Hello,

Can someone who has this working post what settings they're using? I tried using IPv6 using a Draytek Vigor 130 over Snap VDSL.

The settings I'm using on the DV130 are:

"Connection Type: DHCPv6 Client";
"Identity Association: Prefix Delegation";
"IAID (Internet Association ID: <this field always seems to have a random number in here>"

The page looks like this: http://iforce.co.nz/i/qq2xx0ka.b23.png

I can't get it to pickup a IPv6 addres from Snap.

My end goal is to get this working with pfSense but for now I'll be happy if I can just get it working right on the Modme itself.

DHCPv6 is the wrong connection type

Snap VDSL connection type is: PPPoE, VPI/VCI: 0//110, VLAN: 10 as per:
http://www.snap.net.nz/support/content/1/17/en/general-settings.html

Your modem gets assigned ipv4 and ipv6 addresses from Snap's systems after/as part of the PPPoE connection.

Hi Ragnor, I appreciate the reply.

The reason I was trying DHCPv6 with PD was because of some other posts here (specifically this one)

I have just tried it with PPP mode as you said, and it doesn't work. I've also e-mail snap who told me the DV130 is an 'unspported device' and that I was SoL.

The guy in the thread I have linked has it working, but he's using an Asus RT66N with Tomato fimware.

Any insights on how to get this going would be appreciated.

Hmm that makes sense, so you need both the PPPoE connection for ipv4 and the DHCPv6 connection for ipv6 on Snap...

Someone must have a DV 130 on Snap or WxC with working ipv6.

The Vigor's arn't compatable with Snap IPv6, they pick up addresses but refuse to route.

I can't even get mine to pick up an address. I've also got a pfSense here that isn't having much luck either.

SnapperNet (no relation to Snap) are the main NZ distributor of Draytek maybe contact their support and see if they can help or advise if the DV130 will work on Snap VDSL2 w/ IPV6

I never got my Vigor to pick up IPv6 directly from Snap!

I was eventually able to get OpenWRT to negotiate a IPv6 prefix over PPPoE, when IPv4 connects, however, it's not the most reliable. I suspect it's to do with Snap!'s implementation of IPv6 (Read: useless)

It still makes no sense to me why they won't provide static IPv6 prefixes, either. What's up with that?!

Long story short though; you may get IPv6 working in some form on Snap!, but it won't be very reliable.

Right.. might give it a miss for now then.

Aaroona, just out of curiosity can you post the steps & settings you used to get your router to pickup IPv6? And when you say it was unreliable exactly what do you mean?

Thanks.

This ild be interested in too.

is it simply that your getting a new v6 ip often?

To be honest, my issues could have been resolved by having a static IPv6 prefix.

I got round most of my issues by ensuring my DHCPv6 forced Stateful addresses only.
the IPv6 issues I have are not caused solely by the implementation that Snap! has, but it certainly hasn't helped either.
I.e. if PPP drops, for whatever reason and you have a Stateless assigned IP, when the internet comes back on, you for some reason still have your old stateless IP with the previous IPv6 prefix and IPv6 stops working, sometimes stopping internet traffic to IPv6 sites all together.

I noticed this issue across Mac and Windows, though iOS seemed to be unaffected.

I just wish Snap! would implement a seemingly normal implementation of IPv6 instead of what they have now.

... and give us static Ipv6 prefixes, so I could open ports happily, without having to use the security hole that UPnP is.

There are actually no steps to provide...
OpenWRT provides a native IPv6 stack, whereas previous versions didn't.

All I did was put my Vigor 130 into bridge mode, setup a PPPoE connection from OpenWRT to the modem, and off she went. (Negotiates the Ipv6 over the PPP connection, when IPv4 starts)
IPv6 was enabled by default, so no configuration was required. As long as your OS supports IPv6 you should be good to go.
One of the things I did notice though, was that because of Snap's implementation, you'll find the IPv6 (wan6) interface in OpenWRT doesn't actually get an IPv6 address assigned to it. It gets assigned to the LAN (br-lan) interface, then assigns out from there. Again, it works, but it's by no means a great setup.

I've recently disabled IPv6 completely, as it was causing grief (different issue)
