      ping 8.8.8.8

      I see no losses running on the router:

        Does not seem like I am seeing losses all the time, maybe just some ISP issues but not ongoing ?

          Seems like an ISP that sells 'n' times a "1GB fiber up-link" but they haven't a n x "1GB fiber up-link" from their neighbourhood router upstream, to the net. Thy're overselling (they all do).
          Result : upstream gets full (everybody wants it's "1GB fiber up-link", espically at 08h00 PM, low priority protocols get dropped like ICMP.

              Good !
              Right now, your ISP is actually quiet good.

                I'm experiencing similar issues. It is even worse ... from time to time the interface is not even recovering. See my description below posted to support:

                In two locations I have installed the SG3100. In one locations, there is a gateway group with two WAN connections. The other location has only one WAN connection.

                On these two devices I discovered some strange behaviour with the gateway monitor which is pointing to Google DNS servers (8.8.8.8) or Quad9 (9.9.9.9). These are both multicast IP's.

                Case A/ 2 WAN connections with primary and failover WAN

                At a given moment the primary WAN failed due to a package loss towards 8.8.8.8. The secondary takes over as planned and no network interruption seen, but at no moment (in a period of several weeks) the primary became online again (although of course the 8.8.8.8 was perfectly pingable from any device in the network). The only way I could re-enable the interface was going into the configuration and force it online. (See 2 attach starting with 2WAN_ => you see gateway with 100% loss, traffic dropping to 0 and other interface taking over.)

                Case B/ 1 WAN Connection

                At a given moment the gateway monitoring indicated major packet loss and the gateway was "offline". However, I didn't notice this one while working on the network, so even if it was "offline" it kept working, which I found strange. Again I tested the ping from a device on the network which worked perfectly. I did the ping test using diagnosis tab in PfSense GUI, and to my surprise it indicated 100% packet loss ... other pings worked well. Also here, I had to go to the config to force the interface online. This resolved the ping issue as well using the diagnosis ping option. However, as stated, even with the gateway "offline" I could still work.
                (Attach: 1WAN_GatewayDown_Keptworking => You see the gateway goes down but there is still traffic). But key thing here as well ... why didn't the ping recover ?!

                Case A/

                • Primary interface goes down due to 100% package loss for ping

                • Secondary takes over for several weeks (till manual intervention)

                  Similar happened to me. I'm using SG-3100, sometimes GW shows offline but still able to work, on other occassion completly dropped. I've rulled out ISP (checked my mode, connected directly to it and no problems).

                  "Also here, I had to go to the config to force the interface online. This resolved the ping issue as well using the diagnosis ping option. However, as stated, even with the gateway "offline" I could still work."
                  Can you elaborate on what you did? I'm new to pfSense and trying to learn :)

                  I've checked my system log, it looks like ppp is tripping?

                    I have changed my monitor ip to 8.8.8.8 and so far don’t see any losses in 2-3 days.

                        I don't know :(

                        Frankly, I did not pay much attention

                        This is what I see in the logs now:
