Can't get Dual Stack *quite* running



  • Well I got the issue sorted of my LAN receiving IPV6 Addresses, my WAN connection got its /64 allocation from the ISP

    I have the gateway up, but for some strange reason, when I go to http://test-ipv6.com , it still tells me that ipv6 is not enabled

    I've created the rules as well to allow ipv6 traffic out, but for some strange reason I cant get it to work

    Anyone got any ideas please for what I am missing?



  • Well, there is a lot of missing info. Like, are you routing from one range to another?
    What happens when you trace route to 2001:4860:4860::8888 from the firewall and from a system behind the firewall?

    Details on you setup will only help here.



  • Routing only from the internal /56 the ISP supplied me (2001:44b8:22b:b100)

    I've got it successfully showing up as assigning addresses out via DHCP

    Here's what happens when I try to tracert the afore mentioned address

    Tracing route to google-public-dns-a.google.com [2001:4860:4860::8888]
    over a maximum of 30 hops:

    1  Destination host unreachable.

    Trace complete.

    I have the Firewall rules set to allow traffic, LAN auto added them when I did a factory reset

    I also added one via WAN to allow, should I set it to allow all ipv6 data from lan?

    Let me know what other info you need

    EDIT: Attached shows that the necessary ipv6 addresses are there












  • What is intresting is that fe80 addresses are not internet routable.

    from  http://en.wikipedia.org/wiki/Link-local_address :

    Link-local addresses for IPv4 are defined in the address block 169.254.0.0/16. In IPv6, they are assigned with the fe80::/64 prefix.

    If they are routing that block to you, it is not going to be on that gateway. Perhaps they are expecting you to route on another IP? I would think that the gateway is somehow wrong since any router will not pass a link local address.

    Your WAN is assigned an address from dhcp, so you are probably going to have to talk to your ISP. All the ones I have dealt with so far all use static IP and not from a dhcp, so I might be wrong.



  • Your gateway can be a link local address. There is no harm in specifiying the gateway as a link local or global address since it is the same host.

    It makes perfect sense for gateways since these are normally always directly connected.

    thanks for the clarification.



  • Turns out there is a device or two on the network here that wont work with ipv6, so I've had to turn off the ipv6 stuff for now :(

    Mainly the FetchTV box and the printer, the moment both IPV4 & IPV6 are being advertised, those 2 devices stop working

    All good, without ipv6 running now, the network is running rather nicely

    Im rather liking the uptime :D
