ATT Uverse RG Bypass (0.2 BTC)

@aus looks like I was able to pull nearly full line speed with the bridge on a E3-1230V6, I saw ~112+ MB/s when pulling a public linux distro torrent.

Thanks for the update! Glad you were able sort the speed issues out.

I wanted to come here and post a giant "Thank You" for all the work aus and others helping him put forth.
I was finally able to get my SuperMicro C2758 pfsense box working directly with the fiber ONT.
I have 4 Gig ports configured as follows:
igb0 - AT&T Fiber ONT
igb1 - L3 Switch
igb2 - UVERSE DVR - VIP2250
igb3 - RG - BGW210One thing I've noticed, is the RG only ever has a single GREEN LED lit. I've powered cycled the RG and the fiber ONT and everything still worked, so.... //shrug//
My throughput is fantastic (I have Gig service) and my latency dropped ever so slightly as well. Now, my task is getting the DVR to work. Coincidentally, my old unit died, so I just received my replacement.
One thing I noticed, is the UVERSE LAN needs the AT&T DNS Servers in order to work. I can't filter them through Cloudfare, or other.
I had IGMP Proxy setup just fine with the old box, but now it doesn't seem to be working. Any thoughts? -

You should probably start another thread.

This is normal and expected. The RG never reaches full green status because it is expecting to negotiate a DHCP lease. However, netgraph drops that traffic because pfSense is handling the DHCP. You can actually keep the RG disconnected after the 802.1X EAP-TLS authentication completes. However, if your igb0 looses its link (due to power outage, unplug, reboot, or whatever), you will loose connectivity until the RG is reconnected and can authenticate you.

This might be true for set top boxes or DVRs, but your entire LAN does not need to use AT&T DNS servers.

There's been a few threads about configuring the IGMP proxy for AT&T. Basically, it involved adding some of AT&Ts IP ranges. I had it working a while ago, but no longer have TV service to test. You might continue the conversation here:

Definitely accepting PRs if you figure it out.

Correct. The rest of my LAN has Cloudfare DNS servers assigned. The UVERSE DVR is the only thing that needed to see the AT&T DNS Servers.

I figured it out, sort of. I had been trying to nail down every multicast server I could see through pfTop, but it was still hanging up on a lot of channels. So, I instead made a blanket 0.0.0.0/1 (pfSense won't let you use /0) statement in the Upstream setting and every channel came through. This might seem terrible, but remember my UVERSE DVR is on its own separate LAN independent from my normal LAN. Also, this still won't work until you setup an allow rule through your firewall. I believe I only had to setup an alow rule to my UVERSE LAN for 224.0.0.0/8. There might have also been an allow rule for 239.0.0.0/8. I'll have to check it out when I get back home.

Just wanted to chime in and say that this worked great for me. I also have some static IPs from ATT (10$/mo for 5 extra) and I was able to utilize them no issues without the gateway.. Not sure if it was mentioned how to before.
I did so by creating an another lan interface tagged to vlan 99 dubbed Public Vlan. I assigned the "Gateway IP" given to me by ATT to this interface. after some proper firewall rules to allow traffic from outside to this network and disabling NAT on those addresses. I can confirm the public ip subnet is able to get out and traffic does return as desired. If you need more information just PM me

@aus Thanks for your work on this. https://btc.com/cae38d113459909c8b23dc20553628cdc79a2150ed87c9724701fcb95f67814c

Thank you! That’s very generous of you and much appreciated. I’m glad this solution worked for you. Cheers!

@Dade I figured out the static IP, I just setup 1:1 nat, it was pretty straightforward.

I set this up a month ago and worked great for 2 week so. Then for the past 2 weeks my connection will drop randomly every day or few days. My logs are linked below. But another question I have is the link to the gateway suppose to work also? When I connect to it it says there is no link and to contact ATT but my PFsense internet works.

I believe @aus stated that (the gateway not having link) is expected since all traffic from the gateway other than authentication is blocked.

Has anyone here using this bypass method noticed the WAN lease time obtained from ATT DHCP is only 1 hour long? Apparently people using other bypass methods have noticed it as well (see here) It only seems to happen when bypassing the gateway. The lease obtained when using ip-passthrough mode is much longer. I can see that in /var/db/dhclient.leases.ngeth0 the leases are 3600 seconds and going a grep "renewal in" /var/log/dhcpd.log shows the lease renewing every 1800 seconds which is the 1/2way point of a 3600 second lease. I'm curious if anyone can come up with a way to increase that lease time. I tried using a "send" dhcp-lease-time option to increase it, but it didn't help; the lease obtained was still 3600 seconds.

@gfeiner ok thanks. But any idea why my connection drops?

What is connected to igb2? The ONT or the gateway? Your logs are showing link going up and down on that port. Bad cable or faulty device connected to that port.
-
@gfeiner igb2 is the gateway. I will change the cable. I did also turn of gateway monitoring to see if that does anything.
-
@gfeiner I think I know what was wrong. I have the Pace 5268AC gateway and I did add the script to help with the EAP-Logoff issue. But when i added the script to the /rc.d folder I forgot to add .sh. I added it and now see it running in the logs. Hopefully this was the issue.

I just got the ATT 1g service, internet only, no TV or VOIP. The RG is BGW210. I changed it's IP addr to 192.168.100.1 because as delivered it was the same as my pfSense box. Passthrough gives me a 5 minute lease although the setup screen is has a different lease time.I have an SG-2440 and behind that an unmanaged 1g switch. My speedtests run around 550 Mbps, the RG Diagnostic menu has a speed test built in which shows that it is doing ~950Mbps.
I realize my setup is double NAT, I am reading here to find out if I can get rid of the double NAT and if that will increase my throughput.
I'm still seeking more info on the pfatt patch.
