      Hi All,
      I'm new to pfSense but learning quickly. I have most of my lan on 192.168.1.0/24 network and a couple of devices on 192.168.2.0/24 network. I am trying to set up routing between the 2 but coming a bit unstuck. My primary gateway in on 192.168.1.254 and I have created a secondary gateway on 192.168.2.254. then added a default route to 192.168.2.0/24 via 2.254 GW. when I do a tracert each hop is stuck on the 192.168.1.254 GW.

      some pointers to get me on the right track would be greatly appreciated

        Post your firewall rules from each LAN

          Here is my firewall rule list. It is pretty basic at the moment for testing. I have even tried disabling the firewall completely under System/Advanced/Firewall & NAT

              Hmm, you only have one LAN interface in your rules tab, no OPT1 or so. Where do you connect 192.168.1.0/24 and 192.168.2.0/24 to?

              Each subnet must enter on its own interface, physical or virtual doesn't matter.

                That is not sound design. You don't put two IPv4 subnets on an interface like that in anything more than to maybe get through a renumbering transition. And even then you don't expect to be able to "route" between them.

                Use two interfaces or VLANs + a managed switch.

                There's a reason it is giving you trouble. You're not supposed to do it that way.

                  Thanks, that makes sense. I thought that by having a second gateway defined under system/routing/gateways I was effectively creating a virtual interface. So how do I create a virtual interface?

                    You create a vlan interface, and get a switch that supports vlans.

                      @johnpoz said in Subnet routing within the same LAN:

                      vice versa 😁

                        Or use another physical interface to another dumb switch.

                          Thanks guys,
                          I have started reading through the pfSense book and it is now starting to make sense. I can see that my original plan was a terrible idea, having multiple subnets on the same broadcast domain. I have started setting up using vlan tagging, but will focus on reading more before I get too indepth

                          Thanks Again

                            ou can tag all you want - doesn't mean anything if your switch doesn't support vlans
