Sorry. Everything went well. After updating the firmware I have access to IKE v2 parameters.   I had to configure my Azure VPN with powershell :     # first get your current connexion on Azure $connection = Get-AzVirtualNetworkGatewayConnection -Name "Office" -ResourceGroupName "Internal" # then create an IPSec policy whith the lifetime and DH Group you configured on Meraki $ipsecpolicy = New-AzIpsecPolicy -IpsecEncryption AES256 -IpsecIntegrity SHA1 ` -IkeEncryption AES256 -IkeIntegrity SHA1 -DhGroup DHGroup2 ` -PfsGroup None -SALifeTimeSeconds 3600 # Apply policy to your connection Set-AzVirtualNetworkGatewayConnection -VirtualNetworkGatewayConnection $connection -IpsecPolicies $ipsecpolicy -UsePolicyBasedTrafficSelectors $True     It is now working smoothly for a month and it solved a lot of our problems. The only downside is that you have to use a VpnGw1 subscription on Azure VPN which cost more than base subscription but this is way less than a virtual MX.   If you have any other question let me know. Have a nice day PS There is a nice conversation about this : https://community.meraki.com/t5/Security-SD-WAN/IKEv2-support-on-MX-devices/m-p/49088#M12406 ... View more

You still need to ask Meraki to enable IKEv2. I think that you can then change the configuration using the GUI (not tested) ... View more

For reference here is the procedure to change the lifetime on Azure as recommended by Meraki support.   Connect to azure Powershell and execute the following commands : Get existing connexion : $vpnconnection = Get-AzVirtualNetworkGatewayConnection -Name CONNEXION_NAME-ResourceGroupName RESSOURCE_GROUPE Create IKEv2 Policy (Default for Meraki is AES256 Encryption for both phase and SHA1 Integrity. $ipsecpolicy = New-AzIpsecPolicy -IpsecEncryption AES256 -IpsecIntegrity SHA1 ` -IkeEncryption AES256 -IkeIntegrity SHA1 -DhGroup DHGroup2 ` -PfsGroup None -SALifeTimeSeconds 3600 Set policy for connexion   Set-AzVirtualNetworkGatewayConnection -VirtualNetworkGatewayConnection $connection6 -IpsecPolicies $ipsecpolicy6 -UsePolicyBasedTrafficSelectors $True Note that once IKEv2 is activated in Meraki you can change the algorithms supported.   ...

I just contacted the Meraki support. I was asked to upgrade my firmware to beta and call them back to enable IKEv2. Update is schedule for this evening. I will tell you how it worked. ... View more
