I have 2 Xbox One consoles on my Virgin Super Hub 3.0 network (wired via power-line adapter). This causes errors whilst attempting to play multiplayer games, the solution is port-forwarding? I checked, & Activision state that the ports that require to be open are:
88 UDP 3074 UDP & TCP (for the 1st Xbox One) 53 UDP & TCP 80 TCP 500 UDP 3544 UDP 4500 UDP 3075 UDP (for a 2nd Xbox One) 3076 UDP (for a 3rd Xbox One)
So, I have both Xboxes set to static IP addresses. I port forwarded Xbox One 1 to 3074 I port forwarded Xbox One 2 to 3075 Hub 3.0 firewall: ON UPnP: ON Power Cycle the consoles before play: YES
With this set up we get: Xbox One 1 Console: Open NAT (behind cone NAT) / Infinite Warfare: Moderate NAT Xbox One 2 Console: Open NAT (behind cone NAT) / infinite Warfare: Moderate NAT
So, the consoles sat they are open, but the game says moderate, which is less than ideal. Also I've tried to open ports 53, & 80, but they will not open?
Any tips on how to get the game to give me open NAT?
port forwarding can only forward the ports to a single host behind the NAT device. So having two XB1's behind the NAT means you could only forward all the ports required to a single host (Xbox).
Your second XB would have to rely on UPnP to function correctly, which it looks like it is anyway.
Depending on how Activision classes 'moderate' it could just be defined as: a player behind a NAT device with the necessary ports open.
Normally if a host is 'open' to the internet it's publicly facing and there is nothing stopping ANY external traffic from getting to it. This isn't a great solution as it means any traffic that isn't legitimate will also be allowed on to your internal network by the exposed device, be it PC, XBox, PS4 or smart TV that has been put in the DMZ for no reason at all.
Also if I remember correctly, if two devices are connected behind the same IP the game servers sometimes don't like this as they will sometimes detect this as some form of exploit. Though I could be wrong and I'm thinking back several years of gaming at LAN parties with several PCs behind a single NAT (router) device.
