      Ever since upgrading to pfSense 2.7.2 CE from 2.6.0 CE, the WAN interface will lose connectivity until pfSense is rebooted. My fiber modem never goes offline and there have been no outages with my ISP. No hardware changes have taken place with the firewall. It is not virtualized.

      Looking at the logs, I saw this before I rebooted the firewall:

      Feb 22 08:01:31 	rc.gateway_alarm 	54098 	>>> Gateway alarm: WAN_DHCP (Addr:x.x.x.x Alarm:1 RTT:1.046ms RTTsd:.259ms Loss:21%)

Feb 22 08:01:32 	php-fpm 	70525 	/rc.openvpn: OpenVPN: One or more OpenVPN tunnel endpoints may have changed IP addresses. Reloading endpoints that may use WAN_DHCP.
Feb 22 08:01:32 	php-fpm 	26777 	/rc.filter_configure_sync: GW States: One or more gateways is down, flushing all states: WAN_DHCP

      I have adjusted the WAN monitoring setting in System / Advanced / Miscellaneous > State Killing on Gateway Failure to Do not kill states on gateway failure to see if this helps based on other forum posts.

      If anyone has any insights on why this his happening or is a known bug with 2.7.2, would appreciate a reply. Thank you.

        Is there anything logged before that?

        By the time you see a gateway alarm like that whatever is causing it has already happened.

          Rebooted Here.

          After doing some more reading, I came up with that it might be pfBlockerNG under Firewall / pfBlockerNG / IP > Kill States which is currently enabled or possibly setting System / Routing / Gateways / WAN / Edit and turn on Disable Gateway Monitoring, or set a more reliable Monitor IP such as 1.1.1.1.

            Mmm, nothing much there. pfBlocker didn't do anything at that point because there were no changes.

            But setting an external ping target for monitoring is a good idea anyway.

              Thanks for the reply. Any thoughts on turning on Disable Gateway Monitoring or would you suggest targeting a stable monitoring IP first and then moving on to Disable Gateway Monitoring if it persists?

              For additional context, this is a simple home setup, single ISP, and not something that requires intensive WAN monitoring and state killing to switch to a backup connection.

              pfBlocker seemed an unlikely candidate to me as it wouldn't cause 21% packet loss 1.5 min later, it'd cause 100% if something got blocked.

              Final question is if anything was changed between CE 2.6.0 and 2.7.2 with regards to the System / Routing / WAN settings that introduced more aggressive interface monitoring?

              Thanks again in advance for any further insights.

                @xSirrus FreeBSD version therefore maybe drivers. What NIC hardware is WAN?

                Did you try a different patch cable?

                Turning off monitoring will leave it up with the observed packet loss. Doesn’t fix the packet loss of course.

                Pre-2.7.2/23.09: 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 restart, or more depending on packages and device speed.

                  Hi @SteveITS

                  It is connected to the onboard NIC which is either an Intel i210 or i211. LAN connectivity is via a 4 port Dell branded Intel i350 based NIC. In either case, both are supported in FreeBSD 14. Since the packet loss is not consistent and rebooting the firewall corrects the issue every time, cabling would appear to be a less likely source of the issue. Thanks for suggesting it as a point of investigation regardless.

                  Yes, I realize turning of monitoring would indeed not solve packet loss, especially if it the result of a faulty cable, faulty modem from the ISP causing the packet loss, or somewhere further upstream on the ISP side. The issue as it stands is that when the packet loss occurs, even if it's 21% loss as shown in the log, with the settings the way they are/were, the states get killed and the WAN connection never recovers until pfSense is rebooted.

                  The timing is also suspect in that I had no stability issues on 2.6.0 and start encountering issues right after upgrading to 2.7.2.

                    Yeah if you only one WAN I would disable the monitoring action but leave monitoring enabled. It's useful to have a record of the WAN status for troubleshooting issues.

                      Thanks for the replies and insights. So far it's been over 24 hours with no issues. I'll report back after a longer period of time if issue re-occurs with details.
