Question 610
A third-party VPN connection uses certificate-based IKE authentication. The peer presents its certificate, but the R82 gateway rejects the issuer because its trust chain was not configured. Algorithms and reachability are confirmed. The controls that address the separate requirement to connect every gateway in a small trusted group directly to peers are already working as designed, and the change ticket must not disturb them. Which R82 action addresses the remaining symptom?
Explanation
Correct Answer
Certificate authentication relies on valid identities and trust. This directly addresses the documented incident evidence.
Incorrect Answers
A Mesh model supports direct relationships among participating members, but the current evidence calls for a different R82 operation.
Both sides need consistent configured IKE authentication secrets, yet that applies to authenticate a third-party IPsec peer with a shared secret rather than the observed issue.
IKE agreement and authentication are prerequisites for tunnel setup; this does not resolve the observed condition.
