Also check how your firewall handles ICMP traffic. As if it blocks all ICMP, you will probably get MTU problems. As the ”packet too large” replies will get blocked.

Fritz!Box gets its AAAA info (for fritz.box subdomains) from mDNS.

DNS requests time out to fritz.box subdomains with 14+ AAAA records, likely due to the response exceeding 512 bytes.

I've caused this by having Avahi register new AAAA records without withdrawing the previous AAAA records, resulting in lingering IPv6 addresses. (The lingering addresses are generally temporary privacy addresses, which are not used after a device reboot)

These timeouts only occur on the 14+ AAAA record fritz.box subdomains, not to queries to to other fritz.box subdomains or for queries to domains on the internet.

Using Fritz!Box 7490, ver 07.01, only tested SLAAC (haven't tested DHCPv6 IA_NA)

Will there be an example for ipv6 for use with unifi?

Wondering if this would solve my open port issues since unexpectedly finding out in now behind a cgnat and all my webservices no longer work.

dynamic ipv6 address would be fine as long as I can open ports.

On that note, does the $10 per month static IP charge apply if you want V6 static only & are happy with CGNAT for V4?

Hi.

The images in your answer have disappeared, and I'm trying to figure out how set up my Draytek Vigor 130 for my 2degrees VDSL2+ connection.

I've had it running happily for some months but somehow vapourised the settings. I have these back (below); but is this right?

Where does 2Degrees publish this info?

(can't get the darn image to post here, either, damnit.)

Cheers.

P.

@unspecified the images have not disappeared. Also they're 2degrees, not Snap. I have amended your post here.

There is no real reason to be using the DV130 over the Fritz!box. What features are you hoping to gain from doing so? The DV130 is only really good when it is in bridge mode and once in bridge mode it doesn't require any further configuration as configuration (including IPv6) are done on the router it is bridged with.

Oh dear. I log in with a Snap username, and, at least when 2D took over, the settings were different.

The images I refer to are from https://www.geekzone.co.nz/user_public.asp?user_id=22558's head post in this thread; they are still missing.

I don't want a Futzbox, though if you'd like to help me 'correctly' set up the router that I've used happily had for some years now, you'd be welcome.

Does Snap/2D publish the settings anywhere?

Cheers,
P.

@unspecified Everyone I know who has used the DV130 has used them in bridge mode with another router. Not as a router itself. There is really no point.

Even if your router has worked for years you're seriously better off grabbing a Fritz!Box from them. They come preconfigured and even work with IPv6 out of the box and are supported by 2degrees. Also, they're very good routers (much better than just using a DV130 as a router). Seriously, the DV130 just isn't great as a router but is great as a bridge to a better one.

The images are there on the OP... I am seriously not sure what you're on about. They're however based on the Fritz!Box. Unless if you have a static IPv6 allocation you should not be manually configuring this on your router to begin with.

I've had fun with both static and dynamic DHCP allocation and port forwarding being randomly stalled or forgotten on the fritz boxes and have seriously considered switching. They're not perfect by any means.

No router is really perfect by any means.

On the latest firmware however I've found the Fritz to be rock solid.

Hi - Images are missing from what specific thread/Post - can you be more specific please. If you are using Internet Explorer on GZ, I'd use Chrome and you may find images render correctly.

What 'settings' are you looking for ?

Nick.

Are mobile phones subscribed to 2degrees meant to be getting IPv6 addresses?

Searching for ipv6 on the 2degrees website, I can only find info about IPv6 over broadband.

Interesting question. I assumed mobile networks only used IPV4 & CGNAT, but eventually they will have to move to IPV6.

Do you think we will start to see a lot of remote exploits for Android & IOS crop up once every phone has a public IPV6 address?

Mobile networks in the USA by and large support IPv6, so it is absolutely possible to offer, but it is a question of when they would like to offer it. We're not seeing remote exploits at the moment there so I wouldn't expect to see it here either.

Yeah now that my home fibre connection is stuck behind CGNAT, IPv6 is the best way to access my home remotely... but my 2° mobile is stuck in the v4-only dark ages. (I was under the impression that VFNZ mobile supports IPv6, but might be wrong).

FWIW, NAT != firewall. E.g., From both my mobile (and my home router), I can ping other peoples devices on their Ipv4 100.64.0.0/10 addresses.
