DHCP relay on MX

[Pedro098]

Hi,

We want to use a DHCP server in our datacenter, reachable via an external router connected to the WAN interface of the MX. I noticed the following restriction when configuring the dhcp relay server on a Vlan configured on the MX "IP address of DHCP server to relay to. The IP address must be in a subnet connected to this Meraki network or to a Meraki network reachable through site-to-site VPN. Relaying through a non-Meraki VPN peer is not supported".  Does anyone have a workaround?

Thanks Peter

Put an MX into your data centre and use AutoVPN?

Usually data centers via routers are connected on the LAN site of the MX so you can have a simple static route that points to the router to reach the datacenter.  In that case you can easily use the DHCP relay.  Or go the AutoVPN route.

Traffic that goes out the WAN port usually is NAT'ed so that would explain why you can't be relaying dhcp requests that way.
