  1. VPN Error 788


    Hi there, recently I got this error when connecting to "L2TP/IPSec with certificate" VPN. I'm not sure what cause this.

    I have already follow some of this steps with no luck :

    • Adding AssumeUDPEncapsulationContextOnSendRule
    • Restarting both IKE and IPSec services
    • Allowing both CHAP and MS-CHAP v2
    • Reset network connection
    • Connect to different provider
    • Re-adding VPN settings

    There also little bit information can be found in the event viewer :


    CoId={AEE0E2A8-34DF-41BB-B5F0-0458EFD41751}: The user xxx\xxx has started dialing a VPN connection using a per-user connection profile named yes. The connection settings are:
    Dial-in User = *\
    VpnStrategy = L2TP
    DataEncryption = Requested
    PrerequisiteEntry =
    AutoLogon = No
    UseRasCredentials = Yes
    Authentication Type = PAP
    Ipv4DefaultGateway = Yes
    Ipv4AddressAssignment = By Server
    Ipv4DNSServerAssignment = By Server
    Ipv6DefaultGateway = Yes
    Ipv6AddressAssignment = By Server
    Ipv6DNSServerAssignment = By Server
    IpDnsFlags =
    IpNBTEnabled = Yes
    UseFlags = Private Connection
    ConnectOnWinlogon = No
    IPsec authentication for L2TP = Machine certificate.


    CoId={AEE0E2A8-34DF-41BB-B5F0-0458EFD41751}: The user xxx\xxx is trying to establish a link to the Remote Access Server for the connection named yes using the following device:
    Server address/Phone Number = xxx.xxx.xxx.xxx
    Device = WAN Miniport (L2TP)
    Port = VPN3-1
    MediaType = VPN.


    CoId={AEE0E2A8-34DF-41BB-B5F0-0458EFD41751}: The user xxx\xxx dialed a connection named yes which has failed. The error code returned on failure is 788.

    Thanks.

    AirVPN

    In contrast to all the big names such as IPVanish, TorGuard, Hide My Ass!, PIA etc, AirVPN has been the most useful in terms of performance, cost, privacy and service.

    • No torrent (or other format) throttling
    • No region/server locking
    • Full server stats live, with reports and repair ETAs
    • Packages include complete tunneling and multiple protocols
    • Can be setup for virtually any platform(including a easy to use Windows package)[also user guides exist for bespoke arrangements, such as pfSense, which I run]
    • Their website/user portal is very thorough and flexible. You can build custom VPN configuration files
    • Cost is extremely good for what you get
    • Service is often quick and prompt
    • Forums are active
    • They tick all the privacy qualifications, no record keeping
