      Hi there,

      I have a dedicated server at online with vmware.
      I have a pfsense (2.3-RELEASE) virtual machine wich act as a gateway between the internet and the "lan" which is in fact just another vswitch on wich all of my vms are connected.
      Evgerything works fine with ipv4.

      I'm trying to use ipv6 on theses machines.
      There's a doc on "online" website https://documentation.online.net/en/serveur-dedie/reseau/ipv6-prefix but it doesn't cover *BSD nor pfsense.

      I found this tutorial for FreeBSD http://barfooze.de/stuff/online_ipv6.txt but it doesn't work. I can't manage to get any ipv6 on the wan interface.

      I found this one for pfsense http://howto.arendtsen.dk/online-pfsense-ipv6/ but still no luck :(

      I don't really see what could I miss, the "DUID" part seems ok,  can see traffic coming so it's not a firewall issue, if anyone has an idea, i will be happy.

      Here's a log when I manually launch dhcp6c.

        One common issue when starting out with IPv6 is to block ICMP - IPv6 uses ICMP for RA and Neighbour Solicitation among other things, so if you do want to limit ICMP - be sure about what you are limiting and on what interfaces.

        Coming from the IPv4 world many people just turn it off and then stuff breaks;

        Give us some more idea of where your issues are and we'll try and help

          Hello,

          Actually, I restarted the computer, tried in "rescue mode" (the computer boot with a live cd ubuntu), managed to get ipv6 running and it worked.
          And when I restarted pfsense it worked too (i tried 2 or 3 times before to restart pfsense) so i suspect there was something weird witch the block that the rescue mode repaired.

            Hi!
            I am trying it as well, but my pfSense only gets a /128 as stated in the console. What did you do in rescue mode? I want to do it as quick as possible to have a low downtime…

            Regards
