- Are you having issues creating a non-Meraki VPN tunnel with an MX?
- You do not know where the problem is?
- Do you want to understand the traffic flow of the VPN tunnel creation?

In this opportunity, we will go through the VPN settings, the expected behavior and the most common scenarios that you will encounter when you are having issues with a Non-Meraki VPN connection. This video will help you to have a complete understanding of the traffic between the Non-Meraki VPN peer and the MX Security Appliance as well as the event logs in order to understand in a fast and reliable way what is the root cause of your problem.

I encourage you to go through the whole video to examine the different scenarios including the last one with the expected traffic flow in a normal and healthy interaction.
