OpenVPN Support Forum

Hi,

I have the following to do but i am not sure how to configure this with openVPN.
I have 20 measuring devices which are located in different networks. All this networks have the same ip structure.
Network A: Device 172.16.0.200
Router 172.16.0.1
Network B: Device 172.16.0.200
Router 172.16.0.1
Network C: Device 172.16.0.200
Router 172.16.0.1

Each of this router accept OpenVPN calls and I want to connect over an internal transfer network all devices on the same time.
The software for theses devices requires a direct ftp access.
I think we need a NAT router or similar for this situation:
Example Network A
Server Internal – Gateway – Router to the OpenVPNNetwork – Tunnel to Network A – connecting to device NW A
192.168.0.2 – 192.168.0.1 – 192.168.0.(1) – mapping IP Device Network A to IP w.x.y.z – 172.16.0.200
Example Network B
Server Internal – Gateway – Router to the OpenVPNNetwork – Tunnel to Network A – connecting to device NW A
192.168.0.2 – 192.168.0.1 – 192.168.0.(1) – mapping IP Device Network A to IP w.x.y.z+1 – 172.16.0.200

Could you understand my problem?

I can explain more if it is required.

this is more a NATting issue than an openvpn issue; if you can set up an OpenVPN connection to each router and assign a unique (VPN-space) IP Address then with the right NATting rules you can address each device.

Sorry for my late answer, i thought, that i get an email if someone answers on my question. I don't have clicked "notify me".

First this sounds good, but how can i setup a unique VPN-Space inside the config file. If i google VPN-Space i got no good information.

Today my config file on the client which i use for dialing looks like this:
If i will let a server to handle all connections i will use a Linux system but i have to make sure that 192.168.10.1 is very time Site001.
or have i add many virtual lan adapters and use a small script which says eth0.1 is site001, eth0.2 is site002.?
