Proxmox + Docker + AdGuard - Network problem

Hi all,

I’m working to migrate all my add-ons from my Home Assistant to my new VM with HAOS + another VM with AdGuard (and after Nginx, MQTT, Wireguard) with docker container.
I found a lot of tutorial but…still problem with my network configuration.

My Proxmox server has an address like 192.168.3.30.
My VM (host of my docker containers) has also the same network (192.168.3.31).

  1. My first question is: regarding all my future containers, could I have another network format like 192.168.30.01 ? If yes, How can I organize it ?

  2. Currently, I can have Adguard Home working by setting my docker compose with :

network_mode = host

→ I tried to make another configuration with “macvlan” solution, but I didn’t find the right way to make it working (because I still don’t have all knowledge of docker).
(For example:

Without the “host method”, I can manage Adguard (on port 3000), I have an access to the monitoring (on port 80), but if I configure the DNS on another device, nothing happen.
I think I have a problem with the network configuration.
Any idea how can I reach to realize my VM docker configuration ?

Many thanks for your help.
