Good morning,
Please I have a router 2901, which I configured tow sub-interfaces for Voice and Data. Everything seems to be working fine but I can't access the internet after configuring NAT.

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for one-time use. If you hav
already used the username "cisco" to login to the router and your IOS imag
supports the "one-time" user option, then this username has already expire
You will not be able to login to the router with this username after you e
this session.
It is strongly suggested that you create a new username with a privilege l
of 15 using the following command.
username <myuser> privilege 15 secret 0 <mypassword>
Replace <myuser> and <mypassword> with the username and password you want
use.

Thanks Dragan llic,
It worked fine, I also enabled nat on the sub_interface
07-03-2014 01:15 AM
Can you change the interface to outside interface in this command
ip nat inside source list LAN_NAT_POLICY interface GigabitEthernet0/1.1 ov
can you try this below command
ip nat inside source list LAN_NAT_POLICY interface GigabitEthernet0/0 ov
