For instance, Palo Alto firewalls you can chose the timer as a period of days etc. In Phase 2, the VPN peer or client and the FortiGate exchange keys again to establish a secure communication channel. Even if the FortiGate has the correct number of seconds in the timer that matches said day period of the Palo the connection will fail. Example 4-1 provides the ISAKMP policies configured for Router_A in Figure 4-1. The most common problem with IPsec VPN tunnels is a mismatch between the proposals offered between each party. 103:500->187.

Customer Service. It is possible to see the proposals are not matching, causing the phase2 negotiation to fail. They have to match the same encryption and authetication settings on both sides. To elaborate a little on what @bojanzajc6669 has said . no SA proposal chosen The errors I see on the FortiGate side says: Status: negotiate_error, Message: IPSec phase 2 error, Reason: peer SA proposal not match local policy I have gone over the configs until my eyes are ready to bleed, and they are identical. Note that, in this configuration, there are no ISAKMP In my understanding, QM selectors of 0. In this scenario, you could have AES-256 SHA-256 but it not be configured on the other side. The most common problem with IPsec VPN tunnels is a mismatch between the proposals offered between each The SA proposals do not match (SA proposal mismatch). In this example, I left ONLY AES-128 SHA256 while the remote firewall had the AES-128 SHA256 removed causing a mismatch. The FortiGate uses the HMAC based on the authentication proposal that is chosen in phase 1 or phase 2 of the IPsec configuration. no SA proposal chosen ike 0:TRX:322: PSK auth failed: probable pre-shared key mismatch ike Negotiate SA Error: The SA proposals do not match (SA proposal mismatch). 0 255. no SA proposal chosen This will provide you with clues as to any PSK or other proposal issues. 255.

FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs It generally suggests that there is a mismatch in the hash algorithm used for this signature generation. Here are partial IKE negotiation logs between FortiGate and Zscaler that show the remote side is rejecting authentication messages sent by the FortiGate side: All messages in phase 2 are secured using the ISAKMP SA established in phase 1. FortiGate does not derive this hash algorithm from the phase1 proposals and by default uses SHA-1 to avoid interoperability This article discusses the IKEv2 messages and their meaning. It was noted in this case that the FortiGate which was upgraded added a new phase2 object, making the phase2 go down. no SA proposal chosen I tried to debug non-working VPN tunnel and suspect there is PSK mismatch. 1, 500 FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic. 31. Fortigate doc says: "It is possible to identify a PSK. On the Fortigate you need to configure a separate SA for the 2nd local subnet. Administrators should know that FortiGate will not successfully negotiate the IKE traffic to avoid later troubleshooting issues as FortiGate needs to allow the users' traffic later. this is not the case with FortiOS. The Azure VPN is setup as route based, however it's only advertising the VNet subnet, instead of any-to-any. I tried to debug non-working VPN tunnel and suspect there is PSK mismatch. - Ensure that inbound and outbound traffic are allowed for all necessary network services, especially if services such as It still seems the proposal doesn't match.
