Hello,
Looks like 217.12.253.226 does not reply:
ike_send_packet: Start, retransmit previous packet SA
Is 217.12.253.226 behind a firewall or stateful NAT, or is the an ACL preventing pkts sourced from 83.234.107.110 to reach 217.12.253.226? Loopback filters on 217.12.253.226 and/or 83.234.107.110 perhaps?
Please double check the above points, then if still not working pls enable IKE debug on 217.12.253.226, repeat the test and post sanitized kmd log here.
HTH
Thx
Alex
