Firewall issue

Audio Gear Talk RoPieee

I recently noteiced that when rebooting the Ropieeedisplay, I need to have my firewall off in order to it working. The web interface is fine, but the display itself has the “something not right is roon working” display. When I turn the firewall on my roon linux server off, reboot the ropieeedisplay all is fine.

I imagine there’s a port I need to open, any ideas?

thank you

What device is Roon server running on, and is this machine also running firewall?

Ubuntu 24.04LTS with UFW. All other ports are working correctly.

Okay, you’re in luck … this what I currently use on Ubuntu 24.04.3.

Create application profile for Roon

sudo nano /etc/ufw/applications.d/roon

[Roon]
title=Roon Server
description=Roon Labs Core Music Server
ports=9003/udp|9100:9200/tcp|1900/udp|9330:9339/tcp|30000:30010/tcp

Activate UFW application profile for Roon

sudo ufw allow from 192.168.51.0/24 to any app roon

Add IGMP rules for Roon endpoint discovery

sudo nano /etc/ufw/before.rules

### IGMP (Roon) ###"
-A ufw-before-input -s 224.0.0.0/4 -j ACCEPT
-A ufw-before-input -d 224.0.0.0/4 -j ACCEPT
-A ufw-before-input -s 240.0.0.0/5 -j ACCEPT
-A ufw-before-input -m pkttype --pkt-type multicast -j ACCEPT
-A ufw-before-input -m pkttype --pkt-type broadcast -j ACCEPT

Note : Paste above these lines.

# don't delete the 'COMMIT' line or these rules won't be processed
COMMIT

This was recently posted by @Alex_Reusch and is an elegant solution that I’ll likely adopt when I find time or upgrade to 26.04.1.
