      I have similar issue, 2 vlans, 103 and 203, I was trying to ping from iphone to printer or windows to printer or windows to iphone, no luck. All should be good imho. I even added extra rules to pass traffic between vlans but based you what you have here this is not needed.
      rules for 103

      same logic for 203

      Diagnostics is a pass, weird

        VLAN103 will never see traffic sourced from VLAN203 coming into it. That first rule is useless (note the 0/0 counters there since it's impossible for traffic to match it). If you want 203 to be able to ping 103, put the rule passing that traffic on 203.

        That ping works because you are sourcing it from the firewall.

          Both vlans 103 and 203 have imo correct rules

            your forcing traffic out the gateway how can traffic from 1 vlan get to the other vlan - via that gateway your sending it out of.

            If you want vlan 103 to talk to 203 then you need a rule that allows said traffic before you send traffic out some gateway. On the vlan 103 interface, and vise versa for 203 to talk to 103

            You also have to be concerned that the device your trying to get to on the other vlan allows access from the source network IPs - ie the devices local firewall if any.

              @johnpoz said in Inter VLAN routing:

              The thing is I don't have internal gateway defined like 10.103.0.1 or 10.203.0.1, all are gateways form public blocks. Can I define internal one and use it then?

                DONT assign a gateway... Just leave it the default * so it can use its internal routing tables.. Which is knows how to get to networks its direcctly attached to, ie the vlan 103 and 203.

                Create a rule on vlan 103 that says dest vlan203 net and does not assign it a gateway. Put this rule ABOVE the rule where your forcing traffic out that failover gateway.

                Reverse that for your vlan 203 interface

                  Yeah I didn't notice the policy routing in your rules. Sorry.

                      And does the other end have a firewall? Windows machines for example out of the box will not answer ping from something not on its local network.

                      Simple do a sniff on the vlan 103 or 203 interface in pfsense when you ping from the other vlan - do you see the request go out.. If so and no response then its the host..

                          Does the printer even have a gateway set... Have seen this too many times to count there the printer does not have gateway set so you can only talk to it from the same network.

                            Yes it does have properly gateway, it was manually changed with IP and subnet.
                            In my case it is carp IP gw 10.103.0.3 .1 is master .2 is slave

                              Then I suggest you sniff... This is not any difficult here.. You connect a vlan, you allow it from the other vlan it works.. Sniff sure the ping is being sent/seen on pfsense ingress interface, and validate it going out the egress interface towards the printer. Maybe someone F'd up the mask on the printer or typo's the gateway.

                                Diagnostics > Ping Set the source interface to the other VLAN. Ping the printer. PCAP on the printer VLAN.

                                Pretty much guarantee that you will see the requests going out and no reply so you will need to look at the printer configuration.

                                    So great - are you sure your client you were pinging from pings actually got to pfsense?

                                        That is what is happening when the real client pings printer while I capture vlan 103 and printer IP 10.103.0.11

                                        14:55:21.548856 IP 10.103.0.11.5353 > 224.0.0.251.5353: UDP, length 184

                                          that is NOT a ping.. that is a mdns query to the multicast address.

                                          Pfsense not going to do shit with that.. Unless you had avahi installed and configured.
