Hello @phanthomias and @Mooperd1,

which router do you use?

The authentication use PPPoE with chap but mostly pap is also configured.

The static IP is assigned dynamically. The Telekom uses 2 different credentials types. (Telekom/T-Online Kennung like yours with Anschlusskennung, Zugangsnummer,.... the other kind is a "Business Kennung" there you have "Benutzername" and "Passwort")

See the following lines from a Cisco router for more information.

"Telekom Kennung" (new) without feste-ipX/ as prefix

ppp chap hostname AAAAAAAAAAAABBBBBBBBBBBB#CCCC@t-online.de
ppp chap password 0 DDDDDDDD
ppp pap sent-username AAAAAAAAAAAABBBBBBBBBBBB#CCCC@t-online.de password 0 DDDDDDDD


"Business Kennung" (old) with prefix
 ppp chap hostname feste-ipX/benutzername@t-online-com.de
 ppp chap password 0 123456
 ppp pap sent-username feste-ipX/benutzername@t-online-com.de password 0 123456

Depending on the connection (VDSL, BNG ) it may be necessary to set a VLAN-Tag at the WAN interface.

interface Ethernet0.7
encapsulation dot1Q 7
pppoe enable
pppoe-client dial-pool-number 1

Maybe this information from a Juniper Router helps.

Telekom/T-Online
pp0 unit 0 {
      ppp-options chap {
          default-chap-secret DDDDDDDD;
          local-name "AAAAAAAAAAAABBBBBBBBBBBB#CCCC@t-online.de";
          passive;
      }
 ...

Business:
pp0 unit 0 {
      ppp-options chap {
          default-chap-secret 123456;
          local-name "feste-ipX/benutzername@t-online-com.de";
          passive;
      }
 ...

Feel free to ask if you have any questions.

With best regards,

I am Mooperd1. I got locked out of my account

Anyway, Thanks for your help both!

We have a Juniper SRX110 here. We got it working with the following configuration. Please note that the default-chap-secret should not be in plain text.

Hi everybody,

thanks for the contributions @andrew.holway, @Mooperd1, @PatrickKnott and @phanthomias.

If you use the collective DeutschlandLAN IP Voice / Data S Premium with the fixed IP-address , you must enable this in the Customer Center .

The identification in the system remains unchanged . Please refer to the pictures .

Could I help you? I am pleased about an answer .

Best regards

Yalcin A.
