      @Gertjan I don't have dual wan and track interface is the default in pfSense. What is wrong with that?

      "Change DHCPv6 display lease time from UTC to local time" didn't help.

        @Gertjan I appreciate your help but you have a total different setup with that he-tunnel and probably not having dualstack on your wan.

          When I do a "route print" in the windows vm, there is a difference between full connectivity and problematic connectivity. The following (first) line is missing after some time.

          IPv6 Route Table
          Active Routes:
          If Metric Network Destination Gateway
          9 271 ::/0 fe80::215:5dff:fe01:7507

          This is the PrivatSwitch Interface.

            I found this in the logs:
            route 0::/0 lifetime (60) conflicts with AdvDefaultLifetime (0), default routes will flap!

            So I guess it is a problem with radvd. Ubuntu has no problem with that but windows does. I remember when I was adding the second LAN-Interface called Privat Switch, it was missing the defaults at least under Router Advertisements completely. I also switched the interfaces once, which one should get IPv6 and which one not. So something is broken there.

            Is there a way in pfSense to bring the defaults to that setting?

              @Bob-Dig said in IPv6 Connectivity problem in vm:

              I have 2 computers with Windows 10 in VirtualBox on Linux. Neither have a problem with radvd. You can run Wireshark in Windows and watch for ICMP6 to see what's happening.

              I haven't lost my mind. It's around here...somewhere...

                @JKnott Thanks. But I guess you don't have those problems under
                Status - System Logs - SystemRouting like I have, log was flooded with:

                route 0::/0 lifetime (60) conflicts with AdvDefaultLifetime (0), default routes will flap!
                

                So after I changed the Router lifetime to 1000s in ServicesDHCPv6 Server & RA PRIVATSWITCHRouter Advertisements
                Later I get those log entries flooding:

                Mar 13 08:58:28 	radvd 	81932 	version 2.18 started
                Mar 13 08:58:29 	radvd 	82558 	attempting to reread config file
                Mar 13 08:58:29 	radvd 	82558 	resuming normal operation
                Mar 13 08:58:31 	radvd 	82558 	attempting to reread config file
                Mar 13 08:58:31 	radvd 	82558 	resuming normal operation
                Mar 13 08:58:45 	radvd 	82558 	attempting to reread config file
                Mar 13 08:58:45 	radvd 	82558 	resuming normal operation 
                

                Also I am using the 2.5.0-DEVELOPMENT Branch

                So is it possible to reset the DHCPv6 Server & RA, because there seems to be the problem.

                  Dono if this is related : https://redmine.pfsense.org/projects/pfsense/issues?per_page=100&query_id=104, look for the 'radv' occurrences on the list.

                  @JKnott : you're using 2.5.0 - and if so, what version ?

                  No "help me" PM's please. Use the forum, the community will thank you.
                  Edit : and where are the logs ??

                    @Gertjan 2.5.0 get updates three times a day and I am remembering the problem with no defaults for the DHCPv6 Server & RA was only when I was adding the second LAN-Interface later on. So probably no one noticed it.

                    If I can't reset it, I will have to go back to 2.4.* and do everything manually. ☹

                      There is no reset button.

                      But what you can do, is saving your config, and then reset to default the entire setup.
                      When done, take a look at the config xml file, look for 'radv', and compare and copy if needed that part into your config.xml.

                      This a a part of the config, related to 'radv' :

                      6a349553-8855-4a0a-86ba-25c957d4c2d7-image.png

                      You'll find two blocks of these, as you have two LAN type interfaces.

                      When you edited (if needed), you import back in your config file.

                        What I finally did was deleting the interface and then creating it new. This time there seems to be no problem.

                        Thanks everybody.

                        I have to read more log files to get a sense, when there is something not ok.

                        Also I crafted some new IPv6 addresses in the DHCPv6 Server, like this one:
                        ::192:168:2:37

                        😋
