EdgeRouter Lite 3 IPv6 configuration
Hi;
I am trying to configure the EdgeRouter Lite 3 with two subnets on eth1 and eth2.
The router is behind a Cable Fritzbox. So I get IPv4 and IPv6 addresses. All my devices get both IPv4 and IPv6 addresses, when connected to Fritzbox directly, however, when I connect Edgerouter Lite to Fritzbox, it gets both IPv4 and IPv6 from Fritzbox on eth0, while, it does not relay/advertise the IPv6 prefix to any of eth1 and eth2.
The configuration of IPv6 in Fritzbox is as follows:
In the EdgeRouter Lite firewall, I have rules for the firewall ipv6_name icmpv6 and ports 546-547/udp.
For the interfaces in ethernet I have:
I still cannot get ipv6 on eth1 and eth2, but I get ipv6 on eth0.
What am I missing here for eth1 and eth2?
Thank you in advance

The configuration of IPv6 in Fritzbox is as follows:
Router advertisement in LAn active
ULA: Assign ULA as long as there is no IPv6 connection(recommended)
Additional IPv6 routers in the home network:
Also allow IPv6 prefixes that other IPv6 routers announce in the home network
This FRITZ!Box provides standard Internet access
Set router advertisement preference (higher preferences are preferred by clients): middle
DNS server in the home network:
Also announce DNSv6 servers via router advertisement (RFC 5006)
DHCP server in the home network:
DHCPv6-Server in der FRITZ!Box für das Heimnetz aktivieren:
Select which information the DHCPv6 server should provide in the home network.
Assign DNS servers only: FRITZ!Box is announced as a DNS server via DHCPv6.
For the interfaces in ethernet I have:
eth0:
dhcpdv6-pd:
pd: 0
prefix length: /60
interface:
eth0:
host-address: ::1
prefix-id: :0
service: slaac
eth0:
host-address: ::1
prefix-id: :1
service: slaac
eth0:
host-address: ::1
prefix-id: :2
service: slaac
firewall:
in:
ipv6-name: wan_in (Configured in the firewall ipv6-name)
local:
ipv6-name: wan_local (Configured in the firewall ipv6-name)
ipv6: address autoconf
router-advert:
prefix: ::/64
I still cannot get ipv6 on eth1 and eth2, but I get ipv6 on eth0.
What am I missing here for eth1 and eth2?
Thank you in advance

Hallo,

Firmware?
Config is actually what exeactly?
And DHCP on in the FritzBox dows what, especiaaly since the ERL3 handels all the clients?
Clients hinter EdgeRouter-X bekommen keine IPv6-Global-Unicast-Adresse
Gruss,

Can also be seen with a Fritzbox serving Dual Stack connections with prefix delegation and firewalls in a cascade setup like above:

etc.
Here is a corresponding Cisco router example.
