    Hala Ranjith and welcome to the UTM Community!

    I don't recognize that log format - is that from the Palo Alto device?

    I'm not familiar with the PA device, so you might also need to go to the equivalent community on their site.

    IPsec in the UTM does not accept Aggressive Mode, only Main Mode.  Once you've resolved that, if the connection still doesn't succeed, show us the IPsec log from the UTM:

    1. Confirm that Debug is not enabled.
    2. Disable the IPsec Connection.
    3. Start the IPsec Live Log and wait for it to begin to populate.
    4. Enable the IPsec Connection.
    5. Copy here about 60 lines from enabling through the error.

    Cheers - Bob

    Dear Dirkkotte/ Bob,

    thanks for your inputs.

    however now tunnel is coming up but after some times (may 1 hour , 2 , 3 hr) tunnel going down automatically. see the logs below:

     I see that remote end sending delete message:

    2019-10-24 23:07:53 17[IKE] <DB_05P_TO_DU-1|19> received DELETE for IKE_SA DB_05P_TO_DU-1[19]

    Any thoughts on the above why PA sending the delete message to disconnect the tunnel (we don't have any access to remote Peer PA, not easy to get the logs as well )

    Appreciated your inputs.

    Thanks in advance,

    Ranji

    A new/next problem?

    Do you enable/disable DPD at booth sides?

    Matches the IPSec Phase1 / Phase 2 timers at booth sides exactly?

    Dear Dirk/Bob,

    Same vpn. Tunnel establishing now but disconnects frequently.

    Yes already configured DPD on both ends :

    Intervel- 30sec

    Retry-120 sec

    Many Thanks,

    Ranji

    Try to disable DPD at booth sides.

    Some IPSec implementations only send DPD packet if there is no other traffic, other implementations only check DPD for alive-status (but ignores regular traffic).

     

    PS: Sophos XG knows IKEv2 (and i think PA too). Would use IKEv2, because some features directly integrated (DPD for example) and connection should be more stable.
