Open VPN netmask 255.25.255.252



  • I'm getting the tunnel, but with this mask 255.255.255.252. I need 24-bit chews.
    What is wrong?
    Need any virtual network route to the openvpn?



  • On OpenVPN Server you set the tunnel network. for example

    10.10.10.0/24

    10.10.10.0/30 is the OpenVPN Server itself
    10.10.10.4/30 is the first OpenVPN client which connects
    10.10.10.8/30 is the second OpenVPN client which connects
    ….
    10.10.10.252/30 is the 63rd OpenVPN client which connects.

    In short:
    Every client connection on OpenVPN needs a subnet of /30

    First IP: Network IP
    Second IP: OpenVPN Server IP
    Third IP: OpenVPN Client IP
    Foruth IP: Broadcast IP

    This is how every client connection/subnet looks like.
