[quote="billion_fan"]On the WAN side delete the '::' and enter xxxx:xxxx:feed:6069::/56, then you should have a fixed IP. You will also need to enter a static IPv4 address on the WAN section for the unit to accept your Ipv6 configuration.
Trying to revisit this....
Billion_fan, could you please try and explain this? Surely a static IP address in IPv6 should be represented (in your example) by xxxx:xxxx:feed:6069::/128?
Where on the WAN profile should the static IPv4 address be entered?
I currently have IPv6 working just fine on my config by having the '::' entered on the WAN profile page and a /64 subnet entered on my LAN->IPv6 autoconfig page. The main status screen reports my IPv4 static address and an IPv6 address which changes on router reboot. All networked devices report 10/10 on IPv6 test pages on the internet.
What do I need to change in my config to get the 7800n to retain a fixed IPv6 address -based on the LAN MAC and the /64 prefix supplied by my ISP - on reboot?
Advice, please!
Jon

Re: Strange ipv6 behaviour
The tests I have performed to get static a IPv6 address is to enter my IPv6 address in the section provided (WAN section) also I need to enter my static Ipv4 address (as we have both static addresses)
This is provided by your ISP, like our ISP ENTA have provided to us.
So for example they provided us with 2001:4d48:ad52:1700::/64, we set this to LAN auto config, on the WAN side we set 2001:4d48:ad52:1700::/56, as advised by our ISP.
Then save and reboot the router, once rebooted we have our IPv6 static address listed below our static IPv4 address. (found on the status page)
A quick test using http://test-ipv6.com/ confirms everything is working fine.
If the only way you can get Ipv6 working is to enable :: (meaning auto settings) and your IPv6 address keeps changing it seems like your ISP are assigning dynmaic IPv6 addresses. (I could be worng as there is no industry standard for IPv6 yet, BT are still testing IPv6 with us but other ISP's seems to be working fine)
