Hi,

could you elaborate a little more please because it is very vague description.

did you verify you router end had an ip address ? did you verify arp was working correctly?

If you could post "show ip interface brief" and "show run" while plugged in to the WAN that would be helpful.

Hi,

first do this:

no ip route 0.0.0.0 0.0.0.0 FastEthernet0/1/0

ip route 0.0.0.0 0.0.0.0 x.x.x.x  where x.x.x.x is your next-hop IP

Then try to ping 8.8.8.8 and if it is successful but you can't ping the other end it is surely because they filter ICMP.

Alain
