I was under the impression a customer cannot replace AT&T routers. Do you mean you use a different router behind the box AT&T provides, or that there are viable replacements for the boxes AT&T provides customers to connect service?

I hope so. My EdgeRouter X is scheduled to come tomorrow. I have a fiber connection box coming in, which outputs RJ45. I am assuming the AT&T router can be replaced as it is just doing DHCP to get my public IP.

I'm really interested in knowing if you get this to work with AT&T without their gateway being in front of your router. I've been working on a project and have so far found AT&T gateways to be necessary for a working connection, due to certificates on the device (as mentioned by another comment in this thread). Care to share if you got it working?

It probably also does authentication to the upstream network, so it knows who's connecting and can provide usage metrics.

The auth protocols are generally standardised though, so you shouldn't have too much trouble. :)

Would the auth information showup in the AT&T modem admin page? They doesn't use PPPOE, just standard DHCP. Just hoping they don't filter by Mac address upstream.

Interesting. If they do use the device MAC address, that could turn out to be really easy. :)

Mac address spoofing is super easy (basic admin task almost) on most *nix's, though (from hazy memory) it does depend on the network card capabilities and driver.

Looking at the general info page for the EdgeRouter X, it seems to run something called "EdgeOS":

That has a user guide available:

Page 4 of the user guide says:

  CLI
  Advanced users can make configuration changes using 
  Linux commands.

If EdgeOS really is Linux based, you might be in luck. :)

On (V)DSL, they use 802.1X, not sure about their fiber service. That's what forces me to use their "home gateway" (since it auths using the certificate in the device).

[justinclift]

As a curiosity thing, have you ever cracked open the device to see what's inside? Maybe JTAG ports on the main board, or even having the cert stored (say) on microSD card? :D
