Hi,
i had configured open vpn on fedora n its working fine. i had created 3 clients certificates all of 3 clients can easily connect to openvpn but when i connect all 3 clients at a same time from diffrent location than problem arises.
openvpn is only able to give ip to only one client 10.8.0.6 and other two clients cant connect to vpn.
giving u the server and client.conf configuration.

Are you trying to just use one client config and key pair? If so,
