Jun 18, 2019 · IKE traffic leaving your on-premises network is sourced from your configured customer gateway IP address on UDP port 500. To test this setting, disable NAT traversal on your customer gateway device. UDP packets on port 500 (and port 4500, if you're using NAT traversal) are allowed to pass between your network and AWS VPN endpoints.

Send IKEv2 Cookie Notify - Sends cookies to IKEv2 peers as an authentication tool. Send IKEv2 Invalid SPI Notify – Sends an invalid Security Parameter Index (SPI) notification to IKEv2 peers when an active IKE security association (SA) exists. The IKE SA specifies values for the IKE exchange: the authentication method used, the encryption and hash algorithms, the Diffie-Hellman group used, the lifetime of the IKE SA in seconds or kilobytes, and the shared secret key values for the encryption algorithms. The IKE SA in each peer is bi-directional. Aggressive Mode From now on, if additional CHILD_SAs are needed, a message called CREATE_CHILD_SA can be used to establish additional CHILD_SAs. It can also be used to rekey IKE_SA where Notification payload is sent of type REKEY_SA followed by CREATE_CHILD_SA with new key information so new SA is established and old one is subsequently deleted.
ISAKMP protocol is a framework for exchanging encryption keys and security association payloads. IKE uses UDP, Port Number 500. Internet Key Exchange Version 1 (IKEv1) The operation IKEv1 can be broken down into two phases. 1) Phase 1 (IKE SA Negotiation) and 2) Phase 2 (IPSec SA Negotiation). IKEv1 Phase 1 SA negotiation is for protecting IKE.
