      If you want a LAN subnet of 192.168.10.0/24 then your pfSense router's LAN interface needs to be in the 192.168.10.x range... not in the 192.168.1.x range.

      Like @viragomann said, it sounds like you've got the PC in one subnet & the router in a different one.

      Is the 192.168.1.100 supposed to be your WAN? This doesn't make sense to me

        According to the sketch, there's a router in between. That should allow pinging between subnets. Also, the OP said he couldn't even ping the router, IIRC.

        PfSense running on Qotom mini PC
        i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
        UniFi AC-Lite access point

        I haven't lost my mind. It's around here...somewhere...

          @JKnott @lburr Nah guys I have a pfsense router connected to the internet then on
          LAN - I Have an ISP provided router - This Assignment has a static ip of 192.168.1.1
          OPT - I have my PC - This assignment has a static ip of 192.168.10.1

          My PC = 192.168.10.100
          My Router connected to the PFSENSE = 192.168.1.100

          My PC can ping both assignment static IPs i believe they are called gateways (192.168.1.1 and 192.168.10.1)

          Hope this clears things up

          Thanks

            What sketch? I only see a mess of 3-lines ASCII.

            Useful ASCII sketches are prepared for copy&paste here: https://forum.netgate.com/topic/19017/netzwerk-diagramme-zum-einfügen-in-eigene-posts
            Don't worry it being the German part of this forum. The beauty of a sketch is that it's universal to understand.

              @jahonix I'm glad I wasn't the only one confused by his sketch, using a sketch like your link shows is way easier to understand. ☺

                How are you testing this ping and what's the actual returned error?

                pfSense should always be able to ping those as it has interfaces in each subnet. You would have to try quite hard to block that with firewall rules.

                  That https://textik.com is slick as shit! Added to my toolbelt links. Thank!!!

                  That will make for some really nice ascii art network diagrams.

                      What is this downstream router you have attached to pfsense? Which you have this other network connected to. If its in your 192.168.1 network then you have a asymmetrical problem that will happen for sure on the return traffic from devices in the 192.168.10 network.

                      If you have a router/L3 switch doing routing connected to pfsense via opt interface then the network should be a transit network. Not your normal lan network with devices on it.

                        I had ASCIIflow in that german support topic as well, but after trying both, it certainly lacks a few functions compared to textik. Textik handles links/lines between boxes and they stay linked/sticky whereas asciiflow doesn't have some sort of linking functionality :)

                        Don't forget to upvote 👍 those who kindly offered their time and brainpower to help you!

                        If you're interested, I'm available to discuss details of German-speaking paid support (for companies) if needed.
