      I had the same problem after an upgrade (both on nanobsd and hdd installation).

      I solved by going to 'Interfaces >> LAN' and change the gateway to 'none' and LAN can access internet. I do not know whether this is the way to do or not?

        There should NOT be any GW for non-WAN interfaces.

          Thanks for confirming. :-)

            Indeed. We don't know Ramy's exact setup but since his default gateway was set to 192.168.1.1 it seems likely that he set a gateway on LAN which is incorrect. However his screen shot shows no gateway set on LAN so perhaps his more complex WAN setup caused problems. It would be interesting to know how the default gateway ended up set like that if no gateway was ever set on LAN.

              @stephenw10:

              Do you have a default gateway set? System: Routing: Gateways:

              That was the problem! The default gateway was 192.168.1.1, I've changed the default gateway to the gateway of my provider and it worked!

              Shouldn't the gateway there be "dynamic", as WAN goes over PPPoE? In theory, the ISP could change the default gateway….

                Exactly, it should. However since the WAN is PPPoE over VLAN in this case perhaps he needed to manually configure some things that ended up overriding the ISP supplied details.

                  I've attached a screenshot of "Routing > Gateways". Somehow GW_LAN was set as default, I've set WAN_PPOE default and the problem was gone. The WAN gateway is dynamic.

                    I've noticed when you edit the LAN GW (e.g., change the monitoring IP), it somehow makes itself default. I deleted the LAN GW altogether and have had zero issues since then.

                      As mentioned above you should not have a gateway on LAN.

                      The only time you would ever want that is if you have some downstream router with another subnet behind it such that pfSense needs to know where to route traffic to get to it.

                      Usually you only see a LAN gateway in the gateway table like that if you have set one on the LAN config page. Your screenshot in the first post shows no gateway set but perhaps you set one subsequently? Either way make sure it is not set now and remove it from the gateway table.

                        I haven't set a gateway on LAN after I created this thread. I don't know why it was there.

                        I've removed the gateway.
