How to: Speed up your PS4 Internet connection with DMZ (by JMQMOfficials)
Note from Wololo: This tutorial was initially published by /Talk member JMQMOfficials, as part of our monthly tutorial contest. JMQMOfficials won the best PS4 tutorial prize (a $20 PSN Code) for his entry. You can find the original post here.
Update: as you can see in the comments section below there are strong concerns about the related security issues and actual usefulness of this technique to improve your internet speed. I am leaving this article here because I hate it when websites just “remove” an article as if it never existed; but please follow this guide at your own risk.
In this tutorial, I will show you how to speed up your internet connection. You will need a computer and the credentials for your router.
Important note: “DMZ” comes with implicit security limitations. Do not apply this speed improvement if you have concerns for the security of your network, or in general if you don’t know what you are doing. To quote user STAticKY:
“DMZing” an ip address opens ALL ports that DONT have a current portforward rule.
this an extreme security risk and is why dmz’s are used to catcah all “other” traffic and forward it to a server(the DMZ’d IP) that is isolated from the rest of your network.
problem is in these setups that you describe, there is no DMZ server, just a PS3 in its place. So sure, your opening it right up so i will most probably go faster, but depending on the rest of your network, that ps3 isnt safe from me…
EDIT: also if you have multiple consoles this wont work
First off, go to your settings
Go to Network
Select Set Up Internet Connection
Choose WiFi or LAN, depending if you use a cable or not
Select Custom
Choose an internet connection (if you have a password, fill it in)
Now when it asks you about IP Address settings, choose manual
Go to your computer and open up your command prompt (search -> cmd)
Type in : ipconfig/all
Remember or write down your default gateway number
You will see this image after selecting manual
Type in the following :
- IP Address – Your default gateway but the last numbers changed (ex. 192.168.0.111) (recommend 3 digits)
- Subnet Mask – 255.255.255.0
- Default Gateway – Default gateway
- Primary DNS – Default gateway
- Secondary DNS – leave blank
Now select Next
Select Automatic for MTU
Select Do Not Use on Proxy Server
Do not test internet connected, just press O and turn off your PS4
Now you’re done on your PS4 side, and onto the PC side again
- Open your browser and type in your default gateway and press enter
- Log in using your router’s credentials
- Go to DMZ host or DMZ settings (might be in firewall settings)
- Change your DMZ host address to the IP address from your PS4 (my example was 192.168.0.111)
- Save settings and logout
- Turn on your PS4 and test your internet connection
Complete! If this does not work, change it back to their defaults.
This worked for me greatly, I had 7.2mb/s before, and now I have 14.9mb/s. Very effective.

Do not do this. I work at an internet security company and know this is a HUGE risk. Learn how networking really works, buy good hardware and you will be fine. Shame for allowing this post on here 🙁
I would agree with mink. Furthermore this does not actually fit the definition of a Network DMZ (Demilitarized Zone). Please check http://en.wikipedia.org/wiki/DMZ_(computing)
Actually it would be a big risk if dmz was set to a computer. Setting dmz to a ps3/4/vita should not be much of a risk.
As to usefullness, the other program that benefits for being able to accept incoming connections is torrent. IDK if vita uses dynamic incoming ports, but if it did, and upnp was unavailable, this could help.
Also, did anyone stopped to do ‘before and after’ test before commenting? or just guessing?
That sounds suspiciously like something a pragmatic security analyst would say. Next you’ll be asking me to stop scanning my encrypted traffic for viruses.
The ‘before and after’ was regarding to if there is an effective increase in speed. Not regarding to security.
“Actually it would be a big risk if dmz was set to a computer. Setting dmz to a ps3/4/vita should not be much of a risk.”
Agreed. PCs have enough exposed services that there’s a real risk of attack if those ports aren’t blocked (though admittedly RCEs of that nature are getting increasingly rare), however Playstation consoles have very little exposed since they are locked down devices. At best (worst?) you have a handful of services exposed such as Remote Play, which in theory could let one take over the console, but in practice it’s difficult to imagine getting past the device pairing requirements. And if someone could pull off an attack that would result in arbitrary code execution, then that would actually be a good thing in the end since it would be the means to allow us to hack our own consoles.
The biggest flaw in this article is that DMZ is going to be relatively useless, especially if you have UPnP. Otherwise this should be harmless; Sony has these consoles locked down so well that hacking them would be doing us a favor.
This is a horrible suggestion. As mink says, HUGE risk, this is just stupid.
Not to mention the fact that this wont “speed up” you internet connection, that’s capped upstream by your ISP and no amount of ignorant software setting changes, even those with high risk of extreme consequences will ever change that.
This article should be killed with fire.
This won’t do much for you unless you have UPnP disabled. If you have that disabled, just go enable it. DMZ is a huge security risk. If for whatever reason you can’t use UPnP, just google for the ports the PS3 uses and forward those. There’s little reason to ever use DMZ anymore between UPnP and port forwarding.
I should correct what I typed: There’s little reason to ever use DMZ anymore between UPnP and port forwarding, at least for the standard user.
Im a long time DMZ’r. What is that “huge security risk” everybody talking about?
Can they hack my PS4 acc because i opend all ports?
I don’t know about playstation specific, but opening all ports to a device means that anyone can can use any protocol (that the device supports) to connect to that device from the outside world. If I were to use my pc as a DMZ server, anybody that knows my ip address can open a telnet/ssh/ftp connection to it. You can protect yourself a bit with passwords, but you are basically removing one layer of security by setting a DMZ server. Passwords can be guessed…..
Why not just open up all the main ports the PS3/PS4 uses instead?
Is this the same as downloading stuff using Internet Download Manager? (so it breaks up the download into 8 chunks to maximise speed?).
as others are saying, this is about the worst suggestion given for anything speed related. From a networking standpoint unless your router is doing something terribly wrong there is no speed gained from what’s being done here. The speed “gain” reported by the author could have been time of day, network health of his ISP, test location, LAN, etc at those particular times he tried. From a security standpoint it opens all unassigned ports on your PS4 to access from the internet. Virus? No probably not. But you, nor Sony, nor every single game developer can know what OTHER publishers/devs are going to do. Game software vulnerabilities and exploits typically don’t show up on security sites but that in no way means they don’t exist. And the reason for that is BECAUSE most consoles sit behind a firewall with only the ports used through PAT/NAT as needed.
“Secondary DNS – Default gateway but last number increased by 1”
Sorry, but that information is just wrong. Leave it blank, do not put a non-existing IP that field.
Thanks everyone for the comments. I take note, and the feedback here is really appreciated.
I won’t remove the article because I hate it when other websites do that, but I added what I think is a clear disclaimer at the top of the article. I apologize for publishing this without doing proper verification, I’m usually better than that
There should be no need to use DMZ, if your router is set up correctly. If this increases your network speed – there is obviously something wrong between your PS4 and router.
The correct solution would be to troubleshoot that issue and figure out what’s wrong – not bypass the protection. Sure it’s a shortcut, but the security disadvantages this opens up are far more risky.
I just did this with my PC and I think it increased my net speed, well according to speedtest.
Should I continue to do this on my PC?
P.S Nice site layout Wololo.
Don’t do it on a pc unless you have a firewall (other than windows firewall).
Just forward the ports you need for the application you need.
Don’t do this.
It’s a risk. And I doubt that this improve speed. (Anyone have really done it and make a speed test before and after).
I work with telecomunications. And think it only improve a little the first part of the connection when the PS3/PS4 get the ip from the router. And its done only when you switch the console on.
He won money for this garbage? Wow, that sucks.
ok folks, this is a hacking site and this tutorial is a hack. he won rightly.
I know I’m late to the party, I just couldn’t stop myself from commenting anyway.
I have worked professionally with IP networking since the mid 90’s and I have NEVER seen such a bunch of *** in one single text. The other comments pretty much sums it up – this doesn’t really do anything at all except put your PS3 fully exposed to the internet, if the setup even works at all. Nothing would go faster since the traffic still has to go through the router. If it “solves” anything it’s because the network was broken or some other reason.
I wouldn’t worry so much about security on this PARTICULAR setup – the ps3 is pretty secure (as have been shown…) but there is no point, and it quite likely will make any other devices on the network having issues.
The whole article is so technically confused and full of obvious lack of fundamental TCP/IP knowledge (DMZ is “catch all IP? *** are you talking about?”). It almost looks like a troll. (If so – well played, sir – to get this published on a hacking site is no small feat! You won teh internets AND the cash o.O)
Every site has it’s low water marks, and I hope this was the lowest it’ll ever go. Jebus Wololo, what were you smoking? Rig some voting system for your users if you don’t have the time to even look at the “winner” article and let them decide instead).
While I support the general idea of just not removing an article and pretend like it’s raining you should … I don’t know, change the entire text to a strikethrough font or something.
The creators of teh intertubes weep today 🙁
no matter what I do to my *** TG 782 router it always says Nat Type 3 and it doesn’t let me host games and sometimes my mic doesn’t work either.
I have opened all the ports in the Sony website on TCP and UDP, I have put my PS3 in DMZ, I disabled the router’s firewall, I have done everything I could. And my ISP provider are so incompetent they don’t know what “NAT” even is and all they do is blame my PS3. They say it’s an issue with the console when it’s clearly their router because when I had an older one I never had any issues but it broke down and that’s why I now have this piece ***: Thompson-Alcatel TG 782, worst router ever. But for some reason when I try to look for more info about my router the one that appears is: TG 782T.
I will go in a different direction and thank the author for such a useful article. Actually those steps will not speed up your connection. But it helped change the NAT Type. I used to suffer from the “Moderate” NAT type on my PS4. But after using the DMZ, it changed to NAT Type “Open”.
And there nothing much to hack in my PS4…meh
So, thanks buddy
I already put my ps4 in DMZ mode. Is there any chance that my psn can get hacked?
There is some merit to this. Not speed perse unless you have a bad quality router, but can improve stability and reduce lag since packets are just forwarded to dmz IP address with no processing overhead. Can also be helpful say if your connection lags and router stops waiting for replies on an outgoing connection or if state table is full. UPnP can be flaky and game has to request the right ports. As to risk, almost none. To exploit an open port, first a service to exploit needs to be listening on it. Generally, that just isn’t happening with game consoles, unlike with a PC. All the would be hacker would get is “connection refused” when no service is listening.
so now you can access to my PS4 with static IP address to ssh . are u crazy ? don’t do that guys because your router now will forwarding all port from out to inside your ps4 so its mean access to ssh will be open so don’t do that
this article was intended to show someone how to setup dmz for a ps4, NOT a computer. i don’t see the issue here, because it isn’t a risk at all. i guess cops aren’t the only ones who jump the gun.
You can also take advantage of the afdfordable Uber or Lyft car service; allowing you

Hey peeps.
Adam the noob gamer here.:) Im having issues with my connection ive tried to dmz,port forward and disabling upnp and ive learnt more about networking then i ever thought which is good. My isp is iinet and im starting to think its there new router. (TG1) The worst of my issues in the ping department it started a few weeks into my 2nd month with iinet otherwise my speed was average for wifi. 8mb a sec down. Which is to slow i know and i should have a wired connection but the contract has ben signed by my dad and this is what iget for the time being. My ping was tested and its just below 120. What now??? ive talked to my isp and feel like i helped there staff understand port forwarding and static leases a little so im speading the knowledge i guess. Here are few Q for you guys. Is disabling all firewalls on my pc then turning the power off keep the computer safe? My ip is dynamic so does that mean all my efforts will be daily reconfig of my device settings or worse useless? Would 6 metres be too far from my router. Dns setting im keeping at my def gateway is that the right option? When i port forward is the wan and lan port the same? And finally would factory reseting my ps4 do anything? Thank heaps guys my psn id is budsky82. Seasons greetings from the Gold Coast Australia.
P.S also the sales dept told me i would have no problem with gaming for call of duty on wifi i feel like ive been deceived but have no proof. Would i be right to push further on this matter. All typed by ps4 controller so there willbe typos Cheers Adam.
See “Managing Integration Gateways,”
I would argue that network-wide uPnP is actually a much greater security risk than DMZ-ing a PlayStation. The main security risk I see from this is the chance that your dhcp server assigns that IP to a different client on reboot. DO NOT do this unless your router supports address reservation.
This won’t speed up downloads, but it could be useful so you don’t have look up which ports to forward on every single game you play.
I messed up by doing what it says before reading the comments. And now my computer won’t connect to websites. How do I reverse what I did when I chose the ps4 as the DMZ host?
