My ipv6 connection has disappeared but interfacet is up and running.
Have tested many thgings but have no succes.
It was working until I installed Policy Base Routing program.
Have someone any suggestion to get connection to ipv6 to working?
I using Native from isp.

Thank you !
Hi @octopus, please post the network and firewall configs:

Try deleting this from the network config then try to restart wan6 (ifup wan6).

No, it won’t re-create one. But it should have allowed the dhcpv6 to happen like before. What’s in the system log after running ifup wan6?
Okey, I removed the duid but i didn't save that string........
How can I get a new one generated if needed?
this is after ifup wan6

You should be able to run:

Thanks that give a new duid. 
But can't still get any ipv6 address.
and I have changed in, /lib/netifd/proto/dhcp.sh
from
[ -z "$clientid" ] && clientid="$(proto_dhcp_get_default_clientid "$iface")"
[ -n "$clientid" ] && clientid="-x 0x3d:${clientid//:/}"
to
`[ -n "$clientid" ] && clientid="-x 0x3d:${clientid//:/}" || clientid="-C"``
[11 mars 2026 20:42:33 CET] daemon.warn: odhcpd[2391]: No default route present, setting ra_lifetime to 0!
Can someone have a look at my config for any problem(s)
