I’m fairly new to the DSC module. I have successfully established a tag server and read the tag values from a client pc. My application needs to have a tag server on a remote site so there the internet access can only be done using a gprs modem. So, now using exactly the same program as before I can’t connect to the server (internet access trough gprs modem). My guess is that the ports that the server needs to work are closed for outside use (that’s why it worked with 2 pc from inside the network).
Does anybody know exactly which ports need to be open in order for the application to work? so I can tell the company’s networking people to open them.
