Strange? NAT behavior on cisco 2651
Posted on 2003-03-29
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 22.214.171.124 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?
