I have developed a website on our LAN that I am able to access internally using the servers name/IP address (192.168.0.3). However, I am not able to access the website externally from other locations. I am convinced that I have something wrong in the Cisco PIX 506E firewall but am unable to figure out what it is. I don't have any Cisco credentials and only know how to change the settings using the PDM console.
Under "Access Rules" I have created a rule to Allow, Source: Any, Destination: 192.168.0.3, Interface: outside, Service: http/tcp.
Under "Translation Rules" I have created a rule: (Original) Interface: inside, Address 192.168.0.3 Port 80/TCP, (Translated) Interface: Outside, Address: Interface IP Port 80/TCP.
Both of these rules are setup identically (other than port numbers) to the rules I successfully setup for FTP and for Remote Desktop forwarding so I really can't understand why this isn't working.
I can open the website internally by entering: http://192.168.0.3/homepage.html
I can not open the website externally by entering: http://
<external IP address>/homepage.html, I get the standard error message "Internet Explorer cannot display the webpage" in my browser window.
I have tried Firefox as well to eliminate the possibility of it being a browser issue.
I'm not worried or concerned about DNS, I'm simply using the static external IP address.
Thanks in advance for you suggestions,
