Networking Guru - Help me! I'm trying to set up a neat little program called Subsonic. I have it running on Apache Tomcat on port 7000 at the moment. I can do a [http://localhost:8080/subsonic] and it works fine from the host computer. I can do a [http://192.168.1.Blah:8080/subsonic] (the hosts IP) and it works fine from both the host computer and my fiance's computer (which is inside the network). I can do a [http://10.Blah.Blah.Blah:8080/subsonic] (my router's external IP) and it works fine from the host computer and my fiance's computer. But no one can access it outside of my network. I've even tried bypassing my router completely and just hooking the host up directly to the cable modem (thus, the host has the 10.Blah.Blah.Blah IP that my router would usually have). Still a no go. To make matters more complex, WhatIsMyIP.com reports a completely different IP for me than my computer lists for itself (when connected directly to the cable modem), so there must be another layer above even that. Here's a diagram of the situation. If I'm at my work computer, how do I access the WebApp on my home computer?
