Getting IPEv2/IPSec/PSK Mikrotik <-> Android 13+ VPNs working (and maybe other key sharing methods, too)

Hello,

Thank you very much for this detailed sharing on configuring IKEv2/IPsec/PSK on Android 13+ devices with Mikrotik. It’s interesting to see how a small change in the ID settings can solve a problem that seems, at first glance, quite complex.

This reminds me of the importance of detail and precise configuration in another area: email testing tools. Just as a VPN requires a specific configuration to work properly, email testing tools need to be meticulously tuned to ensure the effectiveness of email campaigns. A pertinent question would be: To what extent can attention to detail in the configuration of email testing tools influence the success of email marketing campaigns?
