Can't route IPv6

  • I'm pretty new to pfsense. I have one machine up and running at home just fine with IPv4 and IPv6, no problem. It's at work that I'm running into some hassles.

    Our ISP gave us a /48 that is routed to our gateway. They (ISP) also set up a /126 on the WAN side of things. Currently it looks like this:

    2607:xxxx:2::/48 is what they gave us.

    2607:xxxx:1::5  ISP gateway

    2607:xxxx:1::6  Existing FreeBSD router, full IPv6 connectivity behind it, hands out addresses from a /64, everything works fine. Hands out addresses from 2607:xxxx:2:1::1/64

    2607:xxxx:1::7  Another FreeBSD box I'm just playing around with, everything works fine on the IPv6 side behind it as well. Hands out addresses from 2607:xxxx:2:2::1/64

    2607:xxxx:1::4  pfsense box I can't quite get to work right. Hands out addresses from 2607:xxxx:2:3::1/64

    Th pfsense machine will hand out IPv6 addresses just fine from the proper pool. Internally I can ping 2607:xxxx:1::4 (the pfsense box) just fine but NOTHING else. Can't ping any of the other /126 addresses.

    The pfsense box itself can ping anything I ask it to in the IPv6 world.

    So - pfsense is handing out appropriate addresses, but those addresses cannot reach "the world." They can only reach the WAN side of the pfsense box.

    Any idea what I'm missing?

    That doesn't make a lot of sense.


    2607:xxxx:1::4 - 2607:xxxx:1::7

    But upstream is routing the /48 to one of those. I don't know how you have two nodes with 2607:xxxx:1::/126 addresses on them with 2607:xxxx:2::/48 behind them.

  • D'oh! I bet you're right. My stupid mistake!
