        @johnpoz Like you said, rules need to be inbound. So, for the LAN traffic reache VLAN 20 network, the source must be LAN in the VLAN 20 rules. In the other way, to traffic from VLAN 20 network reache the LAN network, the source must be VLAN 20 in the LAN rules.

        I'm so wrong like you said?

          n VLAN 10, to LAN interface.

          And what does that have to do with anything? You can run multiple vlans on a physical interface - what does that have to do with rules that make no sense?

          Do you not understand what a vlan is? Are you thinking you just going to run multiple IP ranges on the same actual interface?

          the source must be LAN in the VLAN 20 rules

          NO... Traffic is only filtered on the inbound direction.. How would the source IP be your lan IP inbound into the vlan interface from the vlan network? How? The rule makes no sense..

          Did you even read the first couple of sentences to what I linked too?

            Right, makes no sense, that's why I'm here, I need help to understand how to make it right.

            I need comunicate the AP-01 to Host 1, because the unifi controller. One way is ok, te return com is not working, can you help me?

              @rccruz-0 so your AP is on a different network than your controller? You would have to do L3 adoption..

              What do you not understand about how rules are evaluated?

              Your also forcing traffic out a gateway which is going to cause you grief as well, how would vlan get to your LAN, when your sending traffic out your wan gateway?

                I have two WAN Gateways, and I separate traffic in two as well.

                Gateway 1 for LAN traffic, and Gateway 2 for wifi traffic. Reading some article in web about this, they suggested set that rule to send traffic to a especific WAN.

                I understand what you said about send all traffic to WAN, but I think if a put that rule after the "no sense rule". That would work.

                  @rccruz-0 yes bypassing policy routing.

                  https://docs.netgate.com/pfsense/en/latest/multiwan/policy-route.html#bypassing-policy-routing

                  But again its just NOT possible that your lan net would be a source of traffic inbound into your vlan interface.

                    @johnpoz ok. Thank you. I understand that.

                    I will look for an alternative way to solve my problem.

                      What problem.. You have rules that would never work ever, because they just could never match.

                      If you want to allow or block traffic from lan to your vlan, then those rules go on your LAN interface with source LAN net..

                      if you want to block or allow traffic from your vlan to your lan, those would go on your vlan interface with source vlan..

                      For your AP to be adopted by your controller you would need to be on the same network.. Or you would need to use L3 adoption. And yes your rules on your interface(s) would need to allow the traffic you want to allow for the L3 adoption to work.

                        @johnpoz Yes, I understand those rules will never work. I'll remove then.

                        Now you talking. I'll set the rules you mentioned and post the result here.

                        Thank you !!!
