IPv6 on WAN

xeonic
Recently my ISP started to support IPv6 natively, they are handing out a /56 subnet via DHCPv6. My ISP provided router is currently working with IPv6 but I can't seem to get my UTM to grab an IPv6 address. 

I enabled IPv6 in 'Interfaces & Routing' and I have my WAN interface (eth0) set to both IPv4 and IPv6 default GW plus dynamic IP. 

Is there anything else I need to do?

I noticed that in the 'system messages' log, there are only entries for WAN IPv4 DHCP requests, there is nothing related to IPv6.

Thanks!

    As far as I read and testet the IPv6 implementation on UTM is really buggy regarding prefix delegation from ISPs (see several thread from user "Ben" and others).

    So if any of you has a paid license please open a support case with Sophos...

    just a bit buggy ya ;) 

    it sometimes help to deactivate/reactivate IPv6, do delete the prefixes via shell and restart the watchdog (scorpionking posted that on the old astaro.org board) ->

    rm /var/chroot-dhcpc/var/db/*.leases6
    /var/mdw/scripts/ipv6_watchdog restart

    If anyone wants i can have a look via teamviewer/anydesk, i am really interested how other ISPs handle it. Just send a PM with Skype or other IM Contact.

    IPv6 works fine on my UTM (9.3)

    1. enable IPv6 under interfaces >ipv6 >global and it should show under the global tab.
    2. enable the prefixes under the prefix advertisements for the interfaces you want IPv6 to use. This is where you decide if you are going to use Router advertisements, the dhcp server on the UTM or a windows DHCP server etc
    3. enter the IPv6 gateway address for each interface

    It should work then. I have multiple vlans running IPv6 sucessfully on UTM9.3. One thing to remember is that you can't have a static IPv4 and IPv6 running at the same time. Simply change the IPv4 to dynamic and your IPv6 will connect. You can still use static IPv4 addresses as I do but no not set the inferface as static.
