      Hi,

      we are experiencing a difficult period in Italy right now, where most of the people is forced to work in home office.

      Currently I´m experiencing issues with my internet connection resulting in annoying voip lags while chatting over MS Teams with and without screen sharing.

      in the last day, I experienced some packets lost from my desktop client, while pinging 8.8.8.8 which i simply explained by a "general internet overload" in Italy.

      Today the situation got worse, therefore I performed additional test. I have executed a ping to 8.8.8.8 from my desktop pc and the pfsense box over ssh at the same time, while running a speed test on my desktop´s pc browser.

      Following unexpected result

      • Desktop to pfsense ping: 100% fine, no packets lost. response time always < 1ms
      • Pfsense to 8.8.8.8 (ping executed in ssh shell): 100% fine, no packets lost. response time around 40ms (normal for my radio relay provider). Ping increased to about 55ms while upload speed test was performed.
      • Desktop to 8.8.8.8: Fine only by 88%, because I lost 12% of the packets :)
        obviously all pings where executed at the same time from the desktop PC

      My first Idea was that maybe my TPLink switches are rubbish (TL-SG108 and TL-SG105), so i switched my desktop from LAN to WLAN (TPLink EAP225) . Same result: some packets are lost.
      Restart of pfsense box, nothing changed.
      Performed another test with my MacBook pro. Packets lost as well.
      Result: Pfsense box itself doesn´t lose any packets, but connected clients do.

      I´m running out of ideas now. I don´t expect pfsense to be so silly to lose packets. There must be an issue in my configuration which I´m unable to recognise at the moment.

      Pfsense configuration overview:
      WAN over pppoe
      Igb0
      VLAN 1 on igb0 interface for LAN
      VLAN 29 on igbo interface for LAN IOT
      Igb1
      WLAN on igb1 interface for WLAN
      VLAN 20 on igb1 interface for WLAN IOT

      Firewall rules:

      • almost nothing, exempt IOT networks forbidden to talk to "trusted networks"

      No traffic shaping.

      • Traffic Limiter for WLAN IOT to limit the traffic to 3500 kbit/s down and 500 kbit/s up

      Installed packages:

      • Avahi
      • openvpn client export
      • pfBlockerNG (working with floating rules)

      Any help is appreciated.

      PS: Pfsense is running on an APU.4D4. CPU never goes above 20%

      Thank you and best regards from Italy

        Hi guys,

        I don´t know why but I´ve overlooked following article from the official documentation:
        https://docs.netgate.com/pfsense/en/latest/hardware/troubleshooting-lost-traffic-or-disappearing-packets.html

        Currently it seems, that checking the checkbox is solved my issue.
        I´m happy now, but i will continue monitoring the topic

        Best regards
