Hi !
I have configured an OpenVPN server on a Windows 10 Pro computer.
From my OpenVPN client laptop (also Windows 10 Pro), I can establish the connection with the server.
But, I can not put in place the right configuration to manage to communicate between my OpenVPN client and other computers on the LAN network f the OpenVPN server.
A small diagram will be more effective than a long speech:
+-------+ +------+
|OpenVPN| LAN IP : 172.20.10.6 | |
|client | VPN IP : 10.8.0.2 +-----+ PC 2 | LAN IP : 192.168.1.11
+---+---+ | | |
| | +------+
| |
| | +------+
| | | |
+---+---+ -----+ PC 1 | LAN IP : 192.168.1.12
| | LAN IP : 172.20.10.1 | | |
|Router | | +------+
| | WAN IP : 80.215.65.186 |
+---+---+ | +-------+
| +-----+OpenVPN| LAN IP : 192.168.1.73
| | |Server | VPN IP : 10.8.0.1
| XXXX X | +-------+
| XX XXXX XXXX |
| X X +---+---+
| XXXXX X | | LAN IP : 192.168.1.71
+--------+ XXX+-----+Router |
X INTERNET X | | WAN IP : 109.190.130.188
X XX +-------+
XXXX X
X XXXXXXX
XX XXX
XXXXX
So, 10.8.0.1 can ping 10.8.0.2, and 10.8.0.2 can ping 10.8.0.1.
But, from 10.8.0.2, I can't ping 192.168.1.12.
Here is the configuration file of my OpenVPN server :
port 1194
proto udp
dev tun
ca "C:\\Program Files\\OpenVPN\\config\\ca.crt"
cert "C:\\Program Files\\OpenVPN\\config\\server.crt"
key "C:\\Program Files\\OpenVPN\\config\\server.key"

tls-auth "C:\\Program Files\\OpenVPN\\config\\ta.key" 0

Here is the configuration file of my OpenVPN client :

persist-tun
ca "C:\\Program Files\\OpenVPN\\config\\ca.crt"

tls-auth "C:\\Program Files\\OpenVPN\\config\\ta.key" 1

cipher AES-256-CBC

Maybe it is a problem of route configuration, but I don't know what to add or modify.
Here is the route table of the OpenVPN client laptop :

Is someone have an idea ?
I searched for tutorials, but not yet find something interesting regarding this case.
Thanks.
