      Yup... So lets see your rules on on vlan 5 again... And do you have any rules in floating?

          So your blocking it with pfblocker... Disable those rules on floating as test!

          That firehol list contains rfc1918 address space!!

            Ok I disabled those rules and disabled pfblocker for the time being.

            I set those rules up when I set up pfblocker but I was never 100% competent on how it is setup, I only set it up about two weeks ago....

                  Well your firewall rule that allows all of IPv4 show hits... And your seeing the traffic actually hit pfsense vlan interface... You were sniffing on the vlan interface right!! not lan..

                  So lets see your routing table..

                  Unless you where not sniffing on vlan 5 interface it makes no sense to be honest..

                  Is pfsense a VM? Or this is a physical box... What is the nic of this box? Why does the mac of the 5.1 not show as known company?

                      Well that looks correct.. you have 192.168.5 and using the interface..

                      And it was seeing traffic - your not running any sort of IPS are you?

                      Can you post output of

                      cat /tmp/rules.debug

                            So maybe its just an issue with this nic and vlans

                            perhaps the card that I bought off Amazon does not support VLAN's, although I presumed it did. Also I saw that pfsense only shows interfaces that VLAN's can be created on so if the card didn't support VLAN's it should not show in the pfsense drop down.

                              You've made a lot of changes, I suggest you reboot the firewall to make sure the pfb/snort is off.

                                Well I am out of ideas to be honest... You say your sniffing on your vlan, and seeing the ping request.. Your rule you posted shows your allowing it... And your showing hits..

                                So makes no sense..

                                But your running IPS, and you had pfblocker with rules that would block rfc1918 space, etc..

                                Your nic is some no name???, never heard off - and its mac address does not even lookup... So maybe its just an issue with this nic and vlans... Lets see a ifconfig output from pfsense. I want to see what is showing for options on your igb1...

                                example - here is an interface I am running vlans on.

                                Only other thing would be to run tcpdump on pfsense with -e flag so you can see the tagging is happening or not happening... Maybe its answering without the tag???? So your sniff on vlan wouldn't show it - that is guess..

                                But sure a reload of your rules, or reboot couldn't hurt.

                                From pfsense - sniff on your vlan 5, and try to ping your client 192.168.5.50..

                                  So maybe its just an issue with this nic and vlans

                                  Perhaps it is, I presumed the card that I purchased off amazon supported vlan's and the pfsense drop down showed the card as an interface that could create vlans on...

                                  just to recap the NAT automatic rules have added 192.168.1.0/24 and 192.168.5.0/24

                                  can I just be sure that I'm not missing a specific mapping that needs to be added???? like you have said before would the automatic rule be enough???

                                    Your nat rules have zero to do with pinging 192.168.5.1..

                                    Who makes this card exactly??? 6c:b3:11 does not show up as vendor .. ipolex?

                                    It really makes no sense at this point... Have you rebooted? And you disabled snort and pfblocker... What is looks like from your sniff is firewall not allowing the traffic..

                                    edit: Why do you have this on your vlan interface??

                                    STATICARP

                                    Do you have this enabled???

                                    enabled.jpg

                                    OMG dude - did you just click every possible thing there is to click without clue one to what any of it does??? Why would you click that???

                                      Not sure how accurate this information is but a Google search shows that his NIC is made by the following company in China. Never heard of them. Maybe this NIC is not compatible FreeBSD 11.x?
