Proximus

Managed DHCP

Set-top box must have DHCP lease of Proximus BBOX. So if another DHCP is authoritative for the leases in the private LAN, a block list or a deny needs to be introduced for the MAC address for the STB on the other DHCP server.

Note, you cannot disable the DHCP server on the BBOX for the STB range, only for regular LAN clients.
