What firewall rules do I need to add to use QOBUZ-connect?
The program is QBZ for Linux.
Thank you for your help.

Hi and welcome.

Because the app is for LAN use, firewall rules should not be needed.

However, as Zorin 18 is a fork of Ubuntu 24.04 I used the latter in search criteria in Brave A.I. search engine:

" Based on the provided search context, there is no specific information detailing the exact firewall rules required for QOBUZ-connect.

However, general guidance for Ubuntu 24.04 and QOBUZ-connect suggests the following:

  • QOBUZ-connect Behavior: The QOBUZ desktop application may request firewall pass-through to function correctly. Users have reported the app asking for these permissions, implying it needs network access for streaming or discovery services.
  • Default Ubuntu Policy: Ubuntu 24.04 uses UFW (Uncomplicated Firewall) with a default policy of deny incoming and allow outgoing . For most desktop applications like QOBUZ, allowing outgoing traffic is sufficient.
  • Recommended Action: If QOBUZ-connect fails to work, ensure that outgoing traffic is allowed (which is the default) and check if the application prompts for permission. If you are using a strict firewall, you may need to allow traffic for the specific QOBUZ application profile or port, but specific port numbers for QOBUZ-connect are not provided in the context.
  • Troubleshooting: If you have manually configured UFW rules that block outgoing traffic, revert to allowing outgoing by default with sudo ufw default allow outgoing . For detailed UFW management, you can use the GUFW graphical interface or check the application's documentation for specific port requirements.

AI-generated answer. Please verify critical facts."

Zorin comes with Gufw (Gnome uncomplicated firewall) but is not active by default. Open Gufw and turn it on. Doing so allows all traffic out but no traffic in.
