I have a CISCO 867VAE-K9 router running on IOS version 15.1. I have setup the PPP settings and tested that and it works, I able to ping the ISP DNS servers and also check the diagnostic for a successful ppp connection. The problem is with the internal routing, the router has an internal 5 LAN Ports, and when I connect a device on it, I can’t ping the router (gateway). Here is what I get when I run an interface brief:

Interface            IP-Address        OK?      Method Status   Protocol

ATM0    unassigned        YES     NVRAM            down     down
“This is ok it comes up when I connect the DSL”
Dialer1  unassigned        YES     NVRAM            up         up
Ethernet0          xx.xx.xx.xxx     YES     NVRAM            down     down  
“Don’t know why it’s DOWN this is probably the root error”
FastEthernet0    unassigned        YES     unset    down     down
FastEthernet1    unassigned        YES     unset    down     down
FastEthernet2    unassigned        YES     unset    down     down
FastEthernet3    unassigned        YES     unset    down     down
GigabitEthernet0            unassigned        YES     unset    down     down
GigabitEthernet1            unassigned        YES     NVRAM            administratively  down     down
NVI0     unassigned        YES     unset    administratively  down     down
Vlan1    unassigned        YES     unset    down     down

Here is my Config (again the PPP settings are working), please take a look and let me if you can see what am missing here, it seems to me like a routing issue. The goal is to have FastEthernet0 communicate out to the internet but right now it can not even pint the router (Ethernet0) maybe I need a VLAN but I don’t know:

Note: The Public IP is a random IP not an actual IP but the Netmask is correct
