Question:
I have no
access to WAN with my WS-C3750X-12S-S Price 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:

Answer:
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 WS-C3750V2-48PS-S in the dialer after making those changes?
