      I'm running 2.1-RC1 (i386) built on Sat Aug 24 11:30:48 EDT 2013. I have comcast. Their IPv6 is via DHCP6-PD.

      For whatever reason, my modem rebooted. In normal operation, the pfsense WAN gets a /128 with a 2001: prefix and the LAN get /64 2601: prefix. After this reboot event, both are gone and RADVD is gone from the services page. IPv6 will not automatically come back at this point without some user intervention.

      During the reboot, the modem acted as a DHCP (IPv4) server temporarily. It does this to provide connectivity to the modem's status/diag page. It gave pfsense an address of 192.168.100.10

      It doesn't seem to offer any IPv6 connectivity. It keeps a 30 second DHCP lease time so that when normal connectivity is restored, the router will attempt to renew and then get connectivity from Comcast's DHCP server.

      As an additional note, it looks like the reboot causes the link to go down. When normal connectivity is restored, the link remains up.

      I setup remote syslogging so I can provide any relevant logs from this event. I'm not sure what's relevant though.

      Here's RADVD's final words:

      Aug 27 14:24:50 cerberus.localdomain php: rc.linkup: Shutting down Router Advertisment daemon cleanly
Aug 27 14:24:50 cerberus.localdomain radvd[37768]: Exiting, sigterm or sigint received.
Aug 27 14:24:50 cerberus.localdomain radvd[37768]: sending stop adverts
Aug 27 14:24:50 cerberus.localdomain radvd[37768]: removing /var/run/radvd.pid

      To me it seems the steps to reproduce this are as follows:
      Create two networks. One with DHCP6-PD and one without any IPv6
      Have pfsense connect to the DHCP6-PD one
      Bring down the link and connect it to the one without IPv6
      Reestablish connectivity to the DHCP6-PD without affecting the link and remove the one without IPv6

        Yeah, I see the same thing; see here.

          Somehow the ticket for DHCPv6-PD issues was recently closed anyway: https://redmine.pfsense.org/issues/2919

            I guess a possible solution would be to renew (if it exists) or try and re-establish (if it doesn't) IPv6 connectivity any time the WAN IPv4 address changes?

              Well that's discouraging  :-. In any case, here's the output from the logfile. The lack of ability to reattempt IPv6 seems to be due to something in rc.linkup. It's what kills RADVD according to the logs.

                Ohhhhh, I see now.  I had made comments in the bug and forums that I am now retaining IPv6 addressing after a cable modem reboot.  Now I see the difference from my setup and what is being discussed here.

                My pfSense installation is running in an ESXi VM.  So, when the CM reboots, apinger declares the gateway down, but I don't see an actual interface link loss.

                It used to be that if the gateway was down, IPv6 addressing would be lost, radvd killed and never recover without a reboot.  That has been fixed.

                However, the link loss handled by rc.link up is apparently still broken.

                Hope that clarifies it for Ermal and team.

                  Unfortunately I'm not that familiar with PHP. I was looking around to try and figure out why this keeps happening (other than my modem is rebooting). The file services.inc has the string "Shutting down Router Advertisment daemon cleanly". It looks like the function services_radvd_configure gets some sort of config array for dhcpdv6. So long as there are greater than 0 elements in this new array it'll simply restart RADVD. Otherwise it shuts it down cleanly. Based on the logfile, it would seem that there should be 0 elements because the modem only provides the 192.168.100.0/24 subnet with no IPv6. Thus, it seems like it is correct in shutting down RADVD during this period.

                  However, when normal connectivity is restored, what is supposed to (re)start RADVD?

                    It is normal to get the radvd service shutdown when your ipv6 lease expires.
                    Normally when the modem hands over a temporary ipv4 lease it should handover even a v6 lease.

                    Not sure how you can build a reliable configuration process for v6 if the modem does not treat it as first class?

                      I don't think it would be normal for a modem to hand out a v6 lease in this case. Essentially it is disconnected from the cable company during this period. What v6 lease would it have to hand out? I strongly suspect all cable modems do this.

                      During bootup, pfsense assumes v6 is around and so initiates DHCP6 or whatever it's configured for*. The issue is when the WAN link goes down and pfsense is introduced to a v4-only network. Pfsense rightly turns off v6 stuff. But when the network changes again to a v4/v6 network, pfsense needs to assume that v6 might once again be available and go about it's usual v6 configuration setup. Or somehow detect that v6 is available again.

                      • I assume this is what pfsense does

                        As I had mentioned earlier, I think given the reality of how IPv6 is deployed to consumers through cable today, pfSense should not assume that IPv6 connectivity can only change at boot time and when the physical WAN link goes up/down (which I think is what it's doing now?); at the very least, it should assume that IPv6 connectivity can also (re-)appear anytime the IPv4 lease on the LAN expires.

                          I'm not aware of any DOCSIS 3.0 cable modem that would do this.

                            I put a fix and should be on new snapshots.
                            Test those out and it should fix what you are seeing.
                            Especially you should have get the v6 information from v4 setting ticket on.

                              Is this safe to do for a cable modem setup (IPv4 configuration type = DHCP, IPv6 configuration type = DHCP6)? What exactly does this option actually do anyway? The description is not particularly helpful in figuring out under which circumstances this setting should be enabled, and from reading the board I just have vague memories of it being somehow related to PPPoE (which I don't think is typically used with cable modems).

                                I wasn't sure what was meant for this so I tried the Interface -> WAN setting that says

                                Request a IPv6 prefix/information through the IPv4 connectivity link

                                This completely prevented pfsense from getting IPv6 connectivity.

                                The fix didn't seem to work as power cycling the modem still caused a loss of IPv6 connectivity until some user intervention occurred.

                                The version is 2.1-RC2 (i386) built on Thu Sep 5 09:59:12 EDT 2013.

                                  Since it will restart ipv6 anytime you get a new ipv4.

                                        The system is an Alix 2D3 board. I only use the WAN and LAN. DHCP and DHCP6-PD on the WAN. Direct connection between the modem and pfsense's WAN. No packages except the openvpn client export.

                                        The log looks quite similar to the one I posted previously. I filtered out  "pf:|ntp|openvpn|dhcpd|dnsmasq|arpresolve:" so if you want the logs that include those terms, let me know.

                                          Can you sync to 2.1-RELEASE code and retry and also re-post the system log?

                                          I need to see an event fired that is not logged at the moment.

                                            Did a gitsync with pfSsh.php playback gitsync RELENG_2_1
                                            Rebooted system.
                                            Unplugged power to modem. Plugged it back in. IPv6 did not return.

                                            Here's the system log. This time I only filtered out "pf:|ntpd|openvpn"
