      That looks sane, what doesn't work if you're getting IPv6 ping responses? Capturing on WAN won't show any v6, it's v4 at that point, but you should see the outside of the tunnel as v4 to 68.114.165.1 from the looks of that. Capturing on wan_stf with tcpdump will show what's on the inside of the 6rd tunnel.

      I went back through my notes / log.  Seems that I can't read or was completely brain dead as I was not getting ping responses from 2607:f428:1::5353:1 and ipv6.google.com while ssh on the pfsense box.  So I reran it again and no ping response from both a ssh session and the web interface even when I try Charter's primary dns (2607:f428:1::5353:1).

        Ok, open one SSH session to the firewall, 8 to get a command prompt, and run:

        tcpdump -ni wan_stf

        Then start a ping from the firewall and what do you see there? Then a ping from a LAN host and what does it show?

            That all looks sane but nothing appears to go over the 6rd. Could we get access to your system? If so, please email me to arrange - cmb at pfsense dot org - with a link to this thread.

              Do you have wan_stf on your definition of WAN in rules.debug?

              Can you show the /tmp/rules.debug contents?

              UPDATE: Can you try with a snapshot from tomorrow and report?

                CMB has access to the box, but yes I'll try tomorrow's snapshot :)

                  After the Tue Mar 19 16:39:04 EDT 2013 build, I did have to go to the Interfaces menu for both the Wan and Lan and hit save and apply for the Ipv6 portion to update.  No changes were made to either interfaces.

                    What have you configured as your 6rd border ipv4 gateway?

                      Followed Charter's 6RD guide:

                      6RD Configuration Settings
                      As part of Charter's IPv6 Trials we have made available a Public 6rd Border Relay. If you are interested in participating in our early trials and own a device that supports 6RD use this configuration information to begin experiencing the Next Generation Internet:

                      6rd Prefix = 2602💯:/32
                          Border Relay Address = 68.114.165.1
                          6rd prefix length = 32
                          IPv4 mask length = 0

                      Primary DNS Address = 2607:f428:1::5353:1

                      Secondary DNS Address = 2607:f428:2::5353:1

                        Can you try issuing these commands until it works:
                        1- route add -inet6 default 2602💯44b8:yyyy::1
                        Check if it works
                        2 - ifconfig wan_stf inet6 2602💯44b8:yyyy:0::1/32
                        Check if it works
                        3 - route add -inet6 default  2602💯44b8:yyyy::68.114.165.1
                        Check if it works

                            Ah you should delete the default gateway before trying route add :)

                            or issue 'route change' instead of 'route add'

                                  I'm pretty sure the 6rd patch change on January 25 broke these. I just reverted those.

                                  edit: change backed out, don't upgrade to Saturday's snapshot if using 6rd.

                                    Don't upgrade if using 6rd at all for the moment. That change resulted in a kernel panic reboot loop when connecting to 6rd on Saturday's snapshot. I reverted things back to where they were a couple days ago. Sunday's snapshot should be fine, but probably want to wait to hear back from someone here.

                                      No Panic with the latest, but no IPv6.  I've run the tests prescribed earlier (manually setting routes) with no effect.

                                        Hi guys,

                                        Just tried the April 4th snapshot and it looks like 6RD is still broken.

                                        Is there anything I can do to help you get the information you need to resolve this? Log files, remote access? Just let me know what you need and I would be happy to provide it.

                                        -Will

                                          Ermal has access to a system on my network that's now broken and can work from that.

                                            It looks like it's still broken with the April 17th snapshot. I get a IP from my ISP tunnel, but i cant ping any other machine on the internet using ping6 through ssh.
