      Hi,

      Is it possible to create a pool outside the subnet of the interface?

      I explain :

      I have an interface with IP 10.10.1.1/24. I have 2 L3 switch that I want to be gateway for different VLAN. By exemple, one VLAN on L3 Switch is on 10.10.5.0/24. I want endpoints connected to that VLAN to use this L3 Switch as Gateway (10.10.5.1) and setup this L3 Switch with DHCP-relay to pfsense at the interface 10.10.1.1

      Do I need to summarize my subnet on my interface to be /18 exemple to contain all other subnet VLANs I want to create and be able to create other DHCP pools? If yes, I think its less secure because my goal is to segment my VLANs and isolate them?!?!

      I think creation of VLan interface for each VLAN I need DHCP server isn't a good idea, I dont want traffic to go to pfsense if its not needed. I want local traffic to be managed by L3 switch?!?!

      Any suggestion sould be welcome!

      Thanks!

        I run a layer 3 switch with Pfsense. I use the layer 3 switch for DHCP not Pfsense.

        Microsoft has a very nice DHCP server that will work. I have used both.

          @coxhaus Thanks to answer.

          I think I dont have choice to user another DHCP than pfsense for that case ... I dont understand why developper never worked on that? With all research I've done about that, a lot of people tried to do that with pfsense without success!!! Finally use another like Microsoft one!

          Thanks!
