Filtering DHCP request

  • Hello everybody,

    I have a WAN interface ( and 2 x LAN ( interfaces bridged with the WAN.

    All computers in the LAN 1 and 2 do a DHCP request and I want to allow a range of IPs in the LAN 1 ( and in the LAN 2 ( by example, it's possible or not ? (Sorry for my english)

    Thanks for your answer,


  • Possible to determine which DHCP lease they get via the firewall when it's just a transparent bridge? No. If your upstream DHCP server has reservations for those hosts so they're assigned predetermined IPs, you can configure your firewall rules to allow/deny as needed to accomplish that scenario in general.

  • Thanks :) I have choose the static IP solution.
