mbox can function as a DHCP relay to forward host/client DHCP requests to an external DHCP server.  Please refer to this link for more details on mbox DHCP features.

 When configuring dhcp-relay interfaces, following conditions apply:

• • mbox must be reachable to upstream DHCP server

  • can assign dhcp-relay to specific interfaces only

  • when dhcp-relay is configured on the interface, we can not enable dhcp-server (eg. configure mbox to assign IP addresses) on the same interface

NOTE: we can not have both dhcp-server and dhcp-helper running on the same mbox, because both of these services are using the same opening ports (UDP/67/68). mbox can either act as a dhcp-server or dhcp-helper (while dhcp client is supported at all circumstances as this is just a interface specific utility). 

CONFIGURATION STEPS

• • configure a L2TPv3 tunnel

  • configure VLAN interfaces on LAN ethernet port, assign each VLAN to a bridge

  • configure VLAN interfaces on L2TPv3 tunnel, assign each VLAN to the same bridge
