@jo20201, hello and sorry for a late response. Could you please answer a couple of questions:

• What machine is a receiver of the lease? If it configured to use DHCPv6 instead of stateless autoconfiguration?
• Are there any other devices in the network that receive the lease properly?
• Which command/software gives you the output you've attached?

Also, could you please collect some verbose log and send it to [email protected] with the "Issue 4667" in the subject? The AdGuardHome.yaml would also be very helpful.

@jeromelarras, hello. Please consider keeping the questions like this in the Discussions section. Such discussion threads are more likely to become a bug report and to be fixed sooner.

@jo20201, hello again. Since I don't know how have you got the attached output, I can only share some ideas of what is going wrong:

• There are dhcp.dhcpv6.ra_slaac_only and dhcp.dhcpv6.ra_allow_slaac fields in the configuration. The "Managed address configuration" and "Other configuration" flags in the Router Advertisement (RA) are both just the negation of dhcp.dhcpv6.ra_slaac_only field of configuration. So could you please try to set both dhcp.dhcpv6.ra_* settings to false to disable the embedded Router Advertisement and leave this part of autoconfiguration to the router.
• Perhaps the RA haven't been sent at the moment of checking the configuration or the host (machine receiving the lease) didn't performed the Router Solicitation (RS) itself at the moment. Does the issue reproduces?

@jo20201, I suppose you might want to enable a router advertisement to make your router advertise itself to the devices in the network as a gateway.

This should work with the ra_allow_slaac set to true, but if it won't, could you please try to set it to false?

[EugeneOne1]

@jo20201, any updates since? If my suggestion was helpful?

the same issue

@jo20201, to ensure, have you enabled the advertising on the router with the ra_allow_slaac both set to true and set to false? If so, could you please collect the logs for us? I've gave the link in the comment on how to do it.
