Dst-Nat Inaccessable From Inside

I have two routers set up as follows:

(cloud) <-> Router1 <-> Router2 <-> Web Server

Router1 uses NAT Masqurading for outgoing internet traffic. It also uses Dst-Nat to forward all traffic for a particular IP address to my Web Server.

There is nothing special about Router2, except that it routes between Router1 and my Web Server. All outgoing traffic works fine. All incoming traffic works fine. Here is my problem.

Say that my fixed public IP address I'm using is 1.1.1.1, and that my Web Server is 10.0.0.1. When I enter 10.0.0.1 from another host inside my network, the web server works fine. When I enter 1.1.1.1 from a host on the cloud, it works fine. However, when I enter 1.1.1.1 from a host inside my network, it doesn't work. No response. I want to be able to have employees enter our domain name "mycompany.com" from both out network and from anywhere on the Internet, and the DNS name points to our public IP address 1.1.1.1. Any ideas why it's doing this?

I'm not sure if this is a symptom, but when when I ping 1.1.1.1 from inside my network, I get replies from 10.0.0.1...?

Thanks!
