Billion 7800N: Not Working!

[#1]

Also, do the computers on your network have an IPv6 Default Gateway and DNS addresses? Those settings on my PC are blank.

[#2]

Both primary and secondary are blank.
I have a static IPv6 set up on one PC which will work without the manual work around but dynamic on another which will only work after applying the fix.

Can you tell me how to setup a static IPv6 address?

[#4]

I'm really not an expert, but I don't think you need to worry about setting up static IPv6 IP's on your computer. It looks to me like your router's not picking up an IPv6 block from our RADIUS server which is likely to be down to a config issue within the router itself. I asked for the first 4 digits of your IPv6 address earlier to make sure that your computer is set up for it (it is) and to check if you were getting an internal or external address (it's internal).

[#5]

Oh ok. I am not an expert either! IPv6 is totally new to me. I have knowledge on IPv4 though. PeteB, do you get an IPv6 address on the router status page?

[#6]

Yes I do get an IPv6 address on the router status page.
I agree that a static IPv6 setup should not be necessary. The only reason I set one up was to try and fault find the unresolved problem I have with IPv6, the 7800N and Plusnet.

Hmm, that's my problem. I have no idea what could be causing it though?

[#8]

The 7800 setup notes I have sent you via PM have a very short section on changes required to enable IPv6. It is very short because there is very little to do.

I have sent the TeamViewer login details.

Invalid Teamviewer password.
IPv6 setup section in my notes.
Configuration -> WAN -> WAN Profile
IPv6 Enable

Click on Save Config, Apply
Click on Restart

Thanks to PeteB (thank you!) I have got IPv6 setup. Annoyingly, you have to run a code to make it work every time the internet disconnects. Annoying, but hey, at least IPv6 works.

[#12]

If you set up a static IPv6 address you do not have to apply the manual fix, but it is not an ideal solution.
On Windows 7 I had to set the IPv6 address and a Preferred DNS server.

[#13]

How do I set a static IP?

[#14]

Setting it is much the same as setting an IPv4 address.
The most difficult (not very) part is working out what it should be.
Edit: I used the IPv6 prefix allocated to the router by the Plusnet RADIUS server and added the MAC address of the network adapter to the end.

Hi Pete,

Whilst there's nothing intrinsicly wrong with that approach, if you are going to statically allocate an address you might as well take advantage of the situation and define a short/intuitive address.
e.g. If your prefix was 2a02:16c8:2000:600::/48 then, say, for your Dell 1545 laptop you could assign it 2a02:16c8:2000:600::1545.
Such an address can therefore become more meaningful and a bit easier to handle and/or identify.
Incidentally, just for info, the process of basing the host portion on your MAC address usually involves padding out the 48 bits of the MAC address and flipping a bit (section 4 of RFC2464 refers).
