it looks like the DHCP Relay function to a server which is reachable through a Non-Meraki VPN tunnel can‘t be configured... maybe somebody know why this limitation exist? from technical perspective I don‘t know a reason why this isn‘t supported?!
ok... but the local DHCP-Server on the MX is NO option in the project I‘m currently working on! Unfortunatly another reason more (in the meantime they‘re many...) why I’ve to think twice if the MX is really a security component to compete with other vendors on the market! 🤨
