If InterFormNG2 is running on a remote machine e.g. in the cloud and you want to be able to e.g. print out on local, unreachable printers (because e.g. there is no VPN connection), then you can consider to purchase the remote client module for InterFormNG2.
With that you can install a local remote client on a windows machine in the local network and here allow this client (via open firewall ports) to reach the central InterFormNG2 server.
The remote client is covered in details the section, Remote client.
