      I searched internet and sees lots of forums where problems arise related to VLANs.

      Yeah mostly because the people having such problems don't know what they are doing.

      You have it in your head that it's a "bug" and can't get out of that mode.

      At a minimum, post the EXACT STEPS to take to reproduce "the bug."  It's the first thing anyone in development will ask for in the bug report.  If it's a bug in the VLAN code it ought to be easily reproducible on a small bench/lab setup.  Or is that too much work too?

        Post up your lan rules, post up rules of one of your vlan interfaces.

        I have in pfsense in every interface only one rule that allows all connections, all protocols. In interface configuration there is only IP and gateway to next hop. Interface is assigned to VLAN8 and VLAN8 is assigned to physical interface. This physical interface is VMWare Workstation virtual network card that is connected to virtual switch. Virtual switch is binded to windows2008 host physical network card where is allowed only vmware binding protocol. Then this network cat5 cable goest to TP-Link L2 switch, then to other TP-Link L2 switch and then into TP-link wifi router WAN. WiFi router can ping pfsense interface but pfsense ping tool cant ping WiFi router WAN.

          Probably because, as has been said many times, your policy routing is probably sending the pfSense-originated traffic out some other gateway because that's what you told it to do, while pinging into the pfSense interface is working because of reply-to for the return traffic. Since you refuse to post details, that is just a guess.

          Rules on the VLAN interface have nothing to do with traffic originating from pfSense.  You also have floating rules which CAN affect traffic in the outbound direction of an interface but you refuse to post actual details about those, too.

            Or he's blocking the traffic on the unknown wifi router's WAN firewall (which shouldn't be doing any routing in the first place and should most likely be connected via a LAN port). Or… pfS FW rules requested -> nothing. Diagram request - some messy setup description posted instead. Logs? Nothing. Who needs any info after all. It's pfSense bug with VLANs, 333% -- because noone ever pinged a host on VLAN before!!!

            Why are we still wasting time here?  ::)

              Lan interfaces would not have gateway.. What do you think is the next hop??

              I'm just here for your witty comments dok – you always make every day brighter with your wonderful way with words and cheerful disposition towards incompetence..  I don't know how you do it, but pretty much every post of yours puts a smile on my face ;)  Another applaud for you btw.. 300 is just around the corner.

                WiFi router can ping pfsense interface but pfsense ping tool cant ping WiFi router WAN.

                You're still very sparse with information  ??? When you say ping the Wifi router WAN, is that an ip in the same subnet as where the IP of pfSense in vlan 8 resides?
                Repeat test with pfSense: Diagnostics: Traceroute, and post output please.

                    Agree  ;D nearly fell of my chair when I read your post.

                    Anyhow, it's an intrguing design with enough routers to keep one busy. I've read this for the fifth time or so trying to see the picture (he's refusing to draw  ::) ):

                    @magnifico:

                    They are all LANs, 5 interfaces, all equals, for LAN subnet communication. When I dont set gateway, then I cant use policy routing, but pfsense is set up exactly only for LAN subnet policy based routing (source and destination important in routing decision). Also when I dont have set up gateways, then traffic dont come back into the same interface as it enters pfsense. My pfsense dont route only local subnets but also subnets behind other routers….........To internet I have 2 subnets before final routers, 192.168.3.0 and 192.168.10.0. Policy must choose gateway depending on source IP. For LANs I have 3 subnets 192.168.2.0 192.168.1.0 and 192.168.4.0 Between pfsense and computers I have more routers. Some 192.168.12.0 subnet computers reach pfsense through  192.168.1.0 subnet and some through 192.168.2.0 subnet. Usual routing table is unable to choose interface because they are all 192.168.12.0 subnet computers, going to internet through different LANs and different WANs.

                    And now I'm in doubt my request for traceroute is going to bring anything usefull. I also fail to see why he thinks it's a vlan issue, this is clearly routing stuff. And not even sure one can accomplish what he wants by using pfSense?

                    Maybe we should ask for a drawing  ;)

                        Well… Not always true  :o

                        If it is connected to other L3 switches or networks for which pfSense is NOT doing the routing (there are more subnets to reach on those interfaces), that would be needed.
                        So the next hop for the LAN could the SVI of the vlan (on the L3 switch), and that is not on pfSense (but the subnets are known by pfSense (System:Routing:Routes). And so on.

                        One thing is true however. You cannot ping the vlan  ;D ;D  (sorry, couldn't help myself  8))

                        So magnifico, how about a drawing?

                          Problem is resolved, thanks all for help and still never undervalue bugs. There are still lots of bugs. Captive portal example dont work but no problem, I use Kerio portal, its better stuff….The problem with ping wasn in WiFi router, there was firmware upgrade before......And also before I noticed that switching off state and making double rules for both direction wasnt worked in first try, but this is also not very important, usually I like to use statefull mode....Pfsense is good, but it can be even better when developers write documentation, test it more and then it can be usable also for enterprises. So, good luck and thank you all, I hope I can now configure it myself in a while.

                            Because your wifi router should NOT be routing, as I already told you. It should be set up as a dumbed-down AP with no DHCP, no firewall, pretty much everything turned off, and connected via LAN to a switch.

                              So your "bug" was actually the config in another device and you still blame pfSense, the pfSense Developers, and pfSense documentation.  Nice.

                              Is there a bug in pfSense VLANs? Inquiring minds want to know.

                                    That would not be a "gateway" that would be a ROUTE you set to the specific network..  When you add a gateway to an interface it becomes a WAN interface..

                                      No, it doent become WAN interface. What is exactly "WAN" interface? What is WAN? Do you mean Internet? No, I example dont have any internet in pFsense, Internet is long-long away from pFsense, there is only LAN, bottomless LAN with no edge….....In pfsense wiki (altough its no any documentation, its crap) I was readed that when I want to use policy routing, then I must put gateway address into interface where this gateway locates. First I tried without this, not worked, then readed about that and then worked. Second rule is when you want use reply-to, then rule must be set in interface tab, not floating tab. Of course all those requirements are only bad GUI implementation. Not at all all peole know this without first experiment and read about it. Its just big mess and not at all good practice to make administration interface. Those requirements are stupid, all this can be mede automatic and no more mess, forums questions and misunderstandings. ...p.s. Switch are usually L2, not L3

                                        P.S. The WAN is the interface with default GW. You cannot have a pfSense box without one.  ::)

                                          Or you mean "WAN" not Internet but instead outbound-destination direction related to connection state. So, this should be bad restriction when router can work only one direction.
