Ok, I have been using Arcgis Server for a year now. Recently I viewed a few Flex Viewer apps and really liked how it works. I downloaded, added my basemaps, Street Maps and my own data. It really looks good. However, I can not view it from outside the network. When I try the Viewer comes up and all the widgets are there, just no data or visible maps, blank screen. Any ideas as to what I am doing wrong? It works Great from the local server. Just to remotely. The only file I have changed is the config. Do you have to do anything else?
