    <p>Is there a change from previous version that could affect auth
      with xauth? <br>

    <p>or is just that the shrew client is to old and i should stop

      <br>
      <br>
      In version 3.29 i cannot connect shrew vpn client and i don't get
      why, probably something with new ike negotiation.
      <br>
      <br>
      other clients (android, cisco client) are working ok.
      <br>
      <br>
      the configuration (client and server) was working in previous

      The output of the connection is:

      <br>
      <br>
      I guess that is something related to the new changes for IKE
      negotiation.

      Thanks for the help.
