IPsec tunnels between two devices have many configuration options and settings that need to be aligned for the tunnels to come up correctly. In fact we see hundreds of cases per month for configuration assistance requests for VPN tunnels. In an effort to make things easier for our customers I wanted to introduce you to a tool that has been developed by myself and a few other Cisco TAC security engineers.
The tool checks the configuration of two devices (IOS or ASA), examines for the presence of a crypto map based tunnel between them. If discovered it will do an analysis of the most common configuration mistakes and best practices. This tool's goal is to help you identify any configuration reasons why your tunnel is not establishing or traffic is correctly passing over it.
Currently there it only support static crypto map Lan-to-Lan tunnels between IOS, IOS-XE and ASA devices.

Mac(Catalina)のおよそ100台の端末に対してAnyConnect4.9.05042をWeb展開したところ、一部端末でエラー「Failed to load preferences」表示で接続できない事象が発生しました。Profileのxmlファイルに対する権限がなくなっていたことが原因で、権限付与したところ接続できるようになったのですが、今後のトラブル回避のために、原因と対策に関する情報がありましたらご教示ください。
