I’m working to transition an ubuntu server running LXD containers from an ethernet connection to a wireless connection.
I can’t get my Gerbera container (DLNA media server) to DLNA broadcast over a wifi connection. The DLNA broadcast works with a bridged ethernet network profile, but not a wifi routed network profile.
I setup a routed network profile using the following guide. A container using the routed network profile gets an IP on the host network and can access the outside internet interface with wifi only. DNS resolution works too.
However, when I installed Gerbera in a ubuntu 20:04 container it doesn’t seem to broadcast its existance to the home network using the routed wifi network profile. When I ping multicast 184.108.40.206 from within the container I can’t see the packets on the host using tcpdump to monitor the wifi interface.
I’ve tried flushing the nftables ruleset, multicast routing solutions (pimd & mrouted using info at link below), but all without success.
Can anyone help?
