Question

Hello,everyone,

we want to build an OpenVpn network to reach our decentralized automation networks. 

We have the following network structure. 

The RUT955 are connected to the Internet via LTE. We have created the clients in the server and loaded them into the routers.

The RUT955 are connected to the OpenVpn AS server.

The task: The subnets of the routers should be able to reach each other via the server. 

The service desk should be able to reach the subnets via the server. 

Our problem: We cannot reach the RUT955 routers via the service desk and the subnets do not see each other.

 We are new in this topic . Since we have been working on it for many hours and the problem has not been solved, we wanted to ask the community. 

Do we still need to configure a routing in RUT955?

Are there any other settings to consider, e.g. firewall?

Has anyone ever done this with an Openvpn AS server and can help us?

We thank you in advance.

Hi,

For the current configuration the only routing information is needed to be inserted into RUT955 OpenVPN client config is:

• Remote network IP address (Server's LAN IP range)
• Remote network IP netmask (Server's LAN subnet)

To enable client-to-client communication you need to insert "client-to-client" option into your OpenVPN server configuration.

Also to enable client-to-client communication OpenVPN server has to push routes to each client about other clients networks e.g.:

• route 10.200.10.0 255.255.255.0
• route 10.200.11.0 255.255.255.0
• route 10.200.12.0 255.255.255.0
• route 10.200.13.0 255.255.255.0

If there'll be any issues with the setup, we can arrange remote session via Anydesk and I'll help you to resolve your issue.
