Re: How to put PS4 in DMZ?

@

Thanks for the reply and explanations, I think I understand now.

So the DMZ allows inbound connections from the internet.

Then if someone from the internet tried to connect to 5353 they would be forwarded to 65535 where the packets would be dropped.

I have the 2ac router so i assume my start port would be 5353 and end port 65535.

Also is having mdns reachable from the internet a threat because it can show an attacker what is on your internal network?

Thanks

Re: How to put PS4 in DMZ?

The 2ac won't let you forward to a different port so forward port 5353 to an IP that's not used on the network instead.  I suggest 192.168.0.253

MDNS can do more than that, by spoofing the return address (possible as mDNS uses UDP rather than TCP/IP) they can co-opt your PS4 into being part of a DDOS attack against a poor unsuspecting individual.

Re: How to put PS4 in DMZ?

Hi I am using the super hub 2 trying to follow your tutorial but when it comes to the port forwarding I am bit confused as I don’t have an internal and external start port. I just have one showing on the screen.  Do I need to set up two one for 65535 and 5353?

my nat type on COD is still showing moderate I was hoping doing this would make it open.

Re: How to put PS4 in DMZ?

On the earlier hubs the external and internal port numbers are automatically identical so the trick I use has to be modified slightly.

You only need one port forwarding rule and that is port 5353 and you set that to go to an IP address that is NOT in use e.g. 192.168.0.254

The reason for the rule is to ensure that requests from the Internet to port 5353 are dropped quietly, as the PS4 responds to these requests when it shouldn't meaning that your PS4 can be used by hackers to take part in a DDOS attack without your knowledge.

Re: How to put PS4 in DMZ?

Hi Raven,

Followed the steps below.

what do I need to do on the ps4 side?

Manually set PS4 to 192.168.0.254 gateway 192.168.0.1 DNS 194.168.4.100 and 194.168.8.100 and DMZ to IP 192.168.0.254

 

Do i need to do the above?

Also when logging into the hub, it says my ps4 is 100mbs with the tivo at 1000mbs is this capped? see screenshot below.

 [MOD EDIT: Image removed as contains MAC address]

Re: How to put PS4 in DMZ?

You don't need to do anything on the PS4 side.

The whole point of the changes is to redirect mDNS queries from outside the network to an unused IP address so that they are dropped.

Re: How to put PS4 in DMZ?

Hi coming back to this thread after nearly a year later and theres 4 pages of responses which is good. What responses have i missed out on or was there anything new added?

Can someone do a summary answer please accounting for these 4 pages as it will be easier for beginners coming to this thread. 

Finally I have the latest 9.1.116.608 firmware. Anything new I need to do reflecting from this new firmware?

Re: How to put PS4 in DMZ?

I still don't know how to setup NAT1 on PS4, I don't even know if this is possible with Virgin media, tried to read guides here but can't understand them, it's easy to understand if you already know this stuff, for newbie like myselft it's too complicated :/
