Xbox gamepass/open nat - Battlenet & Steam/moderate nat BO7

[Wr3ck3r]

Having an issue with Battlenet and Steam moderate nat in BO7 but it goes to open nat in Xbox gamepass. Normally this is never an issue. Any help or trouble shooting steps would be great.

The fact that it's open on gamepass means you have an open NAT, it's just that the server testing your NAT may be blocked which is giving the moderate reading. If you disable the Geo-Filter and restart the PC you'll likely see it go to open.

J'ai déjà eu le cas, en règle générale le serveur de test NAT est bloqué par le geofiltre sur les applications tierces.

Vérifiez la carte geofiltre au lancement du jeu pour voir si un serveur est bloqué ?

Ok. So this is the only way I can get open nat for battlenet and gamepass. I have the R3 set up as Lan from Xfinity gateway to Wan on the R3. I put the R3 in dmz on the gateway. The gateway is not in bridge mode. I have no port forwards on the gateway either. The R3 dhcp is reserved. upnp is disabled. I have two port forwards of 3074 & 3075 tcp/ucp. Battlenet uses 3074. Gamepass uses 3075. All of this gives me open nat. On top of that...I have two network cables going to my pc. The motherboard has a 2.5g that I have the R3 plugged into. I also have a 10g card for my gateway. If I unplug or disable the 10g card, my nat type goes back to moderate. When both cable/cards are active, I have open nat. So, when I start a game, it uses the 10g card ip address but the geo filter still works great...excellent ping, no issues whatsoever. The funny thing too, if I create a port forward on the gateway for my sons pc, my pc game goes right back to moderate nat type. I delete the port forward, my nat type goes back to open. It's so confusing...lol

That doesn't make sense, if its using the eth card connected to your gateway then it's connecting through the gateway, not the R3. More likely it's connected to the R3 and you're just getting an open NAT through the R3 - connecting to two different routers on your PC is likely to confuse the NAT situation even more. Keep UPnP enabled, you can keep the port forwards for the moment and see if you get an open NAT with the 10g card disabled - reboot the PC when you disable it. 

Did you do what I mentioned about just disabling the Geo-Filter before launching the game, do you get an Open NAT then? If so then you don't need to worry.

[Wr3ck3r]

Alright...10g disabled/unplugged, upnp enabled with port forwards still active...open nat...ip address in game reads as the one from R3 (of course). Now everything is running as it did before. What is confusing though is why was the geo filter still doing its thing while the 10g card was active? The game ip was the one assigned to the 10g card when it was plugged in. Oh, and yes, I did do what you suggested above. It didn't work. I believe that's when I decided to start testing things with the 10g and 2.5g. I wonder if I create a port forward on the gateway for my son if I'll see any issues now? I shouldn't since I unplugged the gateway line...but all of this has been strange.

[Wr3ck3r]

just did a test...enabled upnp on the gateway and my nat went right to moderate. 

[Netduma Fraser]

Yeah I've no idea why that would have occurred, maybe it would have switched over but that doesn't make sense really. Good to hear! Is your son connected to the gateway or the R3? Really ALL devices should be connected to the R3 for the best experience possible and UPnP should then handle his device, so no port forward needed on the gateway.

To give you some info about why you're seeing NAT moderate after making the port forward on the gateway, with the R3 in the DMZ you've told the gateway - any traffic coming in, whatever it is just pass it straight on through to the R3. By adding the port forward to it you've told the gateway - any traffic coming in, follow the DMZ rule but also any traffic for this specific port pass it through to this other device as well. So you've created a contradiction, you're not telling it to pick whichever it wants, you're literally telling it to do both at the same time. It's like driving down the road and your sat nav says you must go straight on but also right as well, you can't do both and you can't split the car in half to fulfil travelling in both directions.

[Wr3ck3r]

Everything is running smooth. My pc has no issues with open nat now. I have my sons pc directly wired to the R3 and he is getting moderate nat. I noticed in the settings that his comp. doesn't show up in UPnP when I start up his game. My pc shows up requesting a port no problem.

[Netduma Fraser]

Good to hear! You can port forward 3076 for them and it should work in theory

[Wr3ck3r]

port forward didn't work. His game is using 3074 which is what mine is using.

[Netduma Fraser]

I'm not sure where you saw 3075 from for game pass but it needs 3074 as far as I can tell so then set 3075 for the other PC. Once done, reboot the router, wait 4 minutes then launch your PC and game first, it should use 3074, then do theirs and it should use 3075 and be open

[Wr3ck3r]

from what I have read...3075 is used for xbox consoles. So I'm thinking that is why gamepass is using 3075 even though I'm on a pc. btw, that is my alt account I play on. Battlenet is my main. I also read that two pc's in the house running the same game...one will be open nat on 3074 the other will be moderate on 3074. I haven't found anyone that has found a workaround for this. 

[Netduma Fraser]

I assume you're both trying to play CoD is that right? If so, that uses 3074 for the first device that plays and then it should force a second device to use 3075 if 3074 is already being used. However as you've eluded to, getting an open NAT on multiple devices can be difficult.

[Wr3ck3r]

Nothing seems to work. His pc connects to 3074 no matter what is done. It was a longshot anyway to get him to an open nat. I ended up putting him back on the gateway and leaving my pc as the only device connected to the R3. Thanks for all the suggestions...it's been a great learning experience.

If his keeps forcing 3074 then you could remove your port forward for 3074 and change it to 3075 and see if it works that way instead. No worries!
