Siemens PLC -Uploading and downloading using netPI & VPN

[MGharat]

Hello Armin,

Greetings! what is your suggestion to use Tosibox container? or openVPN? 

we already contacted to Tosibox yesterday & they are planning for us some online demo . Also some free trials are available.

what I understand is with both these , we can get VPN server functionality to our netPI which can be then accesed remotely anywhere by  the VPN client software ---is it correct?
Field PLCs connected to ethernet port of netPI are also accessible remotely for configuration upload/download?

please guide as we have few customer enquirers regarding VPN application.

Thanks & BR
