Hey guys
thanks to all for your answers.
I reached out to Meraki support.
First of all, they will enable FQDN to be configured on the Non-Meraki VPN peers, then
The recommend custom profile is:
- Phase 1
- Encryption AES 256
- Auth SHA-1
- DH group 5
- Lifetime default 28800
- Phase 2
- Encryption AES 256
- Auth SHA-1
- PFS group Off
- Lifetime default 28800
After I had the parameters configured, they asked for my confirmation, and I guess then is when they enable the IKEv2 parameters for the specific VPN.
Also, another recommendation is to create a test VLAN to be the one available for the VPN as the traffic from this subnet will be sent to the Umbrella CDFW
