ATT Uverse RG Bypass (0.2 BTC)
-
@MonkWho I just want to say thank you for carrying the torch. I just recently discovered this whole workaround thing - was getting discouraged trying to find a way to build the netgraph for my SG3100 - then found out it is included with pfsense now. Except on 2.4.5, the ng_etf package is missing! lol
https://redmine.pfsense.org/issues/10463
So now I must wait until 2.4.5-p1 release to be able to set this all up. Anyways, thank you for carrying on the work @aus started.
-
@glio Maybe I am missing something, I am running 2.4.5 with the supplicant bypass. I did install it on an earlier version.
-
@AiC0315 The EAP proxy is not available without ng_etf being present. I've not previously set up this stuff on earlier versions so maybe that's the difference.
-
I've heard people being able to use the supplicant mode without netgraph if they used a switch or bypass switch between pfSense and the ONT. Can anyone confirm and what model switch did you use?
I tried this on my new physical firewall with a DGS-1005G and had no luck. Any one?
-
So based on what I'm reading over the past 2+ years pfsense still requires netgraph in order to work with the 802.1x certificates?
Also of note, someone on Reddit found a downgrade loophole for the BGW210-700 which allows root access. So you can extract the 802.1x certificates and disable the auto-updates to the gateway.

Is this expected behavior?
Running the netgraph bypass as documented at https://github.com/MonkWho/pfatt . No LANs have been routed to ngeth0 just yet.
I get about about one packet every two-three minutes from the RG: tcpdump -ei em4
10:06:30.887851 f8:2d:c0:yy:yy:yy (oui Unknown) > Broadcast, ethertype 802.1Q (0x8100), length 424: vlan 0, p 3, ethertype IPv4, 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from f8:2d:c0:yy:yy:yy (oui Unknown), length 378And I get about 100 per minute from the ONT: tcpdump -ei em5

- $ONT_IF = em5
- f8:2d:c0:yy:yy:yy / zzz-zzz-179-129.lightspeed.stlsmo.sbcglobal.net = my RG
- a0:f3:e4:59:27:94 / 162-224-176-1.lightspeed.stlsmo.sbcglobal.net = ATT

^^For the first one, I think that might be a byproduct of the rg not getting an ip when using the eap proxy method. That is, it keeps requesting, but because the proxy only passes 802.1x traffic, it never actually receives it.
The 2nd looks like the gateway is responding to a ping request? You have something pinging the gateway ip (162.224.176.1) often?
-
Sounds like the first one is benign, unless, it is an indicator that something else is wrong.
The second - I’m not pinging in on that IP.
Edit: The second thing, with the 100+ pings per minute, was the pfSense gateway monitor. It's now disabled.
-
What gateway box are you using? Maybe time to dump it entirely and go wpa_supplicant method?
-
@GPz1100 Worked on that last night, I’ve got the certs off of the RG and broken into PEMs. Will work on the rest this evening.
Bricked the gateway though. I think I left the file system RW when I rebooted. It’s in a boot loop.
Thankfully, I still have my Charter connection, so I’m not in an outage condition.
-
Can't get the supplicant mode to work.
I had to comment lines 205-231 of pfatt.sh to get the system to boot.
wpa_cli status says:
Supplicant PAE state=HELD
suppPortStatus=Unauthorized
EAP state=FAILUREtcpdump -i ONT_IF -e vlan says:
05:20:52.486546 f8:2d:c0:xx:xx:xx (oui Unknown) > 01:80:c2:00:00:03 (oui Unknown), ethertype 802.1Q (0x8100), length 22: vlan 0, p 0, ethertype EAPOL, EAPOL start (1) v2, len 0/conf/pfatt/bin/* is 755 and /conf/pfatt/wpa/* is 644
Certs import without error into the web configurator, if only to make sure that they're intact. I've since pulled them back out of there.
What could be keeping this thing from being authorized?

I just moved into a temporary housing situation and was told this unit has ATT U-Verse. I'm looking at the back of my current RG (BGW210-700) and it's using an RJ11 from "broadband" port to the wall. The wall port doesn't have an RJ45 connection. Are there any workarounds for this using this method?
-
Rj11 = dsl. You need fiber.

Uverse is the name of their interwebz service which can be DSL or Fiber. You could get a DSL modem if you don't want to use their equipment. If you have uverse TV service, or ATT home phone service, you'll need to keep their equipment in place.

I removed the gateway from my setup using the supplicant method from MonkWho's fork of pfatt from aus.
https://github.com/MonkWho/pfatt/tree/supplicant
This worked well on a SG-5100 on pfSense 2.4.5 p1 with certificates purchased on eBay from maczrcool. I'm getting full line speed (940/940) with no issues. I've tested that the setup survives expected and unexpected reboots.
-
@bk150 I'm trying to do what you've accomplished, on my PCEngines APU2 box with 2.4.5 p1 using MonkWho's fork. I have the certs extracted from my Arris BGW210. Did you also need Netgraph for the Supplicant approach? I was hoping to avoid it.

Just wondering what you used to extract the certs.
-
@JonH I used the python script method per:
https://www.reddit.com/r/ATT/comments/g59rwm/bgw210700_root_exploitbypass/
Had to run it twice because the script didn't have a wait period defined to account for telnet server startup leadtime, but on the second run it appears to have worked and was able to save the certs to my local machine in the manner documented in the readme.
-
Did you get this to work? I am trying to enable pfsense to be moved to a different system via vmotion for doing maintenance on the host. Right now I use the netgraph bypass method, but I don't think it will work if I am using PCI device passthrough, which prevents the VM to be migrated.
Does the vlan0 tagging get interfered with by vmware's management of the network interfaces? I can use port mirroring on a switch to make the ONT and even the gateway available on multiple systems.
thx
