I have Att gateway. Can I use Brume 2 to access my network as a vpn?

VPN

Edit: or could I actually just use a travel router? I don’t think att gateway allows for pass through

You will need to have port forwarding for the VPN server

ATT has passthough mode where it only acts as a modem. I had a mt1300 beryl attached to use the VPN for football games. I exchanged it for the Flint 1 this weekend because the beryl was getting warmer than i liked. I used youtube to set it up. I have the ATT-BGW320 router with fiber connection.

+1. ATT allows for bridging, so you can make your GL router the primary gateway and don’t need to worry about port forwarding.

6

Which I think att might not allow right…

7

This works… I have mine in pass thru to a pfsense box. Also I did see prot forwarding on my att hardware when I was setting it up.

Which GL router?

So replace att gateway with GL router then I can create a vpn to access it from elsewhere?

Thanks

If you can’t do it on the AT&T router then most likely you’re behind CGNAT which means you won’t be able to port forward unless you ask them.

10

You would need a GL router (like the Flint 2) to act as your server. If ATT provided you with both a modem and router then you can swap out the ISP router with the GL router. If they just provided you a single modem+router combo then you can connect the Flint to it and then put it in “passthrough” or “bridge” mode so the Flint becomes the primary gateway the public IP from your ISP is assigned to.

Doing either of the above means you won’t need to setup any port forwarding.

The other option is to just run a GL router as a server behind the ATT router, in which case you just need to set up a static port forward rule to allow Wireguard traffic to reach the GL device. In that situation you can save money and buy something simple like the Brume 2 as the server device.

I get what you mean

But the last option means I need to buy both brume 2 and GL router to stay at home right?

12

I bought the Brume 2 and have a att router/modem. I setup passthrough because port forward is not an option . I created the wire guard server on the brume. 2 as instructed in the setup guide. But when I set up the wire config file on my phone to vpn to my home network there is no connection. I don’t know what to do at this point. Also I noticed that my att ip and brume 2 ip address are not the same. Any advice??

13

Let me try to explain more simply.

If you wanted to replace your AT&T modem/router with a new router and not have to port forward, then you would want something like the Flint 2 which is a Wi-Fi router and would also let you run the VPN server on it.

If you simply want to run a VPN server on your already existing AT&T router (requires port forwarding), then just buy a Brume 2 (no Wi-Fi ability) and save money.

However, I saw your latest post saying you just wanted to access devices on your home network. If that’s the case, you don’t need a full Wireguard VPN. You can simply use Tailscale (same devices required as stated above). Also, in this case you don’t even need a 2nd router to travel with if you simply install the Tailscale app on your laptop.

14

ATT routers typically have port forwarding. I’ve set it up for dozens of customers. It should be under the advanced menu.

Passthrough/DMZ functionality is kind of a crapshoot with many ISP routers.

Thanks for the response

If you simply want to run a VPN server on your already existing AT&T router (requires port forwarding), then just buy a Brume 2 (no Wi-Fi ability) and save money.

If I did this, I wouldn’t be able to connect other devices at home via WiFi, right? Because bridged mode?

16

Bridged mode is not a requirement for your ATT router. You can continue using your ATT router as it is now and use the WiFi as normal. The only difference is you’d have the Brume 2 plugged into the ATT router’s LAN port serving as VPN for you to access the home from outside. This requires port forwarding.

I might try this

I tried with Xfinity but could never get it working. I had to buy a asus router that had built in WireGuard functionality in it

18

Do you have a guide on how to port forward att router to brume 2?

19

Xfinity makes it super easy! With their mobile app you just go to the gateway and Port Forwarding settings and it literally takes 5 seconds.

So, port forwarding varies by router. And each ISP has many different models of router. But generally it’s straight forward (I did it for a client with AT&T yesterday).
