@Nomcon

config interface 'wan'
        option device 'dsl0.7'
        option proto 'pppoe'

You'll need to add this in your wan section sooner or later:

option password 'xxxxxxxx'
option username 'xxxxxxxxxxxxxxxxxxxx#0001@t-online.de'

and remove this whole part:

@Nomcon

config device
        option type '8021q'
        option ifname 'dsl0'
        option vid '7'
        option name 'dsl0.7'

My configuration works really fine on DTAG VDSL.
