start>Run. Type in cmd and hit Enter. A black screen will open this is called command prompt. Type in ipconfig /all and hit enter. This ought to come up with all the Ip addresses to do along with your computer and the network. The addresses you will need to enter in this next option is listed as “Default Gateway” and “DNS sever”. Write down your Default gateway address.
Go back to the ps3 settings now that we have that info. To make sure that your PS3 is always assigned the same internal IP address/static IP 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 introduced with an option that says simple or custom select custom. Next you will be asked wired connection or wireless. Obviously, you will select the choice which refers to you. If choosing the Wireless option you will require inputting the security details in use on your router. After choosing your connection type you will notice an option for Auto-Detect or Manual Settings. Select Manual Settings. You will then see an option for speed and duplex. Select Auto-Detect. You will then see an option for Ip address settings. List Automatic, Manual or PPPoE. Select Manual. After entering all of these IP Addresses, you will now hit the x button or the “right” button on the D-Pad. This will take you to a screen which says “MTU” at the top select automatic for this setting.
Next you will notice Proxy server. Most of you will select DO NOT USE. You do not require to make use of a proxy server unless you connect to the Web using, however in case you do use I can be of no help to you. Next you will notice an UPnP setting. You ought to select enable UPnP. Most routers support it. It is meant to be an automatic port opener. It is kind of redundant to make use of, but should not hurt anything. In case you get errors when you check the connection later on, then turn this off & try again. NOTE: In case you are having issues receiving game updates & or being booted from games in the coursework of online play, matchmaking issues stuck connecting to sever. Try disabling or enabling UPnP if it is enabled.
Save your connection and go to the next step here about setting your router up before testing your Internet connection on your ps3.
