      6rd isn't broken in general. I use it for my production v6 at home, upgrade at least once a week, and it's worked on every version since I first enabled it several months ago. I'm posting this via 6rd on a snapshot from within the past few days. Going to need more than "it's broken" since that's not true.

      What does ifconfig look like? What does your v6 routing table on the firewall look like? Host's IPv6 config and routing table? Packet captures on WAN, wan_stf, LAN?

        My apologies, Charter's 6RD implementation doesn't seem to be working with the current snapshot of pfsense 2.1 last known working snapshot was the Jan 22nd snapshot

        Info on Charter's 6RD:

        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

        Version: 2.1-BETA1 (amd64) built on Sun Mar 3 10:04:04 EST 2013

        How I setup 6RD:

        Followed the above instructions for WAN interface

        IPv6 Configuration Type : 6rd Tunnel
        6RD prefix : 2602💯:/32
        6RD Border Relay : 68.114.165.1
        6RD IPv4 Prefix length : 0 bits

        For the LAN interface:
        IPv6 Configuration Type : Track interface
        IPv6 Interface : WAN
        IPv6 Prefix ID : blank

        Packet Capture is showing nothing for WAN interface IPv6 address family
        even though I was getting ping responses from 2607:f428:1::5353:1 and ipv6.google.com directly on the pfsense box.

          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.
