Hallo, bin jetzt auch Besitzer eines BambuLab A1 Drucker und hab folgendes Setup am Laufen mit dem es funktioniert.

@viragomann
Kann sein das es ein Update gegeben hat im Bambu Studio und es funktioniert jetzt.

Mein Setup:
Zwei Netze: IoT (Bambu), Kids (dort ist der PC mit der Bambu Software), beider per WLAN Verbunden (TP-Link Omada)

Schritt 1: UDP Broadcast konfigurieren
  • Interfaces: IoT, Kids
  • Mulitcast Addresses: 239.255.255.250
  • Source Address: 1.1.1.1
  • Listen Port: 1990

Schritt 2: Firewall Regel IoT (nachdem der Broadcast zwischen den Netzen konfiguriert ist benötigt es eine Regel die den Traffic aus dem IoT Netz gestattet.
  • Interfaces: IoT
  • TCP/IP Version: IpV4
  • Protocol: UDP
  • Source: #Printer IP#
  • Destination: 239.255.255.250
  • Destination port range: 1990 - 1990

Schritt 3: Jetzt funktioniert der Broadcast und die Software kann den Drucker "discovern". Damit die Verbindung funktioniert benötigt es noch eine Regel welche den Verkehr zwischen Software (PC) und dem Drucker gestattet.

  • Interfaces: Kids
  • TCP/IP Version: IpV4
  • Protocol: Any
  • Source: Kids Net / oder PC IP
  • Destination: #Printer IP#
  • Destination port range: Any

Die Software läuft auf einer Windows 11 Kiste, es benötigt auch dort eine Firwall Regel welche Broadcasts auf Port 1990 entgegen nimmt.

Vielleicht hilt das dem einen oder anderen beim Setup des Weihnachtsgeschenks

Freundliche Grüße

Me neither. Also those "50 attacks per hour via browser" is probably just the browser downloading a truckload of assets and ads rendering a perfectly normal 2025 web page.

Da hatte ich schon viele, die das tun, z.B. von HP. Wenn man die lässt, melden sie den Verbrauch nach Hause, checken, ob Firmware-Updates vorliegen und bestellen Verbrauchsmaterial nach.

Die Firmware-Updates machen ggf. Third-Party-Cartridges unbrauchbar - habe deswegen gerade einen HP zurückgeschickt.

Am Rande nutzen sie Cloud-NTP-Server.

Der Nachfolger - ein Lexmark - ist nicht viel anders.

Cool, you have a trusted network of some kind.  You use segmentation.

I presume most are and I think that it is much more effective than apparmor on the client.

I challenge the idea that the backend is "open and everything is allowed," because there shouldn't be access to the backend.  Only if there is an exploitable vulnerability in one of the services, which is in the realm of possibility (however unlikely).  I want to give OP some credit, despite the other wild and alarmist claims.  I don't buy that their OPNsense is getting hacked like this without receipts.

I don't know about the VLANs, but I access all my OPNsense UIs from LAN, because that is the most trusted network. And we use individual admin accounts and strong passwords.

Good catch :) and yes I meant without a password because clients on the same LAN can't be blocked by rules.

So you don't think that most are using VLANs then?  I don't have any metrics but it seemed like that was the main reason to use OPNsense vs. the ISP-provided or retail router.

Quote from: OPNenthu on December 26, 2025, 06:47:27 AMHow many OPNsense users are on a flat LAN with open access to their management interfaces?

> 90% I guess? If by "open" you mean only the firewall rules, not the absence of a strong password, of course.

Quote from: someone on December 23, 2025, 05:46:33 AMI have connections through the browser attacking my system trying to break through apparmor. It shows up in auditd log file. Its a mile long. Using this as your endpoint protection or a similar app protects your operating system and  the LAN side backend of opnsense which is open and everything is allowed, thats how they were breaking my separate opnsense router.

How many OPNsense users are on a flat LAN with open access to their management interfaces?

You can always check the roadmap whats next to me migrated under MVC/API.
The area that is currently being worked on is usually part of the Major release roadmap.

Genau das ist der Punkt, den ich am wenigsten verstehe ... Drucker, Scanner, Lautsprecher ... kommt bei mir alles ins vertrauenswürdige Familiennetz. Ich kauf da halt keinen China-Kram, sondern Geräte mit Doku, was sie tun. Lautsprecher z.B. ist eine Airport Express an der Stereoanlage. Drucker Brother mit Ethernet und SNMP ... was tun denn moderne Drucker so? Ich hatte noch nie einen, der nachhause telefoniert hätte. Meiner braucht sogar fürs Firmware-Update ein externes Tool.

Isolieren tue ich ganz anderen Kram 🙂
