Sorry I moved over to the stripper switch method to get rid of the complex ngeth0 scripts so I can't comment on this.
Would still love to run native using PCP 7 but waiting on the wpa supplicant to be patched to be able to support VLAN 0.
Could not get stripper switch to work on pfs 23.05 (one of the switches from https://github.com/MonkWho/pfatt/issues/82). EAP auth succeeds but will not get DHCP address. Might that depend on FTTN/FTTH and ISP upstream setup (hence why certain switches seem to work for some but not all)?
-
@t41k2m3 Does pfatt with netgraph work for you? I would expect a stripper switch to work as well then.
I haven't tested 23.05 yet, but 23.01 worked just fine with the switches mentioned in the https://github.com/MonkWho/pfatt/issues/82 thread.
If pfatt/netgraph works, verify you're using the correct mac for the wan.

I'm on 23.05 and using stripper switch (5 port) successfully. Didn't have to change anything going from 23.01 to 23.05.

Do any of you have this to working with the newer AT&T gateways with a built-in ONT?

Hi folks, I'm crossing over from a post I made in the general forum: Quirky bypass on 22.05 with AT&T fiber
-
I've got the 'official' bypass working with 23.05 and a BGW210, but my pfsense bootup is now quite a bit longer. It's taking about 75 seconds at "configuring wan interface" when it used to take just a few seconds before I performed the bypass.
-
The RG's LED indicator for 'broadband' flashes green while PFsense is booting, but then switches to flashing red after a few minutes, despite the baypass working and having full connectivity on my connection. This is a lesser issue, but I'm just confused by it.
I appreciate any insight as to why the wan config is taking so much longer, or why the RG wouldn't seem to detect the broadband connection. Thanks in advance!

I have the BGW320-505 gateway which AT&T started installing out about two years ago when I moved last. I’m curious if your method will work on mine. The ONT module is built-in, so they ran the fiber line directly to the back of the modem with an SFP module.

It's possible the authentication always takes a while but you wouldn't normally see that because the AT&T router does it before pfSense even connects in the double NAT setup. In the bypass mode the auth can only start once pfSense bridges to the router when it sets up the WAN. It seems unlikely it should take anything like 75s though.....
I don't have an AT&T connection to test. -
Since you can't really eliminate the newer AT&T gateways completely (thanks to AT&T's certificate-based authentication and integrated ONT module), then I don't even see the point of doing this. I just put mine in IP passthrough mode with my public IP going over to pfSense along with my /29 block and I haven't had any issues with latency or dropped packets. AT&T reboot time is still only about 20-30 seconds.
-
Mmm, interesting. Yeah I wouldn't expect the auth to take more than a fraction of a second really. Let's see if anyone else is seeing a delay there.
-
@stephenw10 Just to clear up any confusion, when I said 20-30 total reboot time, that is basically from powered off to a solid green light on the gateway. IP Passthrough mode (essentially bridging) does not add any additional time to the reboot cycle because it's still doing the auth.

@DefenderLLC I understand your sentiment, considering you're still stuck with the gateway using this bypass method. I liked the idea of putting the gateway behind my firewall, but it also made it easier to co-locate my network hardware with an UPS...the ONT is in a weird spot in my house. As a secondary benefit, I've noticed a slight to moderate increase in overall performance.
I've yet to see a speedtest actually reach full gigabit speed, but before the bypass I'd hit around 800Mbit with latency of 15 to 20 ms. After the bypass I'm hitting roughly 920Mbit with 8-10 ms latency. It's minor and surely not noticeable to my dulled senses, but it's measurable.
I haven't accessed the gateway itself since the bypass...Setting it up on a 'modem' interface keeps me from getting at it via the ol' 192.168.1.254, but I may see if I have time to mess around and look into the RG logs if they're easily accessible.

AT&T generally oversubscribes the service, but if you’re using a 1 gig port from the gateway to your LAN of course you’re not going to get any speeds faster than that. Port number 1 (the blue one) is a 5 Gb port on the newer models and will step down to 2.5Gb or 1Gb. Now the ONT modules are built into the modem itself. You have no choice but to use it.
I went back to the one gig service and this is what I get from my UDM-SE which sits behind my Netgate 6100 MAX with IPS enabled on both firewalls (dual NAT).

Hey AT&T folks! I'm new here and do want to be frowned at for double posting. I have a AT&T Pace 5268ac and got the new Bypass to work but every 24 hours for ~90 minutes the modem interface drops and reconnects every 2-3 minutes. If you might know how to help please jump over to my post.
Thanks!

@DefenderLLC would it theoretically be possible if you had a pfSense box that had a fiber input used as WAN? Unless there's a reason someone is using that same certificate type that's using the Ethernet rule. I don't have either but was curious if someone may have tried that option.

You cannot do this with the newer AT&T gateways like BGW320 (newer installs in the past 2 years). The ONT module is built-in to the modem itself and it must be used in conjunction with the SFP+ module that they provide to authenticate the service. There's no getting around it for new AT&T Fiber installs unless they happen to give you an older modem and separate ONT box which would be very rare unless they have no way to get the fiber to the modem directly.

Thanks to C McDonald (@cmcdonald ), there's a new wpa_supplicant out which now listens on vlan0. Netgraph or vlan stripping switches no longer needed.
code
https://reviews.freebsd.org/D40442You can either compile your own or get the binary in this thread on dslr
source - https://github.com/freebsd/freebsd-src/tree/main/contrib/wpa
binary (for 23.05) - https://www.dslreports.com/forum/r33686937-
Future versions of pfsense will come with the new binary.
As this is using wpa_supplicant, certs are still required. Existing wpa_supplicant.conf is still usable.
For implementing, 2 shell command lines are really all that's needed.
earlyshellcmd
/sbin/ifconfig igb0 ether "RG MAC" && /root/wpa_supplicant -B -Dwired -i igb0 -c /root/wpa_supplicant.conf -P/var/run/wpa_supplicant.pid && sleep 10 && /usr/sbin/wpa_cli logonAdjust paths and interface as needed. RG mac should be in the form of "11:22:33:44:55:66". Probably works without the double quotes, but given the sequence contains colons, quotes preferred.
shellcmd
wpa_cli logoff && sleep 10 && wpa_cli logonDon't forget to update the wan interface to reflect correct interface, not ngeth0. Also for now, mac spoofing still in effect, but we're testing if that's really needed.
This sequence should provide a relatively fast boot, without the 60s delay at the "configuring wan interface..." line. The logon commands are there to speed things up. Normally the upstream sends a username request to the gateway (or supplicant in this case) every 30s until a response is received. The login command expedites this.
In testing, wan ip via dhcp was generally obtained right at the end of boot or within a few seconds after.

@GPz1100
The wpa_supplicant.conf is the pfatt.sh correct? Or is there a specific .conf file to get?Thanks
-
@AiC0315 I use the conf that was generated when I extracted the keys
-
@AiC0315 You could use the pfatt script, but will need to modify it to remove all references to netgraph. It applies configuration a bit differently but it's the same values. Also, pf's native dhcp works, so that line too can be commented out.
The command lines I posted earlier are simple enough, don't really see a need for a script. You can add a
-sto enable logging to syslog.wpa_supplicant.conf is the one created with the devicelocksmith tool when generating the certs. You will need to a line early on for wpa_cli to work.
ctrl_interface=DIR=/var/run/wpa_supplicantunder the last comment (#) line.

@GPz1100 Thanks, I bought my certs so I don't have the .conf. I have the 5268. not sure if there is a way to get the certs from that without desoldering?
