|This works inside our network by browsing to the inside ip but I am trying to set it up to work outside of our network.|
If it's working internally you've got the issue half way fixed. The problem now is to get to that web page from an external source.
If you're using a SOHO router at work, you'd have to setup a port forward on it. Since it's a web page, you could use port 80. In the router's management interface, find the port forward section and set it up to forward port 80 to the LAN IP of the box that contains that resource.
If you don't have a SOHO Router, then your firewall would have to be set to handle the redirection to the internal resource.
Without knowing a little more about your setup, it's hard to be of any more help.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
