      Ah, it looks like your LAN is also using 192.168.1.0/24?
      if
      That's a subnet conflict between WAN and LAN. You need to change one of those to a different /24 subnet. That obviously wouldn't be a problem if you had a public IP on WAN.

      However it's also different to when you set it up above where the WAN was using the 192.168.2.0/24 subnet.

        Ok I can change back to 192.168.2.0

        but we were running into the same issue there as well??

        Also - question -- when I create the interface connection and set up as a DHCP connection for the created WAN it seems to create some "dummy" gateway (that is greyed out and not available for use in the gateway group area). Do I just create an additional gateway ? Or how to handle that?

          Change it back. Any tests with the subnets conflicting will definitely fail an just confuse matters.

          We want to see DNS states on the WAN, without being NAT'd, and check if there are any reply packets.

          Is your outbound NAT still set to automatic?

              Here are some pics of where I changed back to 192.168.2.0/24

              And the 53 filtered state

                Sorry for being a pain in the butt -- but the really bad issue is that I can't seem to find a work around to get things working after the "fail" without literally rebooting the pfsense box!! Makess testing so hard

                  Ok, two odd things there.

                  You fail to get any ping replies from 8.8.8.8 when pinging from WAN. That should work.

                  There is DNS traffic from WAN directly but the states show it's still being outbound NAT'd from it's own address which should never happen.

                  On the outbound NAT page what rules are shown for the auto generated rules?

                      Hmm, that looks OK.

                      You have NAT states showing 192.168.2.2 being NAT'd to itself just on a different port. That normally wouldn't hurt DNS but it also shouldn't happen so it's unclear exactly what it's doing.

                      What happens if you reboot with WAN2 disconnected?

                          Ok. So there is no DNS traffic on WAN there.

                          There are clients that are configured to use 8.8.8.8 directly, 192.168.1.79 there, but it appears 8.8.8.8 is statically routed via WAN2 so it's failing.

                          Check the routing table in Diag > Routes.

                          That would usually be either the gateway monitoring or in the general setup if 8.8.8.8 is configured as a DNS server.
                          In your previous screen shots you have 8.8.8.8 used on WAN for both those but it looks like something has changed because it's being forced via WAN2.

                          Is 192.168.1.79 a client you're testing from?

                            So I am attaching the Diag > Routing table

                            I am attaching my current setup for my interfaces / gateways
                            And my current setting in the General Setup DNS page

                            Lastly I am attaching what I thought / hoped might work form a Protectli support page for setting up LTE modem on thier devices (in the Advanced Settings of the LAN Rules - forcing it to use the Failover GW

                            But this AM tested and it still failed -- AND had to completely reboot to get internet back up and going once the main WAN2 was plugged back in!

                                  also btw, I am not sure what .179 is
                                  it is not the device I'm testing form - but the network is large with probably more than 50 or 60 devices connected

                                  The routing table does not gicve the device a name (like many have) - it just gives a MAC address

                                    Ok you have some conflicting settings there. You have DNS servers set with specific gateways and you also have the same DNS servers set as monitoring IPs for the gateways. Both those thing add static routes and must match to work correctly.

                                    In your setup you don't need to set gateways on the configured DNS servers because they should work on either WAN and you're using a failover group as the default gateway. Additionally your are resolving directly so the DNS servers configured there are only used as a backup. However the conflicting static routes still breaks DNS for anything trying to use those servers directly. So remove the gateway settings from the DNS servers on the general setup page.

                                    If you add a failover group to the pass rules on LAN you bypass rules for local traffic. That includes DNS traffic from LAN side clients to the LAN interface. Otherwise it will be forced out of the WAN and never reach Unbound in pfSense.

                                      Ok. Thank you for advice
                                      I’ll change the DNS settings

                                      So do I leave the advanced LAN rule like Protectli recommended or change back to not using. I’m sorry I wasnt clear …

                                            Hmm, well I still expect to see the gateway monitoring IPs there, did you remove those too?

                                            Anyway that device at 192.168.1.79 should work fine trying to access 8.8.8.8 directly.

                                            I'm assuming (because it's the default) that your LAN side clients are being passed the LAN interface address to use for DNS?
