Cisco 881 WAN issue

pierreculot

Level 1

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

!

!

ip dhcp excluded-address 192.168.9.1 192.168.9.99

!

ip dhcp pool ccp-pool1

   import all

Gateway of last resort is 0.0.0.0 to network 0.0.0.0

S*    0.0.0.0/0 is directly connected, Dialer0

      192.168.9.0/24 is variably subnetted, 2 subnets, 2 masks

C        192.168.9.0/24 is directly connected, Vlan1

L        192.168.9.1/32 is directly connected, Vlan1

Someone can help me?

Thank you.

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.
