VPN IPsec tunnel keeps disconnecting

  • Hi guys,

    I have 3 sites (A, B and C). Here is the setup:

    • Site A pfsense:
    • Site B pfsense:
    • Site C peplink:

    Site A-B are connected with site-to-site using OpenVPN where Site B is the Server and A the client.

    Site B-C are connected with IPsec. I have created 2 tunnels to reach the and networks from the

    So the problem I have is that the keeps alive always and the disconnects from no use. To bring it back to live I have to send a ping request from over to and then all works. But if I pink from to it doesn't work to bring it back to life.

    Any clues how I can get this working so that this tunnel doesn't disconnect?
