Firewall settings on an Ubuntu desktop with Roon Core

Right ports for firewall

Hi, Not official support but, the Roon core must be reachable not just via UDP 9003 and TCP 9100 - 9200 ports, but multicast and broadcast communication must also be allowed in the firewall. See: https://help.roonlabs.com/portal/en/kb/articles/linux-install and Android Roon Remote looses connection to Core (daily) - #46 by CRo and/or Can't find Roon "Core" from Remote - #8 by brian
