    Hi All, I am having some problems with VLAN 2 not getting IP addresses from my Windows 2019 server DHCP.
    It has 2 scopes: default scope (10.0.0.x) and vlan2 (10.0.2.x)

    The default SSID is working fine with the default scope DHCP. but vlan2 SSID_vlan2 is not getting IP address from the DHCP server. I do have routing working since if I assign a static IP, it works fine; Intra-VLAN and the internet.

    I feel like something is dropping the VLAN tags, but I can't think of anywhere.

    My setup is as follows:

    ISP > PFSense > Unifi 24port POE+ Switch >Unif AC PRo

    I have set up the vlan2 definition on unifi. Also ports are set to allow all VLANs.

    Any pointers please and appreciated!!

      YES...got it working. to help those that maybe running into this.
      Step1: Create DHCP Scope on your windows server.
      Step2: Create vlan in PFSense
      Step3: Assign new VLAN interface to you LAN trunk from PFSense
      Step4: Create Rule to allow new vlan to access other networks as desired. (in my case default vlan as my DHCP server is also DNS)
      Step5: PFSense DHCP relay select the new vlan (make sure your LAN and VLANs are all selected)
      Step6: Unifi Controller Create new Network with vlan ONLY with your new vlan.
      Step7: Create new SSID using new vlan
      DONE!
