How to enable DHCPv6 in AGH?

[Waldorf3]

I have a perfectly fine working setup with AGH serving both DHCP and DNS for IPv4, but after enabling IPv6 on my router, my devices are now getting ISP provided DHCPv6 and DNSv6. I need IPv6 in order to be able to connect to IPv6-only servers.

AGH > settings > DNS settings > DHCP IPv4 Settings show a normal configuration, but no range can be added under DHCP IPv6 Settings - the fields are grayed out. I have a feeling this could be the problem?

Essentially I just need to know how to enable IPv6 from AGH to see if that will solve the problem.

EDIT

A little more info. My router is a tp-link Archer C7 v5.0 with DHCPv4 disabled. There are apparently no way to explicitly disable DHCPv6 though. Once IPv6 is enabled there are 3 choices available: DHCPv6, SLAAC+Stateless DHCP and SLAAC+RDNNS. I just realized that when using the first two options, clients are assigned the ISP DNS servers, but with the SLAAC+RDNNS option they are assigned the AGH DNS server. I can't say I understand anything about this, other than this part works.

I still don't see any way to set up DHCPv6 STATIC LEASES in AGH.

Remember that IPv6 must be enabled in Home Assistant, try in automatic mode to start and restart the AdGuard Home plugin.

DHCP IPv6 6to4: 2002:3dde:4b11:1::2

DHCP IPV6 private range:

Test on windows with command:

• ipconfig /release6
• ipconfig /renew6

fd61/64 private range DHCPv6:

• IPv6 on HA: fd61:5447:6b5e:e343::1
• IPV6 start range on AdGuard: fd61:5447:6b5e:e343:0:0:0:2

NOTE: restart system after network change (problems with multicast)
