      @Derelict Thank you very much for trace-route. But why can I ping 192.168.1.1 from WirelessNetwork. I think anything from WirelessNetwork net to LAN net should be blocked by default.

        Well, if you want to BLOCK traffic on from Wireless network to LAN net then BLOCK it. Don't block traffic with a pass rule.

        Add a rule above what you have that blocks traffic to destination LAN net above what you have and see if the behavior changes.

          @Derelict Great, thank you. I created a BLOCK rule and it's working.
          Now I am backing LAN ports can't reach LAN gateway problem. Looks like fixing problems with WirelessNetwork doesn't fix LAN net. ๐Ÿ˜ž

            @stephenw10 I connect one of the Win10 computer to LAN1 port and Switch setting is here:

            aec0ce2b-b734-4276-af03-1f1a2eff37a4-image.png

            It's getting correct IP address from LAN DHCP 192.168.1.115, but is't offline
            2bcf2e02-11c1-40a7-888b-dbdf8aab579a-image.png

            I started Packet capture on LAN interface for IPv4 only.

            Looks like LAN can receive from Win10 computer but never reply.

              Ok that is good info, now lets see your actual switch config.

                    See that tab you showing the ports - hit the vlan tab.. lets make sure nothing messed up there

                    switchports.jpg

                    That is the default settings, from one of my 3100s

                    You don't have any rules in in your floating tab do you? And for good measure lets see the routes.. under diag..

                        Have you tried reloading the firewall rules? Or I take it you have tried rebooting it? ;)
                        Try changing the IP to say 192.168.2.1/24 on the lan interface?

                        Everything looks right..

                        Are you seeing any errors on the interface, in the interface status?

                          Looks like you have pfBlocker installed. Let's see the floating firewall rules. You maybe need to edit them to see all the info.

                          That can block and not log traffic in LAN if it;s not configured correctly.

                            He stated he has no rules on floating.

                            You didn't setup any port forward rules did you?

                            I would like to see the full output of the rules to be honest

                              @johnpoz No, zero errors on LAN interface and I did tried different ports. And I did tried change LAN IP to 192.168.10.1/24, still not working.

                                    It's not rules (though it looks like you are still using a ! LAN net rule for some inexplicable reason.)

                                      @Derelict Sure, here is my VLAN:

                                      Here are ports:
                                      edcd6726-bc36-48a9-8489-e1364d35ea3e-image.png
                                      And I disabled all firewall rule here:
                                      ec21994f-994c-4954-9eb8-a658f3dd7ec8-image.png
                                      I uninstalled pfBlocker and disabled OpenVPN. Then reboot the firewall but still no luck.
                                      Next thing I am going to try is reset to factory default.
                                      But if that still not working I think it might be the hardware problem.

                                        Disabling pf will, as it says there, disable NAT so you will be unable to connect to any public IPs from any internal interface.
                                        You should still be able to connect to LAN though...

                                        It seems unlikely to be a hardware issue since clients on LAN are still able to pull a DHCP address, traffic is able to flow both ways for that to happen.

                                        Do you see the connected LAN client in the ARP table? (Diag > ARP)

                                          That is a very good point... Do you maybe have anything with static arp setup?

                                          When you ping pfsense, from you pc... What does pfsense show in its arp table for this client IP.. Does the mac in the table match?

                                          where is that block ! mvneta1 inet from 192.168.1.0/24 to any coming from?

                                          Make sure you remove any ! rules...

                                            @johnpoz said in Netgate SG-3100 LAN ports cannot go through LAN Gateway.:

                                            where is that block ! mvneta1 inet from 192.168.1.0/24 to any coming from?

                                            That's a system default rule. It blocks traffic from an assigned subnet arriving on any other interface.
