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] LCP: Down event
2023-03-01T20:27:09 Informational ppp [opt2_link0] Link: DOWN event
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  :D

//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.
i want all services to run with wirespeed and therefore run this dedicated hardware configuration:

AMD Ryzen 7 9700x
ASUS Pro B650M-CT-CSM
64GB DDR5 ECC (2x KSM56E46BD8KM-32HA)
Intel XL710-BM1
Intel i350-T4
2x SSD with ZFS mirror
PiKVM for remote maintenance

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)

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 :D

thanks for the help and br
