Meraki is updating its device-to-cloud connectivity to an architecture that was crafted from the ground up to provide even greater security and simplicity for connectivity.
So, you have to follow this:
- Preshared secret must be greater than 14 characters
- Authentication cannot be MD5
- Diffie-Hellman Group must be 14
- Phase 2 encryption cannot be NULL
- PFS can be configured to be either off or 14
I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
Please, if this post was useful, leave your kudos and mark it as solved.
