Pihole auf Ugreen NAS - Kein Internet wenn Router DNS auf NAS IP-Adresse eingestellt wird

Help Deutschsprachige Hilfe
1

Hallo, ich habe Probleme Pihole auf meinen Ugreen NAS DXP2800 zum Laufen zu bekommen. Ich habe es über einen Docker installiert (das image habe ich in der Docker App heruntergeladen), danach das Passwort gesetzt und das DNS von meinem Router (Fritz Box 6670 Cable) auf die IP Adresse vom Nas eingestellt.

Hier die Einstellungen von Pihole

Expected Behaviour:

Pihole sollte nun die Anfragen beantworten und unerwünschte Queries Blockieren.

Actual Behaviour:

Wenn ich nun den Router auf die Nas ip-Adresse einstelle verlieren alle Geräte die mit dem Wlan verbunden sind den Internetzugang. Ich komme nicht mal per Lan in die fritz.box Seite rein (komischerweise geht es aber wenn ich mich per Wireguard in mein Heimnetz verbinde).

Debug Token:

This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations.  This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected.  Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.

NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.

[✓] ** FINISHED DEBUGGING! **

Ich bitte um Hilfe, ich bin etwas am verzweifeln weil ich schon vieles probiert habe wie Ports umstellen, Einstellungen in Pihole, Pihole als Projekt anlegen. Ich bin aber auch neu in der Welt von Docker, VM, NAS usw, daher kenne ich mich noch nicht wirklich aus.
Vielen Dank schonmal im Vorraus.

LG Julian

Fast alle Geräte machen DNS Anfragen an Server nur über den standard DNS Port 53.
In der Port-Zuordnung muss Container-Port 53 zu NAS-Port zugeordnet sein.

Wenn DNS.LISTENINGMODE(INTERFACE SETTINGS) auf LOCAL(Allow only local requests) gestellt ist werden nur DNS anfragen des lokalen subnetzes beantwortet.
Im falle von docker bridge wäre das 172.17.0.0/16 und nicht dein LAN.

Zur Behebung gibt es zwei Möglichkeiten:

  1. DNS.LISTENINGMODE auf ALL(Permit all origins) zu stellen.
  2. In den UGREEN docker Einstellungen den Netzwerkmodus von bridge auf host

Möglichkeit 2 würde Pi-hole erlauben die echte IP des Clients zu sehen, jedoch ist dann keine Port Zuordnung mehr möglich und Pi-holes Ports müssen in Pi-hole Einstellungen geändert werden um keine Konflikte zu verursachen.

INFO: Mittlerweile ist docker version 2025.10.3 verfügbar, die Fehlerbehebungen betreffen dein Problem jedoch nicht direkt

Das kam nachdem ich auf host geändert habe:

Außerdem weiß ich jetzt nicht mit welchem Port ich die Weboberfläche aufmachen kann.

Obwohl der container CAP_NET_BIND_SERVICE hat, wird das Nutzen der Ports 53 und 123 dennoch verwehrt.

[...]
dnsmasq: failed to create listening socket for port 53: Permission denied
[...]

Hast du noch andere Prozesse die Ports 53 und 123 nutzen?

Alternativ besteht immer noch die Möglichkeit Netzwerkmodus bridge zu verwenden und passend DNS.LISTENINGMODE auf ALL(Permit all origins) zu stellen und Container-Port 53 zu NAS-Port 53 zuzuordnen.

Wie finde ich das denn heraus? Außer Pihole habe ich noch Home Assistant auf einer VM laufen
