These businesses often have to access resources housed on a primary network, which could include servers that facilitate email or store data. Site-to-site VPNs are useful for companies that prioritize private, protected traffic and are particularly helpful for organizations with more than one office spread out over large geographical locations. This could be a corporate network where multiple offices work in conjunction with each other or a branch office network with a central office and multiple branch locations. This will ensure that the phase2 is successfully negotiated.A site-to-site virtual private network (VPN) refers to a connection set up between multiple networks.
Either users can unset the localid option or manually set it to ‘auto’. In the previous configuration, localid-type is set as keyed but no string value is assigned to the ‘set localid ’ command.
Make sure that the P1 interface had localid-type set to ‘auto’ instead of ‘key-id’. This error message can appear when either using IKEv1 or IKEv2. Ike 1: To_Initiator:107665: detected retransmitĪfter the responder fails to calculate authentication information, the initiator will try to send authentication information periodically. Ike 1: To_Initiator:107664: error calculating auth informationĪfter the responder fails to calculate authentication information, the initiator or peer will try to send authentication information periodically and phase2 will remain down. Ike 1: To_Initiator:107664: processed INITIAL-CONTACT Ike 1: To_Initiator: schedule auto-negotiate In IKE debug logs, it can be seen that phase1 negotiation is successful, in phase 2, the negotiation stops when the responder is unable to process the authentication message sent by the initiator.īelow KB article can be used to generate IKE debug logs: In this scenario, the IPsec tunnel is configured between FortiGate and FortiGate/non-Fortinet peer, with appropriate phase1 and phase2 configuration on respective nodes, the phase 2 remains down. This article describes an IPSec scenario with error ‘error calculating auth information’ in IKE debug logs
