fa/3 client plugged in client using ip 10.1.0.18 default gw 10.1.0.1 from the router I can ping 8.8.8.8 from the client I can ping 10.1.0.1 70.80.90.99 but not 70.80.90.100 or any external ip.
show nat translations is blank
from the 6509 i set up vlan99 with the external ip defaut route to that interface and same results. I do not have any routing protocols enabled yet on either.

ip default-gateway 70.80.90.100on your router. You have a default route set. You only use the default gateway if you aren't routing. Also, are you absolutely sure that the default route should be to70.80.90.100? That seems unlikely; You should try to just point the default route to the interface without the specific address.
