Well, I think I understand pretty well now, how is SHOULD work. Alas, its still not working. I've set my internal IP to static at 192.168.1.104. I figured out how to access my router, and set the port range 20-20 to forward to 192.168.1.104 for the application "filemaker". My database is open on that computer. Network Sharing is turned on.
Using Safari I type in http://192.168.1.104 but I cannot connect so what do I need to change there?
Second:
I open IWP settings. The URL is already there for me and I cannot change it. It says http://192.168.1.104:20 but this is my internal IP. Where or how do I tell it my external IP?
thanks for all your help!
