[Solved] Turris Omnia and Deutsche Telekom All-IP

This entry has two purposes:
To help others when they encounter the same problem
To propose an extension to the Turris Omnia web interface

  1. Problem and Solution
    Yesterday, my old phone line (Germany: ISDN + ADSL+) was changed to an All-IP-line. After the change, my modem (Allnet ALL0333CJ) showed a green LED for “DSL ok”, Ethernet to the Omnia was ok, but I had no connection. Checking “/var/log/messages”, I found lines about a “PADO timeout” and retries about once per minute.
    Need I say that Telekom customer service had no clue? They tried to shift the blame to me and declared the Omnia as “incompatible” (which I strongly doubted).
    Checking the internet, my son discovered reports of a VLAN tag 7 added by Telekom and also a way to set that in the Omnia. This is the patch:

        option proto 'pppoe'
  2. Turris Omnia web interface
    I did not find a way to display or set VLAN tags on the Omnia’s ethernet ports.
    Given that Deutsche Telekom enforces their use, I propose such a way should be added.

This can be set in Luci -> Network -> Interfaces -> WAN. There you can set protocol (e.g. pppoe). Under „Physical settings“ you can set vlan (e.g. eth1.7)

sadly this works only on the 3.x.x tree of TurrisOS. I tried on 4.0.1, but it does not worked.

Did you notice that WAN port changed from eth1 to eth2 in Turris OS 4?
