[SOLVED] VDSL PPPoE Telekom Error

[chiwou]

Hello,

currently on
Versions OPNsense 23.1.1_2-amd64
FreeBSD 13.1-RELEASE-p6
OpenSSL 1.1.1t 7 Feb 2023

and a few days ago, my VDSL connection suddenly stopped working

VDSL
German ISP Telekom (T-Online) with PPPoE
and a Zyxel VDSL Modem

I tried recreating the interface, test the modem etc.
PPPoE connection with a Notebook behind the modem is fine.

here is the PPP Log

Code: [Select]

2023-03-01T20:27:10 Informational ppp [opt2_link0] PPPoE: Connecting to ''
2023-03-01T20:27:10 Informational ppp [opt2_link0] Link: reconnection attempt 5
2023-03-01T20:27:09 Informational ppp [opt2_link0] Link: reconnection attempt 5 in 1 seconds

2023-03-01T20:27:09 Informational ppp [opt2_link0] PPPoE connection timeout after 9 seconds
and this keeps happening


Any ideas? Read a few threads about PPPoE, but these were for IPv6, so one problem at a time 

//Update
Even on a new installation the problem persists, don't know what to do

just for giggles, installed pfSense today, and had no issues connecting via PPPoE

should I open a ticket on the OPNsense Github?

yes

do you have vlan 7 configured as a parent interface for your dialer?
LCP error looks like there is no l2 connection to the provider bng. mostly caused by a missing vlan tag.

FYI: the default vlan can be configured on the modem.

But I did reset the modem and created a VLAN 7 interface and connect the PPPoE over the VLAN, no luck.

Got a new speedport today, set it to modem mode, but still the same result (with and without VLAN 7)

did create an issue
https://github.com/opnsense/core/issues/6408

[chiwou]

after some trial and error, could narrow it down to the ports on my appliance

switched the ports, since I did this for pfSense and now it's working on OPNsense as well.
also closed the issue on github.

maybe it can help someone in the future, if there is also a weird error like mine

thanks for the help and br
