I should have been more clear. This is a web based (XML) application that needs to be available via "anonymous log in". I began the debug routine by attempting to hit the machine (from the machine) using "localhost". This worked (displayed the XML page in the browser). The next step was to replace the "localhost" with the outside IP address as verified via "whatismyip". This failed. I was attempting to hit again from the local machine but using the outside IP. I then attempted to hit the IIS from an outside server but this too failed. The last step was to ping the server ("ping http://98.254.14.208/cvMail/ccxmlstart.xml". This failed but I suspect that I an pinging incorrectly.
IIS: 7, OS Windows 7 (Home Premium), Netgear router (hardwired in); open port 80 (http) on the router.
