      Hello,

      on my pfSense I have 4 connected NIC´s.
      1: WAN
      2: LAN 1 (tagged VLAN 400,10)
      3: LAN 2 (tagged VLAN 200,300,400,10)
      4: LAN 3 (tagged VLAN 100,200,300,10)

      VLAN 400 for example is the network for teachers.
      DHCP Server vor VLAN 400 is active. (network 10.1.1.0/24)

      But I need to set for each NIC an IP address.
      So I need on LAN1 an IP address and on LAN2 an IP address in the VLAN400.

      Is it possible that the pfSense has for VLAN400 just 1 IP address? And the other as well.

      Thank you!

        How you've split the vlan numbers across the LAN interfaces LAN 1 vlan 400 is a different broadcast domain than LAN 2 vlan 400 and would need a different IP address, same with the other VLANs.

        Maybe you need to look at LAGing the 3 LAN ports on pfSense and the switch they connect to.

          You may want to read about VLANs. On pfSense, each VLAN is a separate interface, which can be configured for IP address, subnet mask, etc., just like any other. If you have them all on one physical interface, then you'd need a managed switch to separate them. This is standard stuff for VLANs.

          I haven't lost my mind. It's around here...somewhere...
