Question 520
A production deployment must address this scenario: A peer sits behind upstream NAT and the IKE identity differs from its interface address. Which change is the best fit?
Explanation
Correct Answer
This avoids the relevant failure: The receiving gateway authenticates an unexpected peer identity or sends return traffic to the untranslated address. Verify the result by checking: IKE and IPsec negotiations survive through the NAT device with expected endpoint identities.
