Hey,
I have problems using the Turris Omnia on my Vodafone DSL connection.
Setup:
I am using the Turris Omnia with the Draytec Vigor167 as Modem.
Problem description:
I got different credentials for a dynamic ip and for the static ip. It does work on the turris omnia with the credentials for the dynamic IP (at least for IPv4), but it doesn’t work with the credentials for the static IP.
What I tried:
I also tried it with the FritzBox Router which was provided to me by Vodafone and here the static IP does work, so the credentials seam to be all right.
I tried to use the FritzBox with the Draytec as modem, to make sure this isn’t somehow the issue, and that worked as well.
Configuring the MAC-Adress of the FritzBox at the turris omnia didn’t help either.
Log File:
Here is what I think is the relevant part of the log file. If you need anything else, please let me know.

Are you sure VLAN 7 is correct? This is usually the case with Deutsche Telekom lines or reseller contracts that use Deutsche Telekom lines. With a Vodafone connection, you may need to enter something different here.
Yes, that is definitely correct. It’s a Telekom line, VLAN Tag 7 works with the credentials for the dynamic IP, the FritzBox uses this as well, and I tried 132 (the ones for Vodafone Lines) as well and it didn’t work.
Mmmh, I remember I had to check the “force link” checkbox in the advanced options for pppoe-wan (not exactly sure where)… But the issue here is “No response to 5 echo-requests” which might mean things are not as they should and your client might not reach the pppoe server, or the server does not do keep alive heartbeat packets…
I tried it with “force link” set to true as well, but that didn’t help.
And regarding the No response to echo requests: Like I said, it does work with another router (the fritz.box), so there must be an (configuration) issue on the turris omnia side.
Well, who knows FritzOS might not set up a 5 echo-request threshold… I think under luci you can configure this, also if you have not already, edit /etc/ppp/options to enable debug output and potentially also a specific pppoe logfile, this might give you more clues…, also take a packet capture to see what packets come in from the pppoe server…
I am not doubting your report that the FB works out of the box…
Thanks, for the hints on how to debug this, that was helpfull!
I enabled debug output, and in the log it seems that, for some reason, the CHAP authentication is not successfull. So it is not about the echo requests. However, the credentials are the same as on the fritzbox, for sure. I even tested the CHAP challenge/response with hashcat against the correct password to sure if something is wrong there, but hashcat confirms that the challenge/response is for the correct password. So I don’t know why the authentication is not successfull than… Any idea?

With the credentials for the dynamic ip, I get a succuess response:
Strangely when I try it with the fritzbox, it sometimes doesn’t work directly either. The fritzbox reports timeouts in PPPoE. But after waiting a bit, restarting, etc. it works.
Still possible that the process simply takes longer than the 5 LCP echo request and while the PPPoE server is still meddling with your CHAP data your OpenWrt router hangs up, since it did not get anything back from the server for longer than the permitted time-out…
Really just for the fun of it try to disable the echo requests or set them for a considerably higher timeout.
Okay, that did actually help. But, if I understand it correctly, not because the CHAP server takes that long. But because now the connection is not disconnected before it tries the CHAP authentication with a different Name. Don’t really know a lot about this, but this still doesn’t seem like it should be this way.
However, there still is an issue: The connection resets every minute. Don’t know if it does that because of the timeout in sending the IPv6 config-request… But this also means that while IPv4 is temporarily working, IPv6 isn’t.

Adding that with the credentials for the dynamic connection, IPv6 also times out, but the connection does not reset every minute.
When disabling IPv6 it is the same as well. My ISP does support IPv6, and I want it enabled as well.
I do get errors from odhcp6c:
odhcp6c[16857]: Failed to send RS (Permission denied)
odhcp6c[16857]: Failed to send SOLICIT message to ff02::1:2 (Permission denied)
I did read somewhere, that ip -6 route add default dev pppoe-wan resolves the Permission denied error, which it does (not permanent that way). However, it still fails with (Address not available) afterwards.
