    Not sure if pfSense supports this, but trying to use pfSense as a firewall with NAT etc. Have OSPF routing configured for networks behind it. Now I'm trying to configure DHCP scopes that are not locally connected to pfSense box. All it has is one LAN interface that is connected to the rest of the network. It also has a WAN interface to internet etc. Can you configure scopes that are not local and use DHCP-helper or relay on the network switches/routers? Didn't see any guidance on how to do that and I would hate to spin up another Windows Server that takes care of that.
    Thanks,
    Olaf

      AFAIK pfSense can only serve DHCP to "interface ranges"

      If you find my answer useful - Please give the post a 👍 - "thumbs up"

        @olafb said in DHCP server for remote networks:

        You don't need to spin up a whole windows server, something as simple a vm or docker running isc dhcpd could provide the dhcp scopes for all of your networks.

        But yeah pfsense is not able to provide dhcp ranges for networks that are not directly attached. It can point to some other dhcp server via dhcp relay. But it can not provide the scopes that are not directly attached.

          I raised a similar topic back in 2021 or so. This would be a really nice feature of the pfSense.
          Since all my networks behind a l3 switch, there are also other functionalities that are not working such as pfblocker etc.
