2 gaming consoles 2 routers 1 modem

I have 2 ps4s one modem and two routers wired dedicated to each ps4 is it possible to achieve open nat on both of these it's so frustrating to play with friends if me and my roomate are playing one of us gets kicked or one of us goes strict other open please help Both routers are plugged into modem!

Likely not. Your ISP will only allow you to have a single ip which means only 1 router can have a IP. If you are willing to pay for it there is a possibility the ISP will allow you to have 2 ip and 2 routers. Hard to say technically it is possible but they may not offer the service.... or it may be too costly.

So I have to have two ip address I can set static ips to the ps4s but what would be the benefit of having two ips I'm confused I called about adding another modem for the house and they gave me the run around and told me it was not possible unless I had a business account with Comcast but both routers are set up to talk to the ps4s the right way I belive but both routers are plugged into the Comcast modem

Lets pretend you don't have a router. You plug both ps4 directly into the modem and you have paid the ISP for 2 addresses. Each ps4 now has its own real public routable IP address and will work fine. Be aware these IP are actual internet IP not the private 192.168.x.x that your router give out.

If you use 2 routers or plug the 2 ps4 in directly is not the issue. Putting a router infront of each ps4 just makes things more complex but the end result is the same....each ps4 gets to use its own public ip address. The problem is the ps4 assumes it has full control over the ip address and if you only have 1 actual ip address the ps4 will fight over it since they both assume they are the only ps4 on the network.

So there is no real way of solving this without a second ip what if u plug both ps4s one router with static ips set one ps4 into dmz and the other open ports could that solve it! I don't think Comcast will let me have a second ip without a business account

 

[James_lewis]

So if they give me a second ip how do I configure everything

 

[bill001g]

Does no good. Both ps4 want to use the same ports that is the whole problem. A single port can only be used by a single machine. When you use 2 ip you in effect get 2 copies of the same ports so each can have their own. If the ps4 would allow you to pick the ports it uses there would be no problems sharing.

 

[James_lewis]

So what I would need is a static IP address from my ispp

 

[bill001g]

They do not have to be static but you need 2 PUBLIC ip addresses.

Ok so I have set up business class with Comcast 30 day trial I will have a installer soon and I will be paying for two static IP address I hope this solves are connection issues I lowered my speed tier down to keep my bill the same so I hope all goes well wish me luck
