You can't use NOARP on a normal network interface without some static neighbor
entries.  PPP interfaces do not require ARP since they are point-to-point
and you already know everything about the destination.  For ethernet interfaces,
you need arp to resolve the IP to MAC address mappings.

Get rid of NOARP in you eth0 case, and it should work.
