Strange? NAT behavior on cisco 2651

I'm running 2 private networks(192.168.2.x and 192.168.3.x) off of a cisco 2651 with two ethernet interfaces. I have a full T1 to the internet. I'm using NAT and all works fine - unless I try and access one of my public IP addresses from one of the private networks. In other words, my web server is 192.168.3.11. My public ip of 141.155.200.190 is mapped to that address. It works fine from the outside. On the inside, if I enter the public IP into a web browser on the internal network I get nothing. If DNS (on my ISP) is used to resolve a my domain to the public address, then it works fine from inside. A straight public IP just doesn't work from inside. Any thoughts?

Thanks for your quick answer. I suspected something like that, but wasn't sure. I'm attempting to access a video file on my internal web server. The calling page is actually hosted externally on a Verizon server. I'm not sure why a direct IP request from an external web page should fail, but I assume it's because the page gets loaded onto my client (internally) before the request for the video file is made (using the external IP). At least now that I know it's not suppoed to work how I was trying to make it work I can focus on making it work some other way...

Thanks
