GUIDE: PUT YOUR PS3 IN A DMZ

I have followed all the ps3 instructions but on the pc settings i cannot find anything to do with DMZ??

i use wireless network on 'zyxel'

 

does anyone read what I write in here? LOL rhetorical

PM me if you need help. What kind of router do you have for starters?

 

Hello everyone,

So I went out today and bought the Linksys wrt54g2 router and plugged it in to create a new network. I got the network set up and the only thing that is connected to my router is the PS3. So I created a Static IP and went into the router itself and configered the DMZ to enable it and open all the ports. When going into gameplay on COD Modern Warfare 2 It still tells me my NAT Type is Strict. How can that be if all my ports are open? I am starting to lose all my patience with this! Someone please help me!

 

I see that you have all ports open, you may want to try Port Forwarding as well. One other step that you can try it Port Forwarding does not solve your problem is Port Triggering. Port Triggering is easy as shown here http://forums.tutorialninjas.net/tutorials-news/667-possible-way-open-your-nat-type-linksys.html
Try port forwarding first.

 

Great guide, I have no problems whatsoever playing on my PS3.

I am using a linksys WRT54GC v2.0 Compact Router.

My problem occurs when I try to play TWO playstation 3's connecting to the same router.

When trying to play Modern Warfare 2 one of them will never connect and always gets the message "trying to connect, matchmaking"

Whatever PS3 I switch on first works fine, its when you try to play the 2nd one for online gaming, the 2nd one will not connect.

I get NAT type 2 easily on both.

Both PS3 have their own Static IP addresses
192.168.1.105
192.168.1.110

Both PS3 work fine when you play them without loading the other one up.

It is only a conflict when you try to play the same game on both.

We can play different games and it works fine. example, she can play Modern Warfare 2 and I can online with Demon Souls or even Dragons Age or Pro evo 2010.

It's when we BOTH try to play MODERN WARFARE 2.

Is anyone else getting this error?

We have 20mb broadband and everything else works fine.

Someone suggested it may be a lag/latency with trying to connect 2 PS3's. I find this hard to believe as it works when we play 2 different online game.

I have read afterdawn, yahoo answers, portforward.com and anything else that showed up on google. Most solutions are only for getting a NAT2 on a single PS3.

I have uPNP enabled on my router. I set up an internet connection on my PS3's and select "ENABLE". When the final screen shows up on settings the uPNP is always shown as DISABLED on the PS3. Does this matter? I have no idea how to fix this as I always choose to enable it.

Help?

Suggestions anyone?

 

Oh, and does anyone know the exact ports to forward on Modern Warfare 2 on playstation 3.

I suppose I could try first PS3 in a DMZ and the second PS3 with port forwarding.

Forgot to mention I am using DNS 4.2.2.2 and 4.2.2.3

 

Check with MW2 what your NAT type is.
The ports needed for open nat is port range 3074 to 3075.

 

Once you have your router in a dmz you shouldn't have to use a static ip address. Just use the automatic settings and it should connect fine.

 

Im NAT type 2. It's fine. 2 is the best you can get through a router.

Single PS3 works fine.

TWO PS3's still do not work at same time.

Thanks for the port numbers.

Anyone any idea which PS3 to forward them to so that both work at the same time?

I've got a feeling the router is getting confused with 2 playstations trying to access same game at the same time, even though it's two different PS3's

My other PC's and laptops all work fine. My PS3's work fine on their own.

Bloody MW2 seems to be the only game that stops me playing both online. Well MW1 blocked me as well. Is it an anti-cheating thing because it recognises both MW2 games as the same IP address from the router?

Automatic settings are all well and good but you can only put ONE PS3 in a DMZ not both.

 

If you manually sign each PS3 a static ip, add a service to your router with said ports, call it what you wish (i called it PS3Nat) then in your routers firewall add to inbound section and input the two ip,s you created earlier, with this done you shouldnt have to place any of your PS3,s in the dmz.

 

Hmmm my router will not let me forward those ports to BOTH PS3s

It will only let me assign them to 192.168.1.200 OR 192.168.1.205 (my current static IPs for both PS3s)

I assigned both an IP address no problem, as they already had their own.

I looked for an "add a service" option like you suggested, but could not find one. Could it be called something else?

My "firewall" section in the router just allows me to enable or disable it, there is no option that I can see for an "allow inbound" section

I am using a Linksys Compact WRT54GC version 2.0 with the latest firmware from the linksys website v1.01.5 from the download section.

My playstations access the internet fine and plays game online fine.

It is only when I try to play Modern Warfare 2 on BOTH at the same time that the problems start. From browsing the internet it seems like a common problem people are having.

The only solution I have seen online that someone got it to work was have one on wireless and one on wired connection. I just tried that and still the 2nd one will not hook up to online mode.

PS3 will end up in the garden soon

 

Does it not give you option for ip range?
Starting ip finishing ip?
It could be called somthing else alright, i use a crappy sagem router i got with sky broadband.

 

Afraid not. No option for IP range, only port range.

I'd love to know if there is another router out there that will allow Modern Warfare 2 to run on two PS3's at same time.

I am reluctant to buy a new router since this is the only online game that will not work with both running at same time. Seems like an awful lot of money to spend just to get 1 game to work.

Also, is there any router out there that will allow you to put 2 IP addresses into a DMZ. WRT54GC from linksys only lets you assign 1 IP address to DMZ.

Thanks everyone for your comments so far.

 

You can only Port Forward One device per Port #. The idea behind port forwarding is telling your router that any time information comes in on a specific port, it is to automatically be sent to a specific IP address. This cuts down on information transfer time because the router does not have to connect to every device on your network and ask if this information should be sent to them. Thus, only one device (PS3) per Port Forward range. CODMW 1 and 2 requires information to be sent over the above listed Ports. If you lock down one PS3 to those ports, the other one will not have access to thoes ports. If you don’t Port Forward either PS3, both will have access to the necessary ports but will probably not have a NAT Type 2 connection. The only way that I know of getting around this is to get a second router. You would have to go from your Modem and split to two different routers. In each router, you could port forward a PS3. Sucks don’t it. Btw, this is not a PS3 thing. Common problem.

TCP Ports: 27014-27050 UDP Ports: 1500, 3005, 3101, 27000-27030, 28960

This is a good link for any ports that you may need to forward for any game. http://www.portforward.com/cports.htm

 

Thanks glassd

I take it replacing my wireless router with a wired unmanaged D-link switch will solve this problem too?

Since it auto forwards everything and no firewalls etc.

Just a thought.

 

OK here goes....

A few months ago I tried port forwarding but was still unable to join multiplayer rooms, it would only allow me to create rooms and once more than 2 or 3 people joined, I would get a message saying that I was disconnected from the game session. I set my PS3 under a DMZ and everything worked fine. I just recently rearranged the furniture so I had to unplug everything and plug it all back in. I checked the settings and everything was the same so I assumed everything would be ok. I logged in to play GTA 4 and it said I needed a PS3 update so I downloaded it. Now I am having the same problem as before where I can't join any multiplayer rooms. I set up the DMZ again and reset everything and it is still not working.
Static IP: 192.168.2.10
Subnet: 255.255.255.0
Router 192.168.2.1(Belkin F5D7234-4)
Default Gateway: 192.168.2.1
Nat 2

Please someone help me.

 

Try resetting your ps3 internet settings to AUTOMATIC ...do not use a static IP. If you are in NAT2 that should work. See if that works.

 

Now every few tries it will put me into a room with 3 or less people. But it is still mostly having me set up a new room, giving me the disconnected from game session error, or saying that the connection to one or more players have been lost.

 

If you are in a DMZ and ps3 shows Nat 2 you shouldn't have a problem. Is it possible someone else with a gaming system is using your router? Do you live in an apt. condo etc? If not maybe your router is not a good gaming router. Try a base linsys wrt54gv2 very cheap and works well. ~supertape

 

Switch did not solve the problem.

I have exhaustively tested everything.

The only way to play 2 copies of Modern Warfare 2 online TOGETHER in the same household is through 2 different broadband suppliers.

But to quote a previous post "Sucks Eh"

WB8383: Supertape is correct, check if anyone else in your household using gaming system as it can really screw you up, I have only noticed this personally though when using the same game. What I havent tested myself I have thoroughly researched.

My static IP address worked best when used outside the routers DHCP range of 1~149

So set my PS3 to:

IP: 192.168.1.200
Subnet: 255.255.255.0
Router: 192.168.1.1 (I noticed you have 192.168.2.1 - are you using more than 1 router?)
DNS1: 4.2.2.2 (my network provider is 194.168.4.100)
DNS2: 4.2.2.3 (my network provider is 194.168.8.100)

You could try both of the above settings.

Also, if you are the only gaming console connected in your household and the AUTOMATIC DETECT isnt working, then you have not connected your system cables properly.

Good luck.
