Did you find a solution to your problem? I use a Vigor 130 as an ADSL modem and it works fine some weeks without problems. Since a change at my provider “1und1” I have the same error messages with PPPoE and I get no more connection.
If your 1und1 line is switched to DTAG’s BNG you will have to use VLAN tag 7 on the line, as otherwise no connection to the ppp server… (and yes that is a change, on the BRAS platform ADSL lines did not need to use VLAN7). This might or might not be your problem, I seem to recall there a specific firmware versions for the vigor130 that will either pass through VLAN tags or will even add VLAN seven to traffic passing through specific LAN ports. But google should help if the VLAN tag is your issue…
