I have setup an openvpn network, I have in my client windows two interfaces, one public with IP 188.8.131.52 and the openvpn interface, with ip 192.168.244.10
I am able to ping from windows to the server's interface IP 184.108.40.206 and wireshark says that the source IP address is correctly 192.168.244.10, the destination 220.127.116.11 and this works. But when I try to ping from the openvpn server to 18.104.22.168 (client public interface), wireshark in the client side says that is receiving the request (source IP 22.214.171.124 and destination 126.96.36.199), but no reply is sent.
So as far as I can understand there is no openvpn problem, openvpn normally is sending the icmp packet from server to the openvpn client IP but windows is not sending back a reply. So, why windows is not forwarding from interface 188.8.131.52 to the windows openvpn client interface 192.168.244.10, in order to send reply back to the openvpn server?? I have already enabled this in the registry, firewall also is disabled.
