I am currently facing an issue while attempting to establish IPsec tunnels between AWS and a Cisco ASA firewall. The AWS tunnel logs indicate that the Identity Resolution checks are failing, preventing the successful establishment of the tunnels.
I believe this issue might be related to the configuration of the IDr (Identity Responder) on the Cisco ASA. However, I am unsure about the correct steps to configure the IDr and resolve this problem.
I kindly request your expertise and guidance on the following points:
How should the IDr be configured on a Cisco ASA to establish IPsec tunnels with AWS? Are there any specific considerations or best practices to be aware of when configuring the IDr for AWS IPsec tunnels?
