      Hello,
      I'm trying to get an idea of what will be involved in upgrading a pfSense firewall (we are using version 1.2.3) so that it will be able to handle IPv6 in the future.

      I'm trying to test this by setting pfSense 2.0 up in VirtualBox on a PC with one NIC.  My LAN is bridged to the Microsoft Loopback Adapter. All of this was working until I downloaded the IPv6 code, at which point I lost internet connectivity and can't ping any IP address not set up on my own PC.

      Does the IPv6 code need some minimal configuration so that it won't interfere with the previously working configuration, and what would that be?

        Here is my experience

        Load pfSense 2.0
        Configure your LAN (or VLANs if you have any)
        Do not load ant packages yet
        Gitsync 2.1 (IPv6)
        Configure IPv6
        Test everything
        Now install the packages one by one.

          I don't have any packages loaded. Question - before you configure IPv6 does your firewall still function as it did before you gitsynced 2.1?  In other words, suppose I'm not ready to configure IPv6 yet, can I still get my firewall to work (pass data through as before)? Because what is happening to me is that after the gitsync of 2.1, my firewall blocks all traffic.

          Is there any way around that, that you know of?
          Thanks for your reply

            Yes you can gitsync to 2.1 and run just ipv4 if you want.  You don't have to do anything with ipv6 to have ipv4 work.

              IPv6 code will not break anything on the IPv4 front because it is a entirely seperate address family.

              That said, there have been moments during the development that broke one thing, the other, or the entire tree. Which is to be expected really. There are busy and quiet periods every now and then, the last month was quiet.

              Expect a flurry of activity soon though, hackathon is coming up which should bring up something.
