        @jogovogo is the mask correct on the client/in DHCP settings?

        Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
        When upgrading, allow 10-15 minutes to reboot, or more depending on packages, and device or disk speed.

          I'll add that behavior to the "VLAN switch isn't setup correctly" list.
          The initial client initiated DHCP traffic is "broadcast" (probably not related).
          You have activated the DHCP server on OPT1 ?
          On the OPT1 connected device shown above, you can
          (windows example) :

          ipconfig /release
          

          and

          ipconfig /renew
          

          ?

          Edit : and where are the logs ??

            Hello, that works automatically. I've already made it so that it receives an address from the DHCP area right away after the release.

            This is the case with two different machines.

              That's what you want to happen.
              Never ever believe the "system". As the network admin, at all times, fact check everything ๐Ÿ˜Š

              For example, red flags were already shown : The IP (192.168.151.11) looks ok. Mask and gateway also. But the 8.8.8.8 DNS is a fail.
              So, my thoughts : some one set them up statically ? Or entered 'strange' settings in the DHCP server ?

                The 8.8.8.8 is only for testing; even if I use the machine to set the IP and as a DNS and gate, the 192.168.151.1 does not work.

                  My first surprise is that I'm now on the firewall, but why?

                  But still no access to the Internet...

                    Hello again!

                    The issue has been resolved, simply, by restarting the DNS resolver.

                    I just had another one, though; perhaps you could also respond to it?

                    NAT and VLAN

                    The port 2413 should be seen on 192.168.151.10. The corresponding rule is created automatically. Unfortunately, it does not function.

                    The "LAN " operates it without any intervention.

                      but:

                      ping on the address 192.168.151.1 also fails

                      ...is not related to DNS.

                      In any case restarting DNS is necessary if a new interface has been added, because unbound didn't know about that IP when it started.

                      re: NAT, often the firewall on the server isn't set to allow traffic from any IP, only the local subnet or RFC1918.
                      https://docs.netgate.com/pfsense/en/latest/troubleshooting/nat-port-forwards.html may help.

                      Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
                      When upgrading, allow 10-15 minutes to reboot, or more depending on packages, and device or disk speed.

                        Hello, many thanks for your prompt response!

                        Indeed, ping has nothing to do with DNS.
                        I didn't notice it because I didn't even attempt it on one machine.

                        This is working now as well. We used pfBlockerNG, and the opt1 still needed to be defined in the Outbound Firewall Rules. Then once update via cron and now it works!

                        cheers
