Arturo, There are several ports you need open at your institution in order to run the IDV so that it may connect to different data servers. In general, ports 112, 8080 and 80 are required. If port 112 is a problem, we are in the planning stages of giving users an option to communicate with ADDE via port 80, but this work is only preliminary so far.
