OpenVPN not seeing network behind windows server?

Question

openvpn

Good afternoon, colleagues!
Office LAN 1
192.168.8.0/24
Office LAN 2
192.168.9.0/24
Between them, OpenVPN Server, installed on Windows 10 at 192.168.8.0/24
, the connection between the tunnels is established. The problem is that clients do not see computers from the 192.168.8.0/24 network in order to connect to them via rdp.

Answer 1

If I understand correctly, then in 8.0/24 there is a server, and in 9.0/24 there is a client
Add to the config route 192.168.9.0 255.255.255.0so that the gateway is aware of the new network.
Take it away route 10.10.10.0 255.255.255.0.
Meaning: the server must know about all the networks behind the clients.
iroute specifies where to route traffic inside openvpn. In your case, there is no instruction to route 192.168.9.0/24 via openvon in the config.
