Thanks Tyler, We have a MPLS network. DHCP server is located in 1 of our DC's which is connected to the MPLS network via resilient 100Mb circuits. At one of our 450 remote sites (all connected via MPLS with centalised breakout) I have deployed an MX65. MPLS provided router peers with the PE via a /32 loopback interface, they then advertise a /24 via BGP for us to use on the LAN. When I physically connect the MX65 via internet port 1 to a LAN port on the Cisco router it indeed picks up an IP address from our DHCP server. The issue I have is, that when I configure one of the Meraki LAN ports to be in the same vlan as the routable /24 the devices do not pick up a DHCP reply. Packet capture can see the request hitting the DHCP server and the response coming back, but it hits the MX and then goes nowhere. I'm aware I can use the MX to manage DHCP, however it's not the way we want to go (for now at least). As an example I have the MX WAN IP as .209 with the LAN IP as .210 with the default gateway on the Cisco router as .220. | have spoken to the support team, and they advise that there needs to be a different subnet between the MX and the Cisco router. I was just curious as to why this is the case, if indeed it is true. Many Thanks
