(flint 2) PPPoE Unable to complete PPPoE Discovery

Greetings,

I got flint 2 recently, and I tried to connect PPPoE however, it does not work.

Specs:

  1. Network Setup: ONT that provides ethernet cable, and the ONT is connected to a fiber cable.
  2. router model: flint 2 MT6000.
  3. from the box firmware version : 4.5.6
  4. from the box OpenWrt Version: OpenWrt 23.05-SNAPSHOT r23001+721.
  5. from the box Kernel version: 5.15.139
  6. Using pre-installed OpenWrt from GL.iNet.
  7. I have upgraded the firmware to: 4.5.8 I downloaded it from the stable tab and then applied the upgrade from System -> Upgrade -> Local Upgrade tab and used the default config "Keep Settings" is ON as i'm unsure if I need to disable this or not.
  8. OpenWrt Version after firmware update: OpenWrt 21.02-SNAPSHOT r15812+1071.
  9. Kernel Version after firmware update: 5.4.238.
  10. before the upgrade I tried PPPoE using the default firmware version, however it only showed first log Unable to complete PPPoE Discovery.

Please note that I updated the firmware because in some replies I found on this forum that when the upgraded the firmware PPPoE worked fine.

in order to have PPPoE connect I found that I need:

  1. username/password PPPoE.
  2. maybe a VLAN id.
  3. maybe I need to try enabling ipv6 and check.
  4. maybe changing the router MAC address to the same ISP router MAC address (I don't know how I can do this).

So, I got the username/password and VLAN id from the provided router by the ISP.
Here's what I got when connecting the ethernet from ONT ethernet to the router in WAN interface:

Timeout waiting for PADS packets
Unable to complete PPPoE Discovery
Exit.
Plugin rp-pppoe.so loaded.
RP-PPPoE plugin version 3.8p compiled against pppd 2.4.8
pppd 2.4.8 started by root, uid 0

and then when I enabled IPv6 NAT6 the logs changed however, after I tried changing the IPv6 from NAT6 to Native the previous log returned back and then I never got the following log again:

Connection terminated.
Sent PADT
Exit.
Plugin rp-pppoe.so loaded.
RP-PPPoE plugin version 3.8p compiled against pppd 2.4.8
pppd 2.4.8 started by root, uid 0

Please I need your support.

Could you please paste the whole system log?
You can find it in System > Log

Dear rain,

I will send it to you 1-1 later. I need to retry the PPPoE process.
As I have ran "System -> Reset Firmware" process.

Dear rain,

Kindly check your messages.

Thank you I was able to solve it. I had to change some stuff from the advanced settings.
Regards.

Can you please add which advanced settings you changed?
