Anyone have any ideas The Log message Payload processing failed indicates there is a mismatch of proposals during phase 1 or phase 2 negotiation between a site-to-site VPN. Flags: IKE SA is created . Any idea what may be going on? Thanks. RFC 7296 IKEv2bis October 2014 IKE performs mutual authentication between two parties and establishes an IKE Security Association (SA) that includes shared secret information that can be used to efficiently establish SAs for Encapsulating Security Payload (ESP) [] or Authentication Header (AH) [] and a set of cryptographic algorithms to be used by the SAs to protect the Hi guys. DH Compared with IKEv1, IKEv2 simplifies the negotiation process and is much more efficient. Hi Forum, Unable to set up a tunnel between identical ASA 5525-x over the internet even after much troubleshooting. x[500] cookie: This document describes how to extend the Internet Key Exchange Protocol Version 2 (IKEv2) to allow multiple key exchanges to take place while computing a shared secret during a Security Association (SA) setup. This document describes how to extend the Internet Key Exchange Protocol Version 2 (IKEv2) to allow multiple key exchanges to take place while computing a shared secret during a Security Association (SA) setup. Thanks The KE (Key Exchange) payload contains the peer's public DH (Diffie-Hellman) factor and the DH group. y. y[500] cookie:84222f276c2fa2e9:0000000000000000 due to timeout. The CHILD_PFS_INFO results in immediate negotiation failure that can be repaired before taking the IPsec connection First pair of messages is the IKE_SA_INIT exchange.

So, not seeing the VPN re-negotiate, I don't see right before that which might indicate why the VPN dropped. An EESP SA can be negotiate using IKEv2 in IKE_AUTH or CREATE_CHILD_SA new SA, exchange.

I did run all the debug commands, and looks like the "timeout" message is more a symptom of a "stuck in Phase 1" problem. I have a site to site connection from the ASA to an Azure subscription. These messages negotiate the cryptographic algorithms, exchange nonces, and perform a Diffie-Hellman (DH) exchange. < HUAWEI > display ikev2 statistics eap Ikev2 eap and modecfg statistics: ----- Eap user auth success :0 Eap auth timeout :0 Eap auth fail :0 Eap user get authorized IP address :0 Eap user go online number :0 Eap user go offline number :0 Eap user cut message :0 Send ip address allocation request :0 Send ip Description This document is a reference to interpreting IKEv2 log messages. due to the nature of the IPsec the initiator will not log the real reason why negotiation is failing.

The Hello Folks, I am trying to build a site to site vpn between a Palo Alto firewall running 8. When IKEv2 negotiation fails, the log messages are in general the only helpful place to debug, since the later states of the ISAKMP exchange are encrypted making a packet capture unhelpful. %ASA-4-750003: Local:x.
