      @johnpoz The switch is LAN1 active with default config. The interface assignments are

        maybe some antivirus/firewall on that windows 10 machine that can block it?
        is the network set as public instead of private ?

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

          but the online status is offline.

          That means it can not get dns..

          Well if you can see the correct mac and get an IP - then yeah I would think something wrong on the machine itself if plugged directly into the 3100 switch ports, and nothing else connected. Simple enough to sniff on pfsense - while your pinging, so you see the pings or not?

            @johnpoz I disabled all firewalls in Win10 computer and still can't ping. And no I can't see any pings or traffics from win10 computer to pfSense in firewall logs.

              Hmm, curious. Are the switch settings in the SG-3100 still at their defaults?

              Can you ping out from pfSense to the Windows host on LAN?

                @stephenw10 Yes, the switch settings for SG-3100 are their defaults. And no I can't ping Windows host from pfSense (connection timed out.)

                  Hmm, sure behaves like a subnet conflict, like there is something else there responding as 192.168.1.1. If that was the case I would expect to see a load of errors in the system log though.

                  Try running a packet capture on the LAN from Diag > Packet capture whilst pinging from the Windows host. Do you see the pings arriving?

                    @stephenw10 I also did try to change IP address for LAN to 192.168.10.1. And Windows computer get correct IP from DHCP 192.168.10.100. But still can't ping LAN.
                    I will try to run packet capture on Monday and see what will happen. Thank you so much.

                      I also found a very strange thing that when I connect Win10 computer to WirelessNetwork port, it gets correct IP address and gateway
                      af8b64b5-7cac-4795-a129-a34377eee2c1-image.png
                      But it also can ping LAN 192.168.1.1
                      86bf2a30-449f-4f13-ab04-782463ae1bb3-image.png
                      Even I have this rule in WirelessNetwork
                      481dfcf1-cc5a-4413-ad3d-657b67e898e0-image.png
                      Also when I tried to get route from 192.168.30.52 to 192.168.1.1 in Win10 computer
                      290bbb19-b302-46d7-bcef-00fd9f073cc0-image.png
                      It seems like it access 192.168.1.1 directly not through it's gateway 192.168.30.1
                      Can anyone help to explain these weird phenomenon? Maybe by fixing this will fix the LAN ports can't reach LAN gateway problem. Thanks.

                        Not necessarily.

                        192.168.1.1 is still only one hop away since that address exists on the same hop you reach at 192.168.30.1. It is free to respond to a traceroute using that address.

                          @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. 😞

                                @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.
                                13107108-2369-4f78-a4be-7c3e519c7064-image.png
                                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..

                                          @johnpoz Yes, my VLANs setting are same as yours. And I don't have rules in floating tab. And here is the routes:

                                            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?
