Question : Cisco config

I am trying to setup a cisco 1700 series router to be used with dsl service.  The configuration i have set up is not passing any traffic. I keep getting a no DNS server are routable through this interface error.  My current config is as followed

interface Null0
 no ip unreachables
!
interface Ethernet0
 description $ETH-LAN$
 ip address 64.190.49.178 255.255.255.252
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 no ip route-cache
 full-duplex
!
interface FastEthernet0
 description $FW_INSIDE$
 ip address dhcp
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 no ip route-cache
 speed auto
 full-duplex

end


The only other thing is we have a wireless router set up as the DHCP server could that be causing the error?

Answer : Cisco config

Sorry for the typo in my previous post.  The wrong interface is being used for the "NAT overload".
  Run these commands *in this order*:
no ip nat inside source list 101 int f0 overload
ip nat inside source list 101 int e0 overload
