            ^^^^
Since eth1 is your DSL ethernet device, make that BOOTPROTO=none
or delete the profile for eth1 completely.

Here you do not even reach the access concentrator which can be due
to bad wiring between your PC and your T-DSL modem, a misconfigured

Telekom's broadband point of presence (1&1 Internet doesn't use
T-DSL ZISP). What do you get for...?
