multiple gaming devices 1 house and single ip

[atomic7431]

So a friend has 2 playstations and 2 pcs sometimes all gaming at the same time.

He has an asus rt-ac5300 router and wants to know the best option to get their games to an open state on the networking.

The issue is say 2 pcs want to play black ops 4, with upnp off and manually port forwarding the game requires port 3074 to be forwarded to each machine, or the netwrok says its moderate and may have issues connecting etc.

Now they cant forward the same port to 2 different pcs and as far as im aware you cant change the port that a game uses.

Upnp has had issues where security is concerned and causes some problems with certain games (BF1 and 4) connection issues.

How do you get around this, im no expert but try to help best i can.

thanks for looking.

Needs public ips for each device ideally.

You are right that you can only forward a port to one device. You'd have thought the consoles would have tried to get around this by now.

Additional wan ips assigned to those devices will fix it.

UPnP is meant to make this not a problem, as the consoles can use any external ports they want and negotiate that, but some games seem to just strictly require certain ports and don't want to know any different.

You won't get open NAT with a single public IP and multiple hosts behind it. IPv6 can help as it removes NAT from the situation, but AFAIK only Xbox Live really implements it, and even then it varies depending on which game you're playing.

Depending on how the games get on with cloud providers you might be able to deploy something like pfSense/RouterOS into AWS, give it multiple public IP addresses, build a VPN tunnel from your house into AWS, and then NAT each device to a different address.

A&A offer something that looks interesting, and might be able to give you an IP block (for an additional cost) if you asked them: https://aa.net.uk/broadband-l2tp.html. You'd then just need a cheap Mikrotik router to plug the consoles and PCs into.

Turn on upnp, this is what it's for.
