Access to OpenVPN client's subnet

[Krukosz]

Hi,

I have 2 LANs in 2 different locations and I linked them with OpenVPN, but it doesn't work completely.

My config:

SERVER: router (10.21.92.1) --- internet
CLIENT: internet --- ISP router (DHCP) 10.20.92.2 --- openVPN router (10.20.92.1)

On one forums I get knowledge, that connecting this specific client will cause, that whole 10.20.92.1/24 subnet will be accessible for all vpn network, but for now I cannot do this.

I can ping 10.20.92.1 from any other direct-connected vpn client, but can't do the same with any client from 10.20.92.1/24 subnet.
Could this config even work in the way I want to?
