Routing in OpenVPN between local networks (Win)

Question

openvpn

Good day, dear friends, I need help in routing between local networks using OpenVPN.
There are 3 networks:
1. 10.6.*.*
2. 10.10*.*.*
3. 172.*.*.*
There is a media server in the 10.6.*.* network, all networks have access to it via their own optical channels, at this point in time between 10.6.*.* and 172.*.*.*, the optical link is partially out of order, and access to the server is difficult.
To solve the problem, it was decided to launch the OpenVPN server, which will be located on the 10.10*.*.* network , the optical channel of which is operating normally from 10.6.*.* .
The question arose, how can clients from 172.*.*.* get through the OpenVPN server 10.10*.*.* , to the media server 10.6.*.* ?
After the initial setup, clients from 172.*.*.* receive from the OpenVPN server 10.10*.*.* , ip addresses like 10.8.*.* .

Answer 1

if there are 3 interfaces on the OpenVPN server, one from each network?

Answer 2

@tottl Please describe the hardware topology of your network

Answer 3

On the OpenVPN server, only 10.10*.*.* , which has access to the other two, via separate optical channels.

Answer 4

I can’t write this to you, because I don’t personally know it myself, I know for sure that the network is divided into s* segments , that is, 10.6.s*.* , I think it’s not important for you to know the number of segments, and each segment is connected naturally in the main server room, and already in the server room itself (main), an optical channel with other networks.
OpenVPN is the only option that we see at the moment, since physical access to the media server is required, a temporary solution is now ccproxy, to view content on the server.

Answer 5

Try to register on one client (as a test) in cmd as administrator route add 10.6.0.0 mask (network mask) 10.10.*.* (gateway address on this network, which one you have there, 10.10.0.1 or which one, I think figure it out). The only thing I can't understand is why OpenVPN is here. oh well, try
