Thanks, Charlie. I had someone else test it from an external site and it is working. Since I was using the external address I just assumed it would forward, but did realize that DNS is actually resolving it to the internal network.
Another Port Forwarding question: I want to run a web server on a different machine, the project I am working on will eventually be moved to a machine that won't be an SME Server. Can I forward all traffice on port 80 for a domain to a different machine? Or is there a better way?
Thanks,
