After receiving it, you can find GlobalProtect’s official documentation here.
Put simply, download the package, untar it, and install the correct package with apt or yum. It will be something similar to “GlobalProtect_UI_rpm-X.X.X.X-XX.rpm” if using RHEL, or if using Debian/Ubuntu it will be similar to “”GlobalProtect_UI_deb-X.X.X.X-XX.deb”. If you need further help, please contact us.
