To be able to access the UTM via SSL VPN, you must configure your remote client. To do so, access the UTM User Portal with a browser on the remote client. There, the necessary installation instructions, software and/or configuration files are available for download.
For remote computers, the SSL VPN client software including configuration is available. The client software has to be installed once for the remote client to be able to connect.
For iOS or Android devices, a VPN configuration is available that can be installed on an OpenVPN software.
