Create an ACL in Policies > Local Policy > Access Control ListsPermit port 500I also have the Default Action as Accept in my POC.Copy the ACL name (CTRL C) youll need it for the next step. The vulnerability is due to incorrect handling of crafted IKEv2 SA-Init packets. Responder sends the response for IKE_AUTH. Router1 verifies and processes the response: (1) The initiator DH secret key is computed, and (2) the initiator skeyid is also generated.

For more information, refer toIKEv2 Packet Exchange and Protocol Level Debugging. Any luck getting this to work? If this CREATE_CHILD_SA exchange is rekeying an existing SA other than the IKE_SA, the leading N payload of type REKEY_SA must identify the SA being rekeyed. Bug Search Tool - Cisco Router 2 builds the response to IKE_AUTH packet that it received from Router 1. Cisco Bug: CSCvp93211 - Garbage value in IKEv2 error debug I believe it is specific to ISR4K's and being fixed in the November code release. My template for 'VPN Interface IPsec' looks like this: Then, this template is added under the Service VPN : I thought it was all working fine, however I now have a new problem.IKEv2 is working for Phase 1, but IPSEC is failing.For some reason the ISR4K is creating 16 SA's whilst Zscaler only support a maximum of 8 SA's, therefore the tunnel is currently unusable. I opened an SR with TAC for the exact same reason. Use the VPN Interface IPsec feature template to configure IPsec tunnels on Cisco IOS XE service VPNs that are being used for Internet Key Exchange (IKE) sessions. - edited Responder initiates SA creation for that peer. INFO_R Event: EV_CHK_INFO_TYPE IKEv2-PROTO-5: (99): SM Trace-> SA: I . IPSEC interface not available from VPN0 - Cisco Components Used The information in this document is based on these software and hardware versions: Internet Key Exchange Version 2 (IKEv2) Router 1 receives the IKE_SA_INIT response packet from Router 2. For a branch office VPN that uses IKEv1, the Phase 1 exchange can use Main Mode or Aggressive Mode. Windows or MAC (native or AC) client can only use Certificates or EAP. 08-08-2018 It seems like it's not passing domain information. In my case even after adding the ACL entry there was another step which was needed to fix this tunnel. Description (partial) Symptom: Garbage value (non-comprehensible) seen in the ikev2 error line "Address type 4132115430 not supported" Conditions: When ikev2 error debugging is turned on. My assumption is that although the IPSEC is created on the service side, by sourcing the tunnel from the interface with a public IP address in VPN0, the cEdge would VRF jump to VPN0. You can also check the output of theshow crypto sessioncommand on both routers; this output shows the tunnel session status as UP-ACTIVE. All of the devices used in this document started with a cleared (default) configuration. The sample configuration connects a Cisco ASA device to an Azure route-based VPN gateway.
