There is an issue that I cannot find answer for. I have typical setup OpenVPN - 1 server with 10.8.0.0/24 subnet and a 1 client with 10.8.0.5 address. Whether the connection from the server to the client is established or not and I am trying to ping anything that is not in VPN subnet I receive duplicates, e.g.:
root@openvpn:~# ping google.com

My question here is - is it normal or there is some configuration to be corrected on client or server side?
