pfSense as DHCP server without interface for each subnet



  • I have cisco L3 switch with some vlans
    10.10.1.X/24
    10.10.2.X/24
    10.10.3.X/24
    my pfsense has only 1 100Mb interface, so i want to route traffic between subnets inside cisco, pfsense will route only trafic to WAN.
    pfsense config:
    WAN - int.1 - DHCP
    LAN - int.2 (10.10.0.1)
    Is it possible to create 3 DHCP subnets inside pfsense and set ip-helper to 10.10.0.1 on cisco?

    100Mb interface,

    Hi,

    Most L3 Cisco switches include a built-in DHCP server that you can configure for any of the configured VLANs...

    pfSense can only assign a DHCP server to an interface, just like any other tool..

    which I don't recommend because of port 100 (fast ethernet), but it can be a solution ...
    create VLANs in pfSense and assign a DHCP server
