    Hi  

    Would you please change the IPSec encryption algorithm to AES 256 GCM (128 bit)? The rest of the configuration looks fine to me. 

    Regards

    Thanks Jaydeep,

     

    Tried that but no luck

    Hi  

    I should've asked you about this at first. Do you have configuration details on the Cisco device? The important log line is

    Possible authentication failure: no acceptable response to our first encrypted message


    Would you be able to verify that configuration and PSK matches on both sides? Further, Would you ask your colleagues managing the Cisco device to stop the current IPsec connection and start it again after a timeout?

    Regards

    Jaydeep

    Try Group 5, on no success SHA1

    In my experience, some Cisco-firmwares do no support more in IKEv1

    Hi Peter and welcome to the UTM Community!

    Is your UTM behind a NAT?

    Hi Bob,

    Thanks for the welcome

    We have a Netgear DM200 in bridge mode connected to VDSL and then plugged into eth1

     

    Hope this helps

    Let's take a look at the UTM's IPsec log, Peter.

    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. Show us about 60 lines from enabling through any error.

    Cheers - Bob
