  2. estos UCServer is installed and started.
  3. For a safer use of UCServer Web Services and your internal data (LAN) to protect against unauthorized external access, we recommend setting up a DMZ with a two-stage firewall concept. A schematic representation of the DMZ structure is available in chapter demilitarized zone (DMZ).
  4. Between UCServer Web Services and estos UCServer (default port 7222), a TCP connection can be established. Alternatively, you can check the connection via the estos ProCall.
  5. For using the apps on your mobile devices or ProCall for Mac® outside LAN environment, so you must make sure that the Microsoft® Internet Information Services (IIS) is accessible on the Internet. Refer to the chapter accessible on the internet (demilitarized zone (DMZ). How to configure your router or your firewall accordingly, please contact the manufacturer of the system component.
