      Hi.

      Not private VLAN, although that would have been interesting.

      We have networks with different AP hardware.  However, the Ruckus will probably be our test bed.

        If I had a layer 3 switch available (and it sound like you do), I'd use it to handle the VLANs. Put the pfsense inside interface on its own VLAN/subnet and let the layer 3 switch route between the VLANs and pfsens. Use ACLs on the switch to keep the various subnets from talking to each other.

          That is certainly an option to consider and with some appeal - It would help simplify the firewall rules etc.  Currently we are using Layer 2  switches that support POE + VLAN, so this would be an addition of around £1,000.  Cheaper if we could get PFSense to do it :)

          I do like the idea that a small Layer 3 switch feed multiple Layer 2 switches that span to the different AP units.

          Where would the DHCP come from in this instance as I assume PFSense would not be able to fulfill this role in this case?

            You should be able to put helper IP addresses (cisco terminology) on the VLAN interfaces in the layer 3 switch that forward DHCP requests to the pfsense box. I assume pfsense could be configured with a scope for each subnet. I've never tried that with pfsense, though.

              Since you have virtualization available, you might also consider using a virtual router to take the place of the layer 3 switch. I've never used anything other than Cisco routers, so I can't offer specific details, but I'd think it wouldn't be too difficult to create a virtual linux instance, trunk all 300 VLANs to it, set up routing in linux and use iptables for the ACLs.

              I seem to recall that someone has a linux distribution specifically created to be a router.

                  Most L3 switches would support DHCP, you can also set a separate small Linux box to run dhcpd and then "ip helper" each VLAN to that IP.

                    If pfsense DHCP won't do multiple scopes, then you need something that will. It sounds like you need either a layer 3 switch that does DHCP, or a virtual router to do your layer 3 routing and hand out IP addresses.

                    Even if pfsense could be fixed to handle 300 VLANs, you still need something to run DHCP with a scope for each VLAN/subnet.

                      pfSense will do multiple scopes just fine. It just can't be configured to accept helper requests from multiple subnets on one interface.

                        Well that's just silly.
