no proxy arp on your router has nothing to do with it, the proxy arp is done by the redback, you 
have to make sure that your route is not pointing to the bvi without next hop, and that there is a 
right default route from dhcp.

Is there any configured static route in the configuration like "ip route bvi1"?

I don't have the exact command in mind, but there is a command at "show ip dhcp" or "show dhcp" 
where you can see what settings you got from the provider dhcp server.

I added "no ip proxy-arp" under BVI1 and rebooted the router to clear all the entries in the arp 
table and right away as soon as the circuit came up and i logged in I'm still seeing the same 
random MAC's and alot of them even though its only up a few minutes.

To keep email from getting too long I've posted debug info

Hi Chris

Is there any configured default route on the router?Is it possible to post output of sh ip 
route?This looks like a default route without next hop ip and proxy arp at the provider...

Kind regardsKarsten
