Using OpenVPN without Router Configuration

JoRu1407

Hello guys,

we need to built up a remote maintenance solution for our PLCs.
As VPN Client we'd like to use OpenVPN on a mini XP computer and we're going to built up an own network for each machine.

Now, our problem is, that we can't change any router or firewall settings in the companies where ourch machines are used.
So...Is there any possibility to setup OpenVPN (maybe with an external server) without portforwarding or something?
Essentially I'm trying to use OpenVPN like TeamViewer - There're no portforwardings required...

Many thanks in advance,
Joshua

hi there,

you can setup the server side in your office (port forwarding IS needed)
then setup your PLCs as clients (outgoing traffic no port forwarding necessary..)
you can access your clients via your server,or from another client (client-to-client).

regards.

Michael.

Hello Michael,

that's a really good idea :-D

Would it also be possible to run an own linux server in the WWW and install the OpenVPN Server on it?
Because there would be the advance that I could access to the PLCs from the whole world without waiting on my slow internet access at home...

Do you know if OpenVPN does have some interface to connect it with a own C# app?
