      Thanks for filing that bug. Hopefully it gets some attention soon. I think you are right about a bug in the code. I just upgraded to 21.02-RELEASE for my SG-1100. It states for WAN_DHCP6 unknown for status. Yet the following is true.

      • Under interfaces it lists the IPV6 address for WAN
      • I can ping ipv6.google.com with IP protocol IPV6 from Diagnostics -> Ping

        Someone else filed it. I only shared it here in the forums.

        Under interfaces it lists the IPV6 address for WAN
        I can ping ipv6.google.com with IP protocol IPV6 from Diagnostics -> Ping

        Take note that in 2.4.5-p1 under Status | Interfaces there is a field for Gateway IPv6. This is completely missing for pfSense+ 21.02 and pfSense CE 2.5

          I have the same problem after update to 2.5.0

          IPv6 is working but there is no gateway.

            pfSense has the IPv6 gateway but is not showing it under Interfaces tab and widget.

            After I reboot the cable modem I again getting IP addresses but then no IPv6 connection. Pinging also isn't possible anymore. Tried everything only rebooting pfSense works.

            BUT: my second WAN (PPPoE DSL) is working without any issues. It's only the cable connection. Both connections use the same IPv6 config to get the /56 prefix (that seems working) and the PPPoe also is getting IPv6 Gateway. The cable does not.

                  This worked for me. Now passes on all IPv6 test sites I tried.

                    As suggested, manually adding the Monitor address seems to solve part of the issue, though with Gateway hardcoded as "dynamic", it seems to affect the ability to use it in firewall rules -- CoDel Limiters, for example below.

                    21:00:51 There were error(s) loading the rules: /tmp/rules.debug:223: no routing address with matching address family found. - The line in question reads [223]: pass  out  quick  on {  igb1  }  $GWWAN_DHCP6 inet6 from any to any tracker 1610764779 keep state  dnqueue( 2,1)  label "USER_RULE: CoDel Limiters"

                        @amessinamessinet-com This is the problem I'm having as well. I set the monitor address to the link-local address but now my CoDel Limiter for IPv6 is giving that error.

                          Yep... See this bug: https://redmine.pfsense.org/issues/11454

                          As you mentioned, only part of the issue has a workaround (the monitoring, which affects IPv6 connectivity as a whole). The gateway selection part will likely require an update to pfSense once fixed.

                              Still no ETA for a fix? IPv6 is unusable after WAN fails one time.

                                I can ping ipv6.google.com with IP protocol IPV6 from Diagnostics -> Ping

                                That's where I am on an SG-2100 with 21.02, I can ping that from my PC behind it. Status/Interfaces has a default route for IPv6. The router has a default route for IPv6 in Diagnostics/Routes, just no gateway for IPv6 shown in Status/Interfaces.

                                It sounds like some people have IPv6 connectivity and some don't? Essentially for me it's just a cosmetic issue with the GUI. After upgrade I (re)installed pfBlockerNG-devel and Snort but didn't reboot again.

                                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.

                                  I noticed that both /tmp/em0_routerv6 and /tmp/em0_defaultgwv6 were empty while the ipv4 versions had the valid router addresses in them. Both of these are set in the script /var/etc/rtsold_em0_script.sh which is built by the script /etc/inc/interfaces.inc. It looks like the parameter is not being passed to the script. I modified the routine in interfaces.inc that builds the resold_em0_script (search for "rtsoldscript") to set a hard coded value for both these files and my IPv6 gateway started working! Routing, firewall rules, Policy Based Routing, etc, all work!

                                  My mods:

                                  #echo $2 > /tmp/em0_routerv6
                                  echo "fe80::X:X:X:X" > /tmp/em0_routerv6
                                  #echo $2 > /tmp/em0_defaultgwv6
                                  echo "fe80::X:X:X:X" > /tmp/em0_defaultgwv6

                                  After I made the mods, I "saved" the WAN interface again without making any changes. Hope this helps someone until a real fix is pushed out.

                                          I'm also seeing this issue.

                                          @g-shaffer What are you setting as the "hard coded value"? The Link Local IPv6 address of the WAN?

                                            @randyshoopman I got it by looking for the "receive advertise from ..." in the dhcpd.log, but you should be able to use the default IPv6 route address (minus the %interface) listed in the default route table (Diagnostics -> Routes).
