      @ermal:

      Have you tried under system tunables to change the prefer.old_ipsec_sa set it to 1 from 0.
      That might help stability.

      No, but I have the "System: Advanced: Miscellaneous"
      "IP Security -> Security Associations"
      Prefer older IPsec SAs = TRUE (ticked)

        Show the output of:

        setkey -D
        setkey -DP

        And /var/etc/racoon.conf

        I think someone else recently saw this and it turned out to be from the way that we wrote out or compressed/decompressed the IPv6 IP when comparing them. They didn't match exactly because of how it was written on one side or the other.

          jimp:  Could you mail me off-list where to send the printouts as I don't want to publish that data in the forum.

              I sent a PM asking for more info.

              The indicator works for me on current snapshots in the widget and the status page, when I send some traffic the tunnel goes up and I see it turn green on the widget and the status page.

              The connect button is definitely broken, I opened a ticket for that.

                As you could see in the screenshots it's not just the overview page that shows down/error.
                Also the Widget shows the IPSec on the opt1 interface as red=down.

                So it seems like something is broken and as you said, it could be rare cases with special
                structure in IPv6 address that is causing it.  However, the IP assigned to me is real and
                official so it is nothing wrong with the addresses.  They are assigned by Tunnelbroker.net.

                The mystery thickens… :-)

                I have sent you a reply via PM.

                  A commit just went in to fix the connect button for IPv6, so that should work on snaps from later today/tomorrow on.

                  Still not sure why your tunnel doesn't show as 'up' though. And you say it is actually passing traffic? (You can ping back and forth inside the tunnel)

                    Jepp,  tunnel is working ok and i could see that the bytes is increasing on the SAD screen.

                    Have tried to ping devices on both ends through the ipsec through the tunnel.

                        I figured it out, it's the local phase 2 being set to "lan" that does it. The status code made an incorrect assumption about what data it had access to, fix will come later today when I get time.

                          Good.

                          It should  be able to handle this as:
                          Address
                          Network
                          WAN subnet
                          LAN subnet
                          <optx_interface_named_to_whatever>subnet
                          None

                          And also possible the NAT/BINAT entries…

                            Yeah the other parts worked just not the interface macros.
                            Just checked in a fix, should be in snaps late today/tomorrow.

                              I will test it and get back with results.

                              Checked you checkins in the github activity page.  :-)

                              Thanks for the fixing…

                                Have tested the "Thu Feb 7 07:21:31 EST 2013" release but can't see the "Connect button" fix (still shows src=192.168…)
                                and also I have even more problems with the IPv6 tunnels.  Now they are not even coming up. :-/

                                And saw the following in the RACOON Debug log.  (have have altered some IPv6 address to protect me.  (xxx= remote yyy=local)

                                  Edit your phase 2's and make sure the ipv4 and ipv6 ones have the correct tunnel mode selected (tunnel or tunnel6).

                                  Ermal checked in a fix for a typo I made so it's also possible that caused the issue as well, but I don't recall if the code there was used in that particular path or not.

                                    I just checked an unmodified setting of the IPv6 tunnel and both phase1 proto = IPv6 and phase2 = TunnelIPv6 and Local = LAN Subnet, Remote = Network + IPv6 address /64
                                    but still got the problem shown above in previous mail.

                                    UPDATE: Have now tested "built on Fri Feb 8 05:38:00 EST 2013" but the Connect button is still

                                    And also I am now still not able to get the IPSec v6 again.   It is broken.  It broke in any of the latest builds.

                                    Still seeing these kinds of problems:

                                    I have tested to toggle the value in the setting to get it to work but same result.

                                    I have also tried to wipe the whole IPSec_v6 tunnel incl. phase1 and 2 and completly rebuilt from scratch but same result.

                                      Can you send me your ipsec part of config xml including interface config?
                                      Through PM or email whichever you prefer.
