      You are not giving me the information I am asking for to help you find what you have configured wrong so good luck.  Maybe someone else's crystal ball is working.

      What information you want? Also, I disabled last two rules temporarily but still no ping.

        A diagram of your network including all gateways and downstream routers.

        Proper screen captures of your firewall rules on both the VLAN8 interface and all the floating rules.  For floating rules you need to capture the actual rule config screen so we get interfaces and directions on which the rules apply.

        If not screen captures then a detailed listing of all fields on the rule config screens.

        Look at the diagram in my signature if you need to know what information is necessary to properly help you.

        My pfsense dont route only local subnets but also subnets behind other routers

        We need to know what all that is - at least insofar as it relates to the 192.168.2.xxx subnet.

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

          This diagram is big work and I myself dont have complete powerpoint or paint about it made, only free painted picture in piece of paper. But I think this is not important because rules dont have any meaning when I want to ping locally connected computer. I think the problem is in pfsense VLAN communication with my L2 switch or VMWare Workstation. Altough before pfsense there, in the same place was Mikrotik virtualmachine and I was able to ping. In VMWare host I have also always removed VLAN support from network cards - when there is support for VLANs, then Windows removes tags, but if its disable, it dont. And with Mikrotik it worked, so its must not problem with network cards configuration.

            Okay. Good luck. If it's too much work for you it's certainly too much work for me.

              A few minutes with Gliffy would suffice for a basic diagram to show what you're trying to do.

              I'm guessing you can't ping the local IPs because of your policy routing rules. Policy routing forces traffic to the specified gateway, which won't get you a reply on local interfaces since you're sending it out to your upstream router.

                No, I disabled those policy-routing rules, I have no rules now, it dont change noting, still cant ping. Policy routing in pfsense dont force ping reply to other interface, because in pfsense policy routing is statefull. This was the most reason why I installed pfsense. This is unique. Previously I had Mikrotik. In Mikrotik and in all other firewalls policy routing is always stateless, and I have tested many fiewalls.
                The "reply-to" is also unique, to revert back to the interface where packets enter pfsense. This is because FreeBSD is more powerful than Linux. It just gives such extra features and possibilities. Most firewalls are Linux based and lack those possibilities. So, pfsense have very good potential to become good or even one of the best enterprise firewall. But you dont have normal documentation and it contains now too much bugs for enterprise work. This VLAN problem is BUG!!! I had there Mikrotik before and was not ping problem. This on VLAN stuff. Also I find out that captive portal dont work and was problem with switching off state checking (to switching firewall into stateless mode wasnt possible - rules just dont worked).  Those are all bugs and you cant fix them in this way, hoping only to forum where nobodi dont care. You must test this software yourselt or hire someone tester. …..Those bugs are not very catastrophy and I still proceed using pfsense, altough traffic lack into VLAN is little frustrating but most important functionality that Im interested are working (especially statefull policy routing and reply-to).

                  That's a hard statement. VLAN = layer 2, from what you describe I would tend to think this is a Layer 3 issue.
                  What about scanning that hand-made drawing? That will be the key to get better support, make people understand your setup.
                  Also, did you traceroute your paths? Some output from the issue would be nice. (you can insert images here)

                        This is not funny, I talk seriously. Usually some commercial company says thankx for that and fix the problem. This was happened before in reality. This is exactly the reason why freeware have so much bugs. Because they dont care and dont test software before release. Some companies even never give beta versions to public….. I say what is needed to do - just install pfsense, set up VLAN into some interface and ping it....that all, no more chemistry needed.

                          Yeah. It is extremely funny. Instead of wasting time with similar ridiculous claims, you could have produces the repeatedly requested network diagram about 10 times already.

                            You ping an IP,  not a VLAN. At best, you ping the SVI (which belongs to the VLAN) on your L3 switch, or an IF on pfSense.
                            Look, your setup seems… complex to understand by description.
                            Do yourself a favor, get that paper scanned, or take a photo of it. Or work on it in excel or something similar.
                            Keep it simple though, blocks with ranges, devices (with ip's an cidr), gateways. Shouldn't be that hard, and can serve for other things than just this topic.

                            IMHO that will be way more productive, and might give the people here the opportunity to help you out. (bug, design or config issue)

                                You dont need this diagram, you are not able anyway to fix this bug. To ask diagram for such simple bug only shows your uncompetency.
                                Only hope is when some developer sees this thread and she/he knows what to do and fix the bug, without any diagram. I searched internet and sees lots of forums where problems arise related to VLANs.

                                  There are lots of bugs in your head. No need to post to a forum asking for help when you instead of providing requested information keep posting useless noise and utterly ridiculous claims. There are people using hundreds of VLANs with pfSense in production. Quit this bullcrap.

                                    first user to ping a vlan??  What??

                                    Dude I ping between my vlans without any problems.. You have to allow it in the rules..  Out of the box you have lan.. the rules on lan (192.168.0/24) are any any.. So if you create a new opt interface for vlan 100 lets call it (192.168.100/24.  I will be able to ping anything on vlan100 from lan.  But vlan100 wouldn't be able to do anything because pfsense does not create any rules on opt interfaces.  You have to create them..

                                    So depending how you create them you would be able to ping or not ping, etc. etc..

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

                                    Look
                                    my lan is 192.168.9.0/24
                                    I have a vlan I call wlan 192.168.2.0/24

                                    As you can see here is client on lan pinging client on wlan

                                    You also have to worry about host firewall rules in another segment.  Out of the box for example a windows box will block ping from anything outside its network.

                                    I just do not understand how you get to such a state?  How is your touching a firewall and network equipment without basic understanding of the most basic of concepts?  This is your network?  And you don't have a drawing?  Or can not draw up a basic one in like 2 minutes?  You don't have to list out all 50 vlans if you had that many.. 2 would work for an example to get across what your issue is or isnt..

                                    Screenshots of your rules take all of 10 seconds...

                                    People can not help you without details.. And if your more fluent in another language which I take it english is not native for you - you might get better help on that section of board, might be easier get across your setup.

                                      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?

                                        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.

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

                                            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?  ::)
