OPENVPN is broke



  • Hi Guys,
    sinds today the openvpn is broke and can't connect.
    the connection shows UNDEF.
    the firewall is hardware and been rebooted twice.
    on the firewall logs there are no log drop or block packets.
    can someone please help.
    thank you

    So is this a client connection from pfsense to some vpn service?  inbound road warrior connections to pfsense as the openpvn host?  A site to site connection?

    What exactly shows UNDEF?


  • Rebel Alliance Developer Netgate

    UNDEF usually shows up when the server is not receiving enough (or valid) data from the client during the connection negotiation. For example when it expects a username but the client has not yet sent the username.

    It's likely not a problem on your server at all, but a WAN quality / service issue or a problem on the client end. For example, you'll see that when a client's WAN is so degraded that they cannot send or receive all of the required data during the connection process.



  • John,
    this is a openvpn client. when the client tried to connect the tunnel is not up and when i look on the VPN Server status on the dashboard its shows

    Jimp.
    thank you for your answer.
    i've tried from two different machines with two different kind of connection but the same issue exist.

    Firewall rules are set as other pfsense box we have .

    on the openvpn NIC is allowing everything to everywhere

    It's highly unlikely to be a firewall rule problem. If it's getting that far, it's passing through. Check the OpenVPN logs on the client and server for more clues.
