Original GitHub issue: https://github.com/netbirdio/netbird/issues/5352

I have NetBird set up in a container:

services:
  netbird:
    image: netbirdio/netbird:rootless-latest
    container_name: netbird
    mem_limit: '512m'
    cpus: 1
    restart: unless-stopped
    user: 1000:1000
    network_mode: host
    volumes:
      - ./config-netbird:/var/lib/netbird
      - /etc/localtime:/etc/localtime:ro

And AdGuard Home set up in another container:

services:
  adguard:
    image: adguard/adguardhome
    container_name: adguard
    mem_limit: '512m'
    cpus: 1
    restart: unless-stopped
    user: 1000:1000
    ports:
      - 53:53/tcp
      - 53:53/udp
      - 3000:3000/tcp
    volumes:
      - ./data-adguard:/opt/adguardhome/work
      - ./config-adguard:/opt/adguardhome/conf
      - /etc/localtime:/etc/localtime:ro

My NetBird is set up, so that other devices use this device as a DNS server.
My AdGuard has the following trusted proxies set up:

  trusted_proxies:
    - 172.16.0.0/12
    - 127.0.0.0/8
    - ::1/128

But requests coming through NetBird show up with the client IP 172.18.0.1. Or if I use AdGuard Home with network_mode: host then localhost (127.0.0.1). Shouldn't I see 100.x.y.z in AdGuard for these requests?
