That's actually common on DIA circuits with some companies. I know AT&T does this for their customers. It's an added layer of protection to make it harder to attack the router, especially if you're running BGP. It might be a default with Megapath as well. Best to ask them.

The issue I have is, there's no connectivity from the router itself. Anything behind the router - using the LAN IP block - works fine. For example, within the Cisco CLI, if I issue the ping command by itself, I get no reply. If I issue the ping command & specify that the source address is the IP on the FastE interface, then I get replies. Is something fundamentally wrong with my config? Or is this simply the result of Megapath provisioning? If so, is there a simple way to workaround the issue? Such as making ALL traffic from the router appear to originate from the IP on the FastE interface. Thanks in advance for your help/replies.
