      I have WAN and LAN configured and working fine. I would like to use one of the other free interfaces to set up a separate network. However, despite the port showing connected if I plug something into them, they are not available for assignment and configuration. Why? Device is SG-2100

        Those are switch ports. which I believe are just in the LAN network out of the box.. For you to put them on their own interface you would have to configure that.

        hope this gets you started

          Yes, exactly. Those are ports not interfaces.

          To use one of the LAN ports as a separate interface you need to add a VLAN and then configure the switch to use it on only one port as shown in that guide.

            Thanks, guys. Configured as instructed but I am unable to ping the IP assigned to the interface 192.168.2.1
            I created only two rules: first to block access to the network assigned to the LAN interface (192.168.1.1/24) and second to allow all after that. I must be missing something?

              Lets see your rules.. Rules default to tcp only, so your rule could be tcp any any, which wouldn't allow for ping..

                Where are you trying to ping from? A client in the new subnet? It is able to pull a DHCP lease correctly?

                  I changed the default TCP to ALL. It made no difference, though

                    Yes, client on the subnet. It's a static assignment.

                      Ok, so without DHCP it could be a layer 2 issue. Can we see screenshots of your interface and switch setup?

                        Show your rules on the interface..

                        Do you have the block rfc1918 rule on there, do you have the block bogon on there?

                        Do a sniff on the interface - do you see the ping come in??

                        Creating a transit interface is no different creating any other interface. If a device is connected to that network.. And you have the interface up, and the rules to allow it - then it would answer ping. If you can not ping, then you have a firewall rule blocking it, the connection is not active or not setup correctly for mask? Simple sniff will show you if your ping from ada is getting to pfsense.

                        Pfsense can not answer a ping, if it never sees the ping.

                          I will go set up a sniff.

                            Ok that all looks correct. What's in the LAN_IP_RANGE alias?

                                @peterlecki Yeah nothing jumping out at me wrong there.

                                So lets see the sniff do you see a ping to 192.168.2.1?

                                  Yeah I would also try enabling DHCP on OPT1 and setting a client to use it. That will prove you have a good layer 2. DHCP traffic is always allowed.
                                  If it then pings correctly the static client setup was probably incorrect somewhere.
