Cisco 876 - T-DSL Business

Hallo,

ich bekomme einfache keine DSL-Verbindung zustande.
Die Lämpchen bei OK, CD und PPP leuchten ständig grün am Router, aber kein blinken bei RXD ADSL oder TXD.

Wenn ich einen Connection Test mache, bekomme ich folgende Meldung:
Checking interface status: up
Checking for DNS settings: Failed
DNS configuration check has failed. No DNS Lookup has been configured.
Configure the command 'ip domain-lookup' in the config mode on the router.

Wenn ich dann unter DHCP -> DNS -> Primary DNS einen Eintrag mache
z.B.: 194.25.0.68oder 194.25.0.60 (DNS von Telekom), dann kommt folgende Meldung:
Checking interface status: up
interface physical status : up
Line protocol status: up

Checking for DNS settings: successful
DNS lookup set: Yes
Statically configured DNS servers: none
Dynamically imported DNS servers: 194.25.0.68 194.25.0.60

Checking interface IP address: successful
Interface IP adress: 79.207.168.151
Interface IP address Type: Negotiated

Checking exit interface: Failed
Exit interface found: None
Exit interface found: None

To test connectivity, SDM tries to ping the configured DNS servers. However, there is no configured route to any of the DNS servers through the selected interface.
Select 'User-specified' option or add a 'host specific/network specific/default' route through this interface and reset connection.

Ist das mit den DNS-Adressen überhaupt richtig?
Was mache ich falsch?

hier meine aktuelle Konfiguration (ohne DNS settings):

Wie sind Deine Schnittstellen eigentlich mit einander verheiratet, nur die halbe Konfiguration gepostet?
