Port forwarding the same port with multiple WAN addresses.

[UnCoNoob]

Hello,

I have a question. Me and the wife play the same game and obviously require the same ports to be forwarded to 2 different LAN addresses which does not work (unless some one can inform me how). I have tried this and searched it up and have had no luck.

I was thinking if I get a second external IP (WAN) from the service provider can I have one machine run off one external IP and the other off the other external IP, Would this be possible to then open both ports to both machines at the same time???

I called the service provider and they see no reason why I can not get both open now but you know what they are like. I asked if there is an option to have another external IP added he said they are able to on a buisness plan which I would have to switch over.

So before I waste my time and money I thought I would ask the brains in here. Is one of these options doable? or am I stuck with a strict NAT while my wife has open?

Now I have run wireguard on a VPS for a few years and this works. The problem now is the game shadow bans all the VPS servers I have tried resulting in games taking 5 mins to find than having 300ms ping. Turn it off straight into a game 12ms ping. I have tried all the companies I can find to see if maybe one will work but it won't.
