UPnP or Port Forwarding for 2 PS4's in same LAN

[Ninjawebby]

Hi All,

 

Any ideas on best way to deal with two PS4s on same LAN, with same public IP. 

 

Im running UPnP which is working ok. Is there a way to port forward to both PS4s without having to have two public IPs? 

 

Cheers

The IP address in the portforwarding settings is going to be the assigned ip address from the R1 router or private ip address if I am not mistaken.  And the R1 router is going to give each playstation it's own ip address.  I am not sure what you full setup is but this is the case if your primary router is the R1. Public IP address is the ip address assigned by your isp to your modem. Private IP addresses are assigned to your devices by your router.

 

I don't think you can portforward the same port  to two different devices because I believe they are going to be assigned two different ip address from the router.

Correct can't port forward same port aka cod bo3 3074 udp. Some people have tried putting 3075 and so forth. But you can't put 2 devices on same port. No router allows it

Hopefully they will remedy this in the next firmware because technically you should be able to assign 2 seperate External ports to the same Internal Port and it will work but most SOHO routers will not accomplish this successfully.  The R1 will infact forward external ports to point at the correct internal port but for some reason the translation is lost I've only seen one manufacturer of SOHO routers do this with success, Netgear R6250-R8500.  We have 5 Ps4 in the house and have tested every router available in our area.

I've been researching this in anticipation of getting a second xbox. But don't know about PS4.

 

Multiple xbox 1's  can have open NAT if you use UPnP. The 2nd xbox will switch to another port if the port is already taken.

 

UPnP only works well when both the router and the network devices have implemented UPnP well. Unfortunately many routers (including many free isp routers) have implemented it poorly.

Didn't know of any router that supports same port on 2 devices. Nothing to do with firmware. It's how networking works. Sorry. You could Google this yourself. To see more in depth answer

Sometimes a work around is static ip each device. If port such as cod is udp 3074. Second device is set 3075 and so forth but this doesn't always work. Just like gta is udp 9306.

Hey, I would set a static IP for each device in DHCP lease and port forward according to https://support.activision.com/articles/en_US/FAQ/Ports-Used-for-Call-of-Duty-Games

could you elaborate on this more. as under dhcp lease it has mac address rather than an ip. and do you list the port where it says host number?

[Netduma Fraser]

For the device you want click the reserve check box and then input a number between 100-250 and then apply.

[Paddee1987]

does it have to corralate with the ending ip?

[Netduma Fraser]

I'm not quite sure I understand the question. You can input any number between that range in DHCP lease. Then when port forwarding you would need to input the number you reserved to successfully port forward for that console.
