I run a linux home server under Rocky Linux 8, latest update. The ISPs router is set in bridge mode and the server is the modem/router of the network.
Otherwise, I have no problems with the server
Problem statement: I cannot stream radio stations (tunein) on my LAN.
I can connect to the wifi speakers with the app and stream music e.g. from my iphone
This is the configuration:
• I have a HD Mesh Router connected to my server and additionally two mesh points. All internet is wifi
• Multi-zone firewalld configuration:
o <LAN NIC> was assigned to zone = internal
o <WAN NIC> and ppp0 connection was assigned to zone = external
<WAN NIC> is pppoe.parent of ppp0
nmcli con add type pppoe ifname ppp0 con-name ppp0 pppoe.parent <WAN NIC> pppoe.user <username> pppoe.password <password>
o Masquerade is enabled for zones internal and external
o Configuration that outgoing packets pass through the Server from Internal network and get forwarded to the External side.
firewall-cmd --direct --add-rule ipv4 nat POSTROUTING 0 -o ppp0 -j MASQUERADE
o firewall-cmd --direct --add-rule ipv4 filter FORWARD 0 -i <LAN NIC> -o ppp0 -j ACCEPT
o firewall-cmd --direct --add-rule ipv4 filter FORWARD 0 -i ppp0 -o <LAN NIC> -m state --state RELATED,ESTABLISHED -j ACCEPT
From the provider of the wifi speakers I found this about ports:
Speakers and controllers (apps, professional controllers) require communication with each other. Therefore, specific ports must be opened to allow this communication:
• 80 : HTTP
• 554: RTSP
• 49152: MediaRenderer UPnP "listening"
• 49153: Configuration UPnP "listening"
• 49154: MediaServer UPnP "listening"
Open range between 50000 to 64999 for MediaRenderer and 60006 for Media Server.
Furthermore, all UPnP requires multicast access to the 239.255.255.250:1900 along with the appropriate IGMP messages and control for multicast.
I also found this:
The following router ports should be open on your router to allow a seamless network communication with a network-enabled device Router ports: 3813, 443, 80, 8080, 3689 TCP, 554, 5297, 5298, 5353 UDP multicast
I opened all ports on internal and external zone and checked for rejected UDP packages (dmesg ,journalctl -x -e) and opened these protest too, but no luck.
I would really appreciate if here is somebody who could throw me a lifeline with the firewall configuration.
Thanks for your insights.
