I have a 2600 Cisco Router attached to a Cisco 871 that belongs to Cable Vision with a block of 5 public static IP addresses. I chose one of the open IP addresses to run my Cisco lab without success. I can ping the public IP address from my laptop cannot get online. I was told that I needed to Nat from private to public but when I do I still cannot get online. I was also told that from my personal 2600 to the 871 I should be going from Nat inside to nat outside. However, this still fails. What am I missing?
