Hi, ich komme gerade nicht weiter.
also es geht um `business.myhermes.de` (`www.myhermes.de` funktioniert)
sobald unbound aktiviert ist, kann ich die domain nicht erreichen.
ich habe sicherheitshalber alle DNSBL entfernt und deaktiviert (protokol zeigt kein laden von sperrlisten).
einstellungen sind wie folgt aktiv geblieben
unter allgemein:
- Flush DNS Cache during reload
- Register DHCP Static Mappings
unter überschreibungen:
- eine lokale domain und ein host, beide keinerlei ähnlichkeit mit myhermes.de oder hc.de hat
unter erweitert:
- Aggressive NSEC (testweise deaktivieren hat nicht geholfen)
query forwarding und dns over tls
- eingeschaltet (aufgelistetet dns server sind: 1.1.1.3, 1.0.0.3)
unter schnittstelle-diagnose-dns abfrage bekomme ich oft unterschiedliche antworten:
A business.myhermes.de. 85432 IN CNAME gkp.prd.a0562.prd.hc.de.
gkp.prd.a0562.prd.hc.de. 60 IN A 34.149.95.23 1.1.1.3 53 msec

unter berichterstattung-unbound DNS scheint es normal zu laufen..
2025-03-04 16:42:10 PC-**.**.**.com A business.myhermes.de. Pass Cache NOERROR 4
2025-03-04 16:42:09 PC-**.**.**.com A business.myhermes.de. Pass Recursion NOERROR 5
nur wenn ich bei opnsense die dns diagnose (wie oben) mehrmals durchlaufe, kommt das
2025-03-04 16:44:49 localhost A business.myhermes.de. Pass Recursion NOERROR 5
2025-03-04 16:44:49 localhost AAAA business.myhermes.de. Pass Recursion NOERROR 60

2025-03-04 16:43:24 localhost TXT business.myhermes.de. Drop Local SERVFAIL 0
weiss jemand rat? ich dachte ich frag mal hier, nicht dass das ein unbound problem ist.
danke.
bin etwas weiter
hab je ein ping an `business.myhermes.de` geschickt, während ich den externe dns server jedesmal gewechselt hab.
unbound protokol hat dann aufschluss gegeben:
1.1.1.3 und 1.0.0.3 filtern raus, während 1.1.1.1 und 8.8.8.8 antworten.
übergehe ich lokal den opnsense als dns server und setzte direkt auf einen der vier, funktionieren alle.
wieso antworten 1.1.1.3 und 1.0.0.3 mit 0.0.0.0 wenn unbound fragt, aber beim client antworten sie mit der richtige ip (34.149.95.23)?
weiss dazu jemand was, oder kann es verifizieren?
danke
hier noch die logs:

Laut dem Log
Quote2025-03-05T13:14:42 Debug unbound [23866:0] debug: sanitize: removing public name with private address <gkp.prd.a0562.prd.hc.de.> 0.0.0.0#53
bekommt Unbound eine private IP zurück, und diese gibt er nicht freiwillig weiter.
Wenn ich 1.1.1.3 direkt abfrage (nicht über Unbound), bekomme ich auch 0.0.0.0 zurück. Von 1.0.0.3 bekomme ich aber 34.149.95.23.
Woher die Antwort tatsächlich kommt, lässt sich schwer feststellen, wenn du unverschlüsselte DNS Uplooks nutzt. Die Anfragen könnte bspw. der ISP einfach auf einen anderen Server umleiten.
Ich bekomme von diesen Cloudflare-Servern auch nur komplett blödsinnige Ergebnisse:
# nslookup business.myhermes.de 1.1.1.3
Server: 1.1.1.3
Address: 1.1.1.3#53
Non-authoritative answer:
business.myhermes.de canonical name = gkp.prd.a0562.prd.hc.de.
Name: gkp.prd.a0562.prd.hc.de
Address: 34.149.95.23
Name: gkp.prd.a0562.prd.hc.de
Address: ::
Diese Server sind offenbar funktional kaputt, denn die Antwort "::" würde zu einer Blockade führen, wenn man (per Default) zuerst IPv6 verwendet.
Bezeichnenderweise liefert die "nicht-filternde" Version 1.1.1.1 nur eine IPv4, was korrekt ist, denn für den Alias existiert kein IPv6-Eintrag.
danke viragomann und meyergru.
war doch keine gute idee vorgefilterte dns server zu nutzen, bin wieder auf 1.1.1.1 und DNSBLs aktiviert.
obwohl es in der konsole keine probleme gibt und ich immer die gleichen antworten bekomme, egal welchen dns server ich wähle.
hier ein finaller lookup vergleich zwischen client pc und opnsense (vorsicht lang.. leider gibts kein [spoiler][/spoiler] tag)
- 5 gesetzte server: ohne, 8.8.8.8, 1.1.1.1, 1.1.1.3, 1.0.0.3
da bei allen immer die gleiche antworten kamen, nur mit 1.1.1.3
- 3 gesetzte query types: ohne, A und AAAA
= keine Fehler und keine ipv6 ip
