Does IPv6 require something different configured to block ads effectively?

logi · 2024-08-20T19:37:34.208Z

With IPv6 OFF I get 97% of the ads blocked, tested with Test Ad Block - Toolz

If I turn ON IPv6 I will get 30% of the ads blocked.

I am using:

Blocklist: HaGeZi Pro++

Upstream DNS Servers (those are for IPv4 and IPv6):

https://dns.cloudflare.com/dns-query

https://dns.quad9.net/dns-query

Also, in the dashboard I can see as Average Upstream Response time servers: [::1]:53 , that's for IPv6

Am I doing something wrong? Thanks

Checking, please await.

@Bruce I checked /etc/AdGuardHome/config.yaml file

dns:
   bind_hosts:
      - 0.0.0.0

You only have 0.0.0.0, that's for IPv4, should you have to add ::1 for IPv6?

I have seen the standard OpenWrt standalone (not the GL integrated) AdGuard Home setup and configuration using:

dns:
  bind_hosts:
  - 127.0.0.1
  - ::1
  - 192.168.8.1 (router IPv4)
  - fdd7:b412:b6c1::1 (router IPv6)

I know that 0.0.0.0 is any host, but I don't know if that includes IPv6 hosts?

Hi,

I have tried this by my side, the IPv6 enable, and the ADG works ok, which can support block IPv6 traffic.

For some reasons it doesn't work with the default configuration, I have not done any customization, after checking the logs I found a lot of AdGuardHome errors, actually hundreds, they are all the same errors, do you know what they mean and how can I stop and fix them, these sequence will repeat every minute:

Also, those timeouts in the logs sync with the AdGuard Home dashboard, with response times over 1 sec

I have seen the standard OpenWrt standalone (not the GL integrated) AdGuard Home setup and configuration using:
dns:
  bind_hosts:
  - 127.0.0.1
  - ::1
  - 192.168.8.1 (router IPv4)
  - fdd7:b412:b6c1::1 (router IPv6)

Did you configure these?

logi · 2024-08-26T11:18:06.199Z

bruce:

Did you configure these?

@bruce the Router is configured in IPv6 Passthrough mode, therefore It doesn't have an IPv6 address, I only configured the following, is that OK? Thank you:

dns:
  bind_hosts:
    - 127.0.0.1
    - ::1
    - 192.168.1.1
  port: 53

bruce · 2024-08-26T11:39:13.262Z

My router did not configure these, the ADG also works ok which filter the IPv6 traffic.
I assume it did not require to add the ::1 and 192.168.1.1, etc..

logi · 2024-08-26T11:51:30.476Z

Thank you, that means with 127.0.0.1 is enough for IPv4 and IPv6?

bruce · 2024-08-27T09:37:53.331Z

At lease the ADG works (filter the IPv6 traffic) with the default yaml, verified in 2 pcs MT6000.

logi · 2024-08-27T19:14:29.587Z

Thank you for the confirmation, I appreciate the help
