WAN PPoE AUTH_TOPEER_FAILED error

rafaelgilardino · November 18, 2021, 7:08pm

Hello folks,

I have recently acquired a DSL Modem (eci b-focus v-2fub/r rev.b) to replace the current modem/router from my ISP.

The ultimate goal is to use my TPLink Archer C7 v5 modded with OpenWRT v21.02.1 (the latest one)

Theoretically it should have had work by just plugin the ECI modem and by configuring the WAN interface of my OpenWRT as PPoE with the provided credential from my ISP.
Unfortunately I'm keeping getting the error AUTH_TOPEER_FAILED

I tried some instructions from the existing threads but also with no success.

Would really appreciate your support to try to fix it

By browsing on my ISP forum some users recommend to use VLAN 101 in order to get connected. Is it something that I should care about? How could I do that?

Below my current configs:

In most cases with VDSL, you have to do VLAN tagging on WAN to connect your ISP.

Thanks @slh

I gave up on my original config and performed a factory reset.

After adding the VLAN (new configs below) the "AUTH_TOPEER_FAILED" vanished however no hint is shown. With some more further investigation I managed to fetch the logs for the PPPoE which now show "Timeout waiting for PADO packets"

Assuming that Vodafone require the VLAN id 101 is my config correctly set?

slh · November 22, 2021, 11:40pm

Disclaimer: I'm not familiar with vodafone UK specifics, so the advice below is generic and more about syntax than semantics.

eth0.101 (although this would be non-fatal, merely just not setting the 'correct' MAC)

config interface 'wan6'
        option device 'eth0.101'
        option proto 'pppoe'
        option username 'dsl002685188@broadband.vodafone.co.uk'
        option password '*********'
        option ipv6 'auto'

I don't think that you need this (two PPPoE sessions), it's possible, but very unlikely - I'd suggest to remove wan6 for the early debugging and going back to that, once you have the basics/ IPv4 working.

config switch_vlan
        option device 'switch0'
        option vlan '2'
        option ports '0t 1t'
        option vid '101'

option vlan '101'

Thanks for the support @slh
Unfortunately even after these suggestions same error

Just to be sure I'm sending a diagram of my current setup

I just recently bought this OpenReach modem in order to get rid of the router from Vodafone UK. The idea was to use it to cover the lack of DSL of my own router

The things that seems most odd to me is that I keep getting the same error message regardless if I keep the router connected to the modem or not

My configs are now like below:
