      Hello,

      i want to use a GRE-Tunnel to some remote wireless controllers and also provide DHCP via this tunnel.
      But i can't configure this.
      Now, i think the only way is to add some physical interfaces, all in same "landing" subnet, so get this done.
      Any hints here?

        There isn't a way for pfSense to provide DHCP to a subnet that isn't connected at layer 2 currently. So you could relay DHCP to some other device, maybe, or (and this is uglier), setup a GIF tunnel (not GRE), bridge the GIF to a local interface that has link somewhere, and run DHCP there. May not work, but has the best chance to succeed currently.

          Because i'm using Captive Portal in the mentioned network i would prefer to service DHCP from pfSense itself.
          Well, GRE is able to route all traffic, even broadcast-traffic. But for some unknown reason the GRE-interface is not shown as possible DHCP-Interface.
          Could the be done by a feature-request?
