BGW320-505, Eero 6 Mesh, Mine Craft

I have a AT&T Fiber (1GB) coming to my home with a BGW320-505 Modem/Router combo.  I use the 2.4Ghz Wireless for some older devices and for everything else, I use my Eero 6 Mesh wireless.  Everything works pretty well.  I don't have any passthrough or Cascaded router set-up yet.

My Problem:  I have set-up a MineCraft Server on my Mac Mini to play MineCraft with my Grandson.  It works great internally from anywhere.  When I try to reach it from the outside world, it does not work.  I'm not sure of the right configuration and port forwarding to do to make it work.  I've researched on this forum and cannot find the combo that should work.  I was hoping someone would provide me some education and advice.

Thank you.

If you are using another router with your gateway, the recommendation is to set the gateway to pass-through mode and let the Eero handle all of the heavy lifting and WiFi. You can still use ethernet on the gateway. What you want to avoid is a double NAT because that can cause issues.

For your 2.4GHz devices, just point them to the Guest Network (which is always 2.4GHz) or assign a different SSID and pw to the Guest Network and then point your devices there.

Thank you @OttoPylot.  

is there any other settings I need to change?  I’m wondering if I do port forwarding on the Eero after that or is there something I need to do in the BGW320-505?

I don't use AT&T gateways so I'll let someone else who does direct you in how to properly setup your gateway to use with a separate router. All of our 2.4GHz devices use the Guest Network (with a different SSID/pw) and there are no issues. All of our other WiFi devices connect to the primary network with zero issues. Other devices, like our home theater systems are all hardwired to the router (Netgear Orbi Mesh WiFi 6).

Here is a great tutorial showing how to to implement IP Passthrough for connecting a third party router to your AT&T gateway.  You would do the port forwarding on the third party router, not the BGW320.

I agree, there must be something that's making the Minecraft Server hard to connect. Usually that's with just the AT&T gateway so hopefully you'll have more success with the router in IP Passthrough.

So far I've set-up IP Passthrough and my port forward on the Eero Router.  I connect a laptop to an alternate network and I cannot get to MineCraft.

I've checked the IP address (on Eero) it matches my Mac.  I've checked the port (that matches).  It still feels like there is a firewall or something blocking...when I tracert....it just times out.  Once in passthrough is there anything else on the BGW320 that would block the request?

Hey there @mstearnssr. Thanks for reaching out to us about not being able to connect to your MineCraft, and we'd be happy to help you. 

 

We appreciate @OttoPylot and @tonydi for providing that helpful information to set your gateway in IP Passthrough mode. 

 

Just to confirm, when you say the "outside world" are you referring to trying to connect to the service from outside your home network? Are you able to connect to the server when you're using your home network to access it?

That is exactly right. Works great inside the network not outside. My next step was to plug my laptop directly to BGW320 and see if I can run from there. However if you have thoughts please advise.

Thanks for clarifying that for us, @mstearnssr!

 

If you're able to access the server when connected to AT&T Internet, and you aren't experiencing any service issues outside of being unable to connect to the Minecraft server, we recommend reaching out to the Minecraft support team for further assistance.

Please feel free to reach back out if you need help in the future. Thank you for contacting the AT&T Community Forums!

So, I think I'm not explaining it correctly.

Mac Mini (MineCraft Server - Port 25565) --> Eero Mesh (Port Forward) <-----> (Passthrough)BGW320-505 ---> Internet

                                                                                         ^

                                                                                         :

                                                                                         :

                                                                                         :

                                                                                         V

                                                                     Laptop (MineCraft Client) - Works

Mac Mini (MineCraft Server - Port 25565) --> Eero Mesh (Port Forward) <-----> (Passthrough)BGW320-505 ---> Internet

                                                                                                                                                          ^

                                                                                                                                                           :

                                                                                                                                                           :

                                                                                                                                                           v

                                                                                                                           Laptop(MineCraft Client) - Does NOT work

So not sure why that is...it almost feels like something is blocking on the BGW320-505.

Hi there, mstearnssr. Let's break down what is going on with your Minecraft server access. 

 

To make sure that we have some clarity on what you are trying to do, let's review what you have already done and the equipment you have. 

 

You have the following equipment:

  1. The BGW 320-505 in IP Passthrough 
  2. You have the Eero Mesh doing the portfowarding to Minecraft port

Just to make sure that you are not doing both IP Passthrough and portforwarding on the BGW 320-505, because those operations cancel each other out when it is done on one piece of equipment. 

 

You stated that when you are home that sever works properly. That is because you are using an (in network) connection.

 

So let's look at things from the outside world.  Are you able to ping and traceroute to the server address? If not what errors are you getting? The reason why we asking, so we can get you the support that you need. 

 

Looking forward to hearing from you soon.
