IPSEC PSK Re Authentication Issue



  • Hi

    pfSense connecting to Draytek router.

    We have an issue that the VPN goes down for between 2 - 15 minutes when PSK re authentication happens.
    After this time period the VPN works normally until the next re authentication.
    The pfSense is the initiator and has auto ping host configured.

    Can anyone advise what could be causing this or what we should be investigating ?

    Thanks



  • Hi

    Any anyone got any suggestions how to resolve this ?
    or guidance of what we need to check.

    Thanks



  • Can anyone point me in the right direction to diagnose this issue. ?
    How can I find out what causes the delay in the authentication ?

    Thanks



  • Hi Malik,

    Please share your configuration, both ends please.



  • Thanks for taking the time to reply.

    Attached are the setting for both ends. I've removed the public IP Addresses and anything that is personal to the user.

    I'm happy to change this if it's needed to get the PSK Re-Authentication working quicker.

    Thanks
