Heres my config file, the ubr is gonna be its own internet router. I did have it
 behind a sonic wall router. Figured it was easier this way. Ultimately they 
have a new 2811 that can be used.

I pinged all the ips like you said. They were all good except the 2 public ones.
I need to get past this part. By the time I'm done here Ill be able to pass a CCIE
test! Any help is greatly appreciated and start an invoice. After reading over this 
fourm you guys are top notch pros at this stuff. Best place on the internet for docssis
advice.
                Thanks again    Gary
