Issues on restricted network enviroment

Hi, i am using sentinel-1a data for monitoring enviromental protected areas, however, our company network enviroment is highly restricted and we have to give the list of the sites that have permission to access e to do donwload, so many features of the SNAP for the sentinel are blocked (Automatic downloads of Aplly-Orbit-File, Terrain-Correction and so on…). Can you provide us a list of the sites (internet address or ip or etc) that the SNAP uses so we can solicitate the access in the network?

Thanks in advance

Several sites can be found in the file It is located in the etc folder of the installation directory.
Maybe this are already all you need.
