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:

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.
