Charter 6RD connection not working in latest snaps



  • Hi guys,

    I use Charter's 6RD service to get ipv6 connectivity. I'm currently running the Jan 18th snapshot and my ipv6 connectivity is working fine. I usually update my pfsense version about once a week so when I updated near the end of January the 6RD connection didin't work so I rolled back the snapshot (running pfsense in an ESXi VM) and the 6RD connection started working again.

    I just updated to the today's (Feb 27th) snapshot and it's still not working. It appears that I get an address from Charter on the WAN interface…I can see it listed in the console and in the GUI but my monitored gateway in the dashboard shows off-line and connectivity tests to test-ipv6.com and to ipv6.google.com both show ipv6 isn't working.

    Any idea what might have changed in pfsense to cause this?

    -Will



  • Mine hasn't been working since early January either. I'll test new builds occasionally to see if it has been fixed but need a reliable connection so I've disabled IPv6 completely.



  • updated to March 1st March 3rd, and still no luck.  Did anyone save the Jan 18 snapshot?



  • I have the x86 build from the 22nd in which 6rd still worked.



  • Hi guys,

    I wonder if this change:

    http://redmine.pfsense.org/projects/pfsense/repository/revisions/a6bc492fecd64a3a9f3b4cc4a003d6761494a694

    has anything to do with the problems we all seem to be having.

    Might have to edit that file and see.

    -Will



  • Hi guys,

    Well editing the file as suggested in the previous port did not seem to work.

    -Will



  • Not sure if  the Jan 23 snapshot worked or not, but this seems to be close to where 6rd started breaking.



  • 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?



  • Starting from the beginning to make sure nothing has changed.

  • 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?



  • @ermal:

    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



  • Didn't have much luck, none of those worked.

    route add -inet6 default 2602💯44b8:yyyy::1
    route: writing to routing socket: File exists
    add net default: gateway 2602💯44b8:yyyy::1: route already in table

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

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



  • Same result

    route change -inet6 default 2602💯44b8:yyyy::1
    change net default: gateway 2602💯44b8:yyyy::1

    ping6 2607:f428:1::5353:1

  • Can you give me access to the system as well its easier that way.



  • 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.



  • I have the same issue with 6RD tunnel on Rogers.



  • Still not working with charter 6rd as of the May 10th build. Any updates on this?



  • Hi ddggttff3,

    The ticket I opened back on 3\15 was accepted, but hasn't been touched since. The only thing I've heard (via another post) is that they have a box that exhibits the same issue at the shop & they can work on it in-house, so there's no need for remote access to a customer machine.

    -Will



  • Anyone know where I can find the January 27th snapshot to revert so I can test the 6RD with it? I'm running it with Centrylink/Quest.



  • @maxinfo:

    Anyone know where I can find the January 27th snapshot to revert so I can test the 6RD with it? I'm running it with Centrylink/Quest.

    I have the Jan 22 x86 build if you want it. 6RD was working with it. If I remember right, it broke with the 1/24/13 build.



  • Yea I'd love to give it a shot. Can you PM me a dropbox link or something similar?

    Thanks much



  • Hi guys,

    Sure do wish they could figure out what changed with that build & sort this out. I'd love to see how much better 2.1 is after 5 months!

    -Will



  • Thanks Swinn. The Jan 22 build is working well. The Centurylink gateway doesn't respond to ping but I can route and just changed the monitor IP by 2 hops down. Hopefully the 6rd problem will get worked out eventually but running beta software I expect things like this.

    Thanks again for the help.



  • Should work with tomorrow's snapshot, my test system is fixed now.
