      2.1-RELEASE  (amd64)

      I have 2x lan on the same network (the same vlan)
      DHCP configuration:
      LAN1:  address range: 10.0.1.180 - 10.0.1.200 with Deny unknown clients
      LAN2:  address range 172.16.1.10-172.16.1.20 with Deny unknown clients

      Lan1: 150 static mac addresses + static address
      Lan2: only 3 static mac addresses + static address
      Why komputer with mac address from list LAN1 got adress from LAN2?

      I need to divide my network into known and unknown computers.

      My pfSense box w HA:
      Master: HP DL360G8 1x E5-2670, 64GB ECC RAM, 8x NIC (17x VLan)
      Slave: HP DL360G5, 2x E5410, 64GB ECC RAM, 6x NIC (17x VLan)

        if LAN1 and LAN2 connected to the same switch, and without setting/separating the switch ports into VLANS, it will cause confusion.

            I created 3 VLANS.
            1 10.0.0x
            2 172.16.1.x
            3 192.168.1.x

            Lan1: 150 static mac addresses + static address (and dynamic adress 10.0.0.200-10.0.0.210)
            Lan2: ~50 static mac addresses + static address (and dynamic adress 172.16.1.230-172.16.1.240)
            Lan3: DHCP disabled.

            In LAN2 any komputer from LAN1 are not configured. Why, when i connect any komputer from LAN1 to LAN2 i get adress from dynamic range adress eg 172.16.1.231
            The same situastion is in when i connect computer from LAN2 to Lan1.
            I would like to these networks were totally separated. In my opinion it should not be.

            My pfSense box w HA:
            Master: HP DL360G8 1x E5-2670, 64GB ECC RAM, 8x NIC (17x VLan)
            Slave: HP DL360G5, 2x E5410, 64GB ECC RAM, 6x NIC (17x VLan)
