(adsbygoogle = window.adsbygoogle || []).push({}); Putting your PS3 into a DMZ (demilitarized zone) simply opens all of the ports on it.

If you have the following problems, this is likely to fix it.
Not being able to join rooms
Not being able to speak over your headset
Not being able to hear other people over their headset
Not being able to join private games
Any problems to do with connectivity to the PSN, especially if your computer will connect to the internet, but your PS3 won't.


(On PS3)

Firstly, you will need to assign your PS3 a static internal IP address. Normally whenever a device connects to your router it will be assigned a different internal IP address. These are normally 192.168.1.2, 192.168.1.3, 192.168.1.4 and so on. Assigning a static one will ensure that your PS3 will get the same one every time it connects.
Go to the "Settings > Network Settings > Internet Connection Settings" option on the PS3 XMB. Choose whether you are using wireless or wired.
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 customizable IP Addresses are available to be entered.
IP Address - This will need to have the Static IP address in it. Use 192.168.1.80, simply because it is unlikely that 80 other devices will be connected at the same time.
Subnet Mask - 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"
Proxy When you get to the proxy screen, select "Do not use Proxy"
MTU Automatic
UPnP Enabled

This should optimize your gaming to keep your ps3 from kicking internet ever so often and also show overall improvement

yup, as far i know once you DMZ your PS3 you have to make the same changes on your router and sync on the same form.

look:

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, (The place where you put [url]WWW.)[/url] type the IP Address of your router (the one you found using the Command Prompt earlier under "default gateway")

This will take you to your Router Configuration Page.
There may be a security login page or popup. if you don't know the Username and password then Google your router for the default login, check on your router label or ring your ISP.

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 192.168.1.101, 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.

If you do need any help then when you post, along your with problem could your also give some more details. Like:
- Your Connection, ADSL or Cable.
- How you have your network setup.
- Your router Make and Model.

Nice guide, thanks!

Going to try this method right after I attempt to force host, usually when I'm host & not lagging or anything, I hit those teleport lags across the map lol. Hope this works!

This speed up my internet a bit
