I have an Apache server running on Ubuntu server 10, using Passenger for Ruby on Rails. I have configured my site under the sites-enabled directory of Apache and can hit the server with an internal IP address (192.168.X.X) and the site comes back as expected. However, whenever I try to hit the site externally, either through the domain name or the IP address tied to the domain name, the site will not come back. I have a router in the middle with a static IP address, with Port Forwarding turned on (forwarding 80/443) to the server and I'm quite confident the issue isn't there. In fact, I even DMZed to the Ubuntu Server just to make sure. Also, all router firewall options have been turned off. So here is the question...

Is there something else I have to do with Ubuntu server to allow externally requested port 80 traffic? Otherwise, is there some settings that need to be set in Apache to allow domain or external IP address port 80 traffic through?

I'm pretty new to Apache, so, please take it a bit easy on me :-)

Thank you for your responses.
