      @stephenw10 I will get the system logs. We just noticed this problem when the whole company have no network connection. I mean there are PC that shows "No internet access" but they have actually, it is just very very slow even file server takes a lot of time to load from each PC. When we check the firewall, it already have this error, so we restore the last backup but still not working. During that time, the dashboard also shows "Unable to check updates". When we try to remove or reinstall some packages, it shows "Another instance of pfSense-upgrade is running."

          That sounds more like an actual upstream connectivity issue. Perhaps the ISP is passing you an IPv6 address and isn't routing it correctly. That can present as delays when clients have to try IPv6 and wait for it to timeout before trying IPv4.

            @stephenw10 Do you mean they do changes on our configuration? Something like that? Because we already conduct internet speed test and seems no problem with their end. Does it mean this error the system is showing has no bearing from what we are experiencing right now?

              Which interface is re2? Are those MAC addresses known devices?

              Try running at the command line (not in the gui): pkg-static -d update

              Does it fail to connect to the pkg servers? How does it fail?

                Actually, it has no MAC address declared. It should be the MAC address of the firewall itself or the MAC address of the router or hardware provided by our ISP?

                Try running at the command line (not in the gui): pkg-static -d update

                Does it fail to connect to the pkg servers? How does it fail?

                I'm sorry, cannot provide you answer right now because I'm just remoting. I will try tomorrow in the firewall itself.

                  Those MACs are from LAN side clients that appear to be moving. You might have some IP conflicts there if any of those hosts are using static IPs.

                  You can connect to the firewall using SSH remotely if you want to test that.

                    You mean there are devices that uses the same IP? Basically, we encoded to DHCP Leaeses or Server each devices that is handled by IT like this:

                    dhcp-server.jpg

                    Or you mean there a device that uses the same IP used by re2 which is 192.168.20.254?

                    You can connect to the firewall using SSH remotely if you want to test that.

                    I will research about SSH, this will be so helpful for us.

                      I mean more than one device no the LAN trying to use, for example, 192.168.20.130.

                      There are some legitimate reasons why you might see that. But if none apply to you then you might have a real conflict in which case I'd expect to see some problems connecting from those devices.
