Hello,
I have no access to WAN with my cisco 881(Cisco 881 sec K9; IOS 15.0(1)M8). The 881 is in PPPoE
I followed the discussion: https://supportforums.cisco.com/message/3465409#3465409.
I thing my config is almost the same...
But unfortunaly I can't ping 8.8.8.8 i.ex., from the router.
In the PPP log I saw the login with success to ISP and it receives an IP address.
This is my config:
ip source-route

Someone can help me?

Hello Pierre,
Please use "ip address negotiated" under interface dialer instead of using "ip address dhcp client-id FastEthernet4".
Please use " ip mtu 1492" instead of 1452.
Are you getting a valid IP address in the dialer after making those changes?
Regards.

Hello Jose,
Thank you very much, it works.
I tried "ip address negotiated" at starting of config but without success. Probably something else wrong.
