I can't use AdGuardHome for ipv6 plz help

[facklemackle]

I've tried to use ip6tables to forward my router's port to Adguard Home's, but nothing works, when I check netstat, it turns out to be inverse in the result,and I've tried to use Adguard Home as my DHCP server, nothing works either, I'm profoundly confused, so if there's anyone who can help me, plz

@facklemackle
Do you mean it doesn’t bind to IPV6?
For me it binds to IPV6 with below settings.

By the way, are you using Gnuton’s firmware?
I think there’s an AdGuardHome Installer which configures AGH as default DNS (port 53) which forwards to dnsmasq (port 853, reconfigured).

Note: 192.168.50.1 is my router’s IP.

dns:
  bind_hosts:
    - 0.0.0.0
    - 127.0.0.1
    - 192.168.50.1
    - '::'

Please show/share full bind_hosts setting.
Also, what’s the error when starting up?

[facklemackle]

I fixed it, this may due to some errors of the firmware for binding issues.... The installer wasn't suitable for me, so I tried to install again with pre-installed entware, and then everything was fine, as you said, I added up :: in bind_hosts,it goes like,
dns: bind_hosts: - 0.0.0.0 - '::'
Sorry for the format, but I don't know how to use "code" to lay out the code.
I didn't see any errors,and I checked the wiki,it said it can be only one global address for both ipv4 and ipv6, 0.0.0.0 or '::',so maybe this is the problem for starting up?

Yes, per doc it’s enough to use 0.0.0.0 for binding to IPV4 and IPV6, but in my experience I needed to add '::' to make it work.

The issue could be in any of the following:
a. AGH network code/implementation
b. library used for networking
c. golang itself
d. networking of the firmware
