we are running a Windows Server 2003 inside a private network. The network is connected via router (NAT) to the public internet. At the server we like to connect some USB dongle for our licensed software. A VPN session to this network or to the server shall be avoided.
On idea is, to open a port forwarding from the public internet to the USB-over-network-server. I assume that in this case that everyone in the public internet can access the dongles who is aware of the forwarded port number. Is there a solution, that to secure the port? For example, only with a password a SSL secured connection is established to the USB-over-netwerk-server.
USB over Network has SSL security option, see here: http://www.fabulatech.com/usb-over-network-server-help/ssl-settings.html
So, you can use your own certificate to protect the data. Feel free to download the trial version on our website to check this functionality: http://www.fabulatech.com/usb-over-network-download.html
some questions, since the steps to establish such a SSL connection are currently not clear for me: a) How to generate a PEM? With openssl? b) On the USB server will install the one certificate (private and public key). Which things I have to install on the computer which accesses the USB-Server? Do I have to create a second certificate? c) Is there anywhere a procedure, which describes how to install such a SSL connection with your USB software?
