Recently I received a new modem from my ISP. The good news is that IP6 is now full dual stack. The not so good news is that I can’t get IP6 to work between the modem and the omnia.
Symptoms:
WiFi using the omnia; only ipv4 addresses
WiFi using the modem; ipv4 and ipv6 addresses
I searched a bit on the net, but I can’t get it to work. Is there someone here who can point me in the right direction? Here is some basic info. Please ask if you want more.
ISP; Ziggo
Modem mode; router (I can’t put the modem in bridge mode myself)
Turris product; omnia
Can you please explain how to setup prefix delegation on br-lan and setting allow downstream delegation of ipv6 prefixes on wan in luci?
I am quite new to ip6 so I lack the knowledge. Strange thing is, ds lite worked like a charm. The omnia (and machines after it) got an ip6 address. That all went automatically.
Did you check with your ISP about using your own device?
Maybe IPv6 delegation is tied to the modems DUID?
Also your screenshot of the modems IPv6 addresses, does not show any delegation. It just shows a single global IPv6 address (.../128) probably the modems external address, and a link-local address (fe80:...).
A delegation should ideally be a /48, some ISP might only handout /56 or /64.
I have contacted my ISP. They said that this particular modem does not send delegated prefixes. The solution was simple; Putting the modem in bridge mode resolved the problem.
Hello there… here the UB modem in bridge, and i do not have full dual stack? IPV6 works here, but after a reboot/update i need to check DNS, and manually select IP4 ‘default gateway’ to get the DNS on ip4 working…
There are a few things that need to be taken into account here.
I got the new SmartWifi modem (Sagemcom F3896LG)
There is a difference in ISP hardware in the old UPC and Old Ziggo areas
Old Ziggo areas tend to have Full Dual Stack
Old UPC areas tend to have Dual Stack Lite
Ziggo is switching to Full Dual Stack in all areas
it may be wise to contact customer support and ask if Full Dual Stack is available for you
It turned out it was not as simple as putting the modem in bridge mode

I hope this brings you a step further. My internet (and omnia) is way more stable, less bufferbloat, faster. And as a bonus I do not have a modem anymore with an intel puma chip. yay.
I will answer this in Dutch, since this is a Dutch provider only issue, me think…( & my technical IT english is crap )
Ik had hetzelfde gezeik met een witte connectbox met puma 6. Torrents en vooral VPN was volkomen kut. Disconnects en heel veel uitval. Na zeuren kreeg ik een UB1318, meteen in bridgemodes, en de boel was stabiel
Toen kwam Ipv6. Ik had en heb precies tzelfde probleem, en dat heeft te maken met je ip4. Op t moment dat je reboot, kom je automatisch met je ip4 op dat 213 ip adres, en niet je eigen 8x adres.
Mijn oplossing is naar luci>network>interfaces en dan naar je WAN > edit . Dat het default gateway uitzetten, saven, en weer aanzetten, saven.
Nou, ik heb nog een ipv6 ergens draaien, en het was ( ook daar ) vooral de stateless setting die t m deed. Heel apart.
Ook daar nu geen enkele 6 naar 4 meer
