Can't access OMV Gui with AdGuard Home DHCP Server

Hi everyone,

Hope that somebody will be able to help me with my new problem.

I installed AdGuard Home in docker on my Rpi4 OMV.

As I can't change the DNS in my ISP router (it's forbidden by ISP in France), and as I don't want to configure DNS on each home's devices, I have to use DHCP server of AdGuard Home.

All seem to work perfectly except one thing : i can't access to OMV GUI anymore (and others Web Containers GUI like Heimdall...)

To install I created a macvlan :

sudo docker network create --driver macvlan --attachable --subnet=192.168.1.0/24 --gateway=192.168.1.254 -o parent=eth0 --ip-range=192.168.1.45/32 adguard_network

Then I created a docker-compose file:

version: "3.6"
services:
  adguardhome:
    container_name: adguardhome
    image: adguard/adguardhome:latest
    ports:
      - 53:53/tcp
      - 53:53/udp
      - 67:67/udp
      - 68:68/tcp
      - 80:80/tcp
      - 443:443/tcp
      - 853:853/tcp
      - 3000:3000/tcp
    volumes:
      - /srv/dev-disk-by-uuid-**********************/appdata/adguard/work:/opt/adguardhome/work
      - /srv/dev-disk-by-uuid-**********************/appdata/adguard/conf:/opt/adguardhome/conf #pour persister la configuration
    restart: unless-stopped
    networks:
      adguard_network:
        ipv4_address: 192.168.1.45 #IP fixe assignée au peripherique reseau virtuel Adguardhome

networks:
  adguard_network:
    external: true

Is somebody have a clue of what is wrong? Why can't I reach OMV GUI anymore when I use DHCP server of AdGuard Home?

Thanx guys...

Best guess as with most docker ad blockers you have a port setting of 80:80 in your compose file, if you have not changed OMV's default port which is 80 to say something like 81 then you can't reach OMV's GUI

Hi !

I created a macvlan so normally it is supposed to avoid ports conflicts, doesn't it?

Quote from geaves

AFAIK the port options are not necessary, my bad, but there is a guide here the second post references a stack/yaml file

Ok I installed with the stack in portainer. Easiest way for me, thanx. But the point is I've got the same problem. Can't access OMV GUI when DCHP server from Adguard is activated.

When I look into my ISP router configuration, my Rpi is marked as not connected... I don't know why, because Adguard is marked as connected...

Quote from geaves

one reason why my ad blocker is now on a Rpi

OK, so if I want to make it works correctly, I have to do like you.

What kind of Rpi do I need for that?

Quote from raulfg3

use fixed IP for OMV and use 8.8.8.8 or other like this as DNS sever for OMV ( Do not Use IP of the adguard docker)

Hi! It works perfectly now when I use a static IP in OMV with other DNS server!

Thanx Mr. raulfg3 !!
