# Installation of the DMZ adapter
# Requirements
- installed 4App Core Engine (opens new window), version 3.9.3 or higher for the possibility to download
dmz-adapter.zip
. The dmz service supports version 3.6 or higher, though.
# Installation of the 4App
The DMZ adapter is available as a separate 4App (4allportal-dmz-adapter) and can be downloaded and installed via the app management in the administration area. After installation, activate the 4App and restart the system.
You now find new admin snap-in General system configuration/App management/DMZ adapter
in the administration area of your 4ALLPORTAL. The snap-in allows to download the service file.
See the installation and configuration instructions for the web service here.
