Please add “Managing IP” for DHCP connection type. I know, that you have one for PPPoE, but for DHCH this feature is also necessary.
Can elaborate more on your requirement and the used case?
PPPoE is a network protocol for encapsulating PPP frames inside Ethernet frames. Hence, Management IP is useful here to manage the modem which running in Bridge mode. However, DHCP is running as Ethernet frame. Any device within the same subnet can be accessed by LAN users.
