Strict NAT for -Multiple- Devices Black Ops III | PC & PS4

[Jerry1161]

I recently acquired a Linksys EA9500 AC5400 wireless router. I have a Netgear C3700 N600 modem/router. I can not achieve open or even moderate NAT for any of my devices. The only thing that worked once was port forwarding for one device. This didn't help the other devices because you can't port forward to multiple devices and DMZ never worked. (DMZ sucks anyway) Port forwarding isn't even working anymore. Soon we will have three PS4's and three gaming PC's. All are hardwired to the EA9500.

Can anyone help me figure out how to achieve open NAT for all of my devices? Thank you!

It would be nice to know how you currently have each router set up.

The most basic way is to leave the first router with DHCP enabled on it.

And for the second router to firstly directly connect a laptop or tower based system to it via a Ethernet cable.

You should then using the browser of that computer.
By inputting the default gateway IP address or via the information on the underside of the router to log into the router menu options.

On the EA9500 you should disable Dhcp of the router.
Along with the hardware firewall of the router.

When connecting the EA9500 router if using a Ethernet cable to the C3700 N600 modem router you should connect the router to one of the Ethernet ports provided on the back of the router, and not the port labelled as Wan.

This will then treat the router as an extension of the network setup and configured by DHCP of the Netgear C3700
N600 router.

Where any device such as a Ps4 connected to the other Ethernet ports of the Linksys router will be assigned a working free IP address from the Netgear router, and with the same subnet address and default gateway address.
And the two Dns addresses for website IP lookup.

The port forwarding should then be set up on the Netgear router for any device connected to the Linksys router via a Ethernet cable with the IP address the Netgear gave for example to the ps4.

Along with the ports that need to be opened for the Sony playstation network, and the set games you wish to play.

The Linksys is basically treated as an extension of the Netgear modem router as if you added more Ethernet ports the back of the netgear router from.

This way you only have to deal with the port forwarding of all devices connected to the linksys.
on the netgear router.
