      That is still not tagging LAN with VLAN ID 2.

      Create VLAN 2 on interface igb1

      Change the Network port for LAN to VLAN 2 on igb1

      Patch igb1 to a trunk port with VLAN 2 tagged on it.

      Be sure the firewall rules on LAN pass the desired traffic that will be inbound to it.

      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        I re made the vlan to vlan10 on the switch and in pfsense.

        I dont think i'm understanding. The opt1 port is on 192.168.2.1 and thats the network i need to give ip's to the switch to my hosts.

          Please describe EXACTLY what interface you are talking about and please post the screen shots of Interfaces > Assignments and the switch port you are connecting to pfSense.

          Setting the PVID (native) here says you want the traffic UNTAGGED on that port:

          interface Ethernet1/40
            switchport mode trunk
            switchport trunk native vlan 10
            switchport trunk allowed vlan 1-10

          If it is tagged on one interface it has to be tagged on the other.

            I re configured ethernet 1/40 and removed trunk native line.

            I will attach pictures of the tabs and a diagram of how things look.

            Thanks

              How is the switchport connnected to cxgb0 currently configured?

              What, specifically, isn't working.

              You are going to have to be very specific to overcome this language barrier.

                The csgb0 port is connect to the trunk port on the switch ethernet 1/40.

                Whats not working is i cant ping the router from the switch and the switch is not getting a ip address from pfsense.

                Now i just did a test about hardware problem. The 10gb nic i have is a Chelsio T320-CO-SR.
                If i'm correct if i connect cxgb0 directly into one of my hosts that port should get a ip address from pfsense.
                I did that and i got no ip address.
                I tried the same thing and igb2 which is opt2 on my router and connected it into my host and i got a ip address.

                Could this because of a hardware fault?

                  It could be a hardware fault but there is really no way to know with the information being provided.

                    I'm i correct on how dchp should work when directly connecting a end device?

                      I will ask one question at a time so we don't get lost…

                      What pfSense interface are you talking about? LAN, OPT1, or OPT2?

                                      OK then something connected to an access port on VLAN 10 on the switch should get an IP address.

                                      If not you have to figure out why not.

                                      I have found looking at the mac address table on the switch for that VLAN is a good place to start.

                                      You could also send the output of these commands entered into Diagnostics > Command Prompt (or run from the shell)

                                      ifconfig cxgb0

                                      ifconfig cxgb0.10

                                        That's the funny thing. I don't a single ip address to the switch.

                                        There are those commands ran.

                                          That looks fine.

                                          You need to look closer at layer 2.

                                          What mac addresses are on VLAN 10?

                                          Probably something similar to show mac-address-table

                                            That looks fine.

                                            You need to look closer at layer 2.

                                            What mac addresses are on VLAN 10?

                                            Probably something similar to show mac-address-table

                                            Vlan 2 is vlan 10 same config. I tried to redo it again.
