Hi @Marcointegrated ,

You can refer to the articles to ensure that no steps were missed during the configuration process.

If the issue persists, please provide the following details:

• Your scenario and network topology, so we can better understand the relationship between your macOS, the VPN100, and the server.
• Information on whether the server is blocking traffic from the macOS.
• Logs from the server when macOS couldn't ping server.

You also can provide remote session details so we can directly check your VPN and macOS setup.
