Odhcp6c problem with ipv6

Hello in logs i have multiple
Server returned message status 0
And my dual stack connection doesn't work...

To make it work i need to use 2 pppoe one for ipv4 and one for ipv6...

If i try to use 1 pppoe that supports both ipv4 and ipv6 my devices receive only a ipv6 address...

I think this is a openwrt problem as my legacy modem (openwrt based) that supports ipv6 handle it properly.

Try to extract its network config with Telnet/SSH/HTTP and compare with the current one.

I think my config is good. My ISP have some strange configuration with ipv6 so I think we should trace it down and adds some fix to odhcpd so I'm here to ask how to trace it down


Anyway may network config

Take notice that i don't use dnsmasq.... I use odhcpd for dhcpv4 and dhcpv6

Any help? Pls

I would be happy to help but my IPv6 is not native and the connection is IPoE.
Let's hope there's someone more experienced.

Ah, I see you also have TIM and a Whitebox too, small world this is :slight_smile:

I had manager to get IPV6 "sort of working" but it was terribly unreliable and I just gave up: in the end, I used the he.net tunnel for both the lan and the guest networks.

Yep... Ipv6 from Tim is sh*t but problem here is not performance but connectivity with mobile device..
Did you have the same problem?

Nope, packet loss was through the roof and it was unusable.
In the linked post you can find sections of my config, you're welcome to try with those.
