I'm having an issue with a VPN tuunel between my Firewall (ASA 5516-X) and a third party firewall so I can't check the config in the second firewall. So I decide to debug my firewall and I realized that phase one wasn't complete and the only message that I get in the debug is:

IKEv2-PLAT-2: Received PFKEY DPD for SPI 0xF671D605, error FALSE

enter image description here

Searching for something else in the log I found that every time I apply the tunnel configuration the lines in the picture are shown:

Does anyone know what could be the problem?

  • if you turn on ikev2 debugging, you should get a lot more messages. That message is about dead peer detection.

  • Is the only message I get during debug AsaTriara# debug crypto ikev2 protocol 200 AsaTriara# debug crypto ikev2 platform 200 Jun 27 '19 at 18:59
  • It doesn't look like either you or the peer is starting IKE negotiations. I don't see any IKEv2 messages. Maybe they're not using ikev2?
