Hey, 

I have troubles to connect the internet from the router and the clients behind. The pppoe connection seems to be established, I got an ip address but no internet connection.  Need help! 

My configuration (ISR1100-6G):

service call-home
platform qfp utilization monitor load 80

3 - CWA is a default route for Central Web Authenication - WLC --> nothing to worry about.

even when i shut and no shut the interface. I will get this gateway/route. You can see that in the debug

Ping again after remove ip nat outside from GigabitEthernet0/0/0.7

MHM

 

still not working..

R#show ppp interface virtual-access x

check the DNS you get from ISP and ping it 
it can ISP have policy drop request to 8.8.8.8

MHM 

Hello,

who is your ISP ? You are using Vlan 7 for the ISP connection, is there a reason for that ?

interface GigabitEthernet0/0/0.7
encapsulation dot1Q 7
ip nat outside
pppoe enable group global
pppoe-client dial-pool-number 1

it is Telekom (Germany) and vlan 7 is mandetory

Hello,

thanks for the info. Telekom indeed requires Vlan 7. I don't know if you understand German, or if you are in Germany, but the problem might be with authentication. I can translate the below if need be:

Protocol: PPPoE
PAP/CHAP username: AnschlusskennungZugangsnummerMitbenutzernummer@t-online.de
PAP/CHAP password: Zugangskenntwort

If your access code (Zugangsnummer) has less than 12 digits, read the below:

https://telekomhilft.telekom.de/t5/Festnetz-Internet/PPPOE-Einwahl-ueber-einen-Router-herstellen/ta-p/3654990

I’m in Germany and understand german as well. the pppoe session is established in my point of view. I would not get an ip address and the pppoe authentication debug (from the beginning) is successful. 

Hello,

that's right. I just mentioned it to be sure. At this point, I would erase the entire config (wr erase), reload the router, and start from scratch with just the bare, basic config below. Something is interfering.

i was thinking about that too. So I've done that, but still no connection to the internet. 

 

Hello,

utterly annoying indeed. Which public IP address are you getting ? I want to test if I can ping that address...

EDIT: Since you use IPCP for the default route, try and remove the static default route, which is not needed:

--> no ip route 0.0.0.0 0.0.0.0 Dialer1
